Batteries: The Organic iPod/LiO Fire Battery Failures
Monday, October 8th, 2007 running time 18:28
In our biggest failure since the WiFi Episode, Systm trys to power an iPod with Lemons and create a Lithium Ion battery fire. Find out what exactly a battery is... and why we want a battery tech breakthrough in the worst way.
Before we start talking battery, let's get two things clear: First, use rechargeable batteries whenever possible. Second, you should properly recycle batteries whenever possible so they don't end up in a landfill.
Ever wonder what exactly a battery is? We have, and in our search for more something with a higher energy to weight ration than a lead-acid battery we started looking around the web.
Can you power an iPod with a chain of Lemons? Not exactly... you need a lot more current than our lemons could generate, tho we had more than enough Voltage. A lemon battery is a fun project to do with the kids, btw.
How hard is it to turn a Lithium Ion battery into a flaming sparkler, ala those flaming notebook battery problems back in 2006? Harder than we thought. Our LiO cell didn' bcatch, tho the pastic around it did.
Fortunately, we had some pretty good luck gutting a AA battery...

" Hello welcome to very special episode of systm episode twenty where we're actually gonna do nothing unsafe. Okay we're gonna do something -- later on but we've hasn't complains about remembering where safety years so."
" We we have cool guys -- a year now shields and gloves. You know -- chemical gloves on some gloves that's -- that's a big step up for us to. -- are talking about though is batteries battery history technology batteries kind of been on our mind a lot lately extra batteries are. They're really far away from corporate and -- we dream of electric car project electric scooter project looking motorcycle project. For Tekzilla recently did a portable power pack project it pretty much everything you do has batteries and -- somewhere one way or another although I stick to the -- batteries you know the double -- is -- nine holes you know kind of what. You -- it's -- supermarket she's not say well six holes he found some supermarkets yes I'm selling album but they're not very popular we should point out you have your Armani container around a car battery and lead acid battery. Which may mean that -- through the sleeve of your jacket in your your forearm yes but its -- so comfortable. -- talk about what a battery is yes of the battery. He's probably start with the basic what is battery right right it's just. To say it basically accommodations sells the -- seller who chemical cell battery is a device with one or more. Don't manic cells. Which is called block power. I like that combine excel is basically to have cells basically it's too dissimilar metals in an ultralight. Sort. And I like this part made from two different metals committed by assault bridge or -- disk between half selves elect an actually an example of that and what would probably fail meaning biology class in the world is my example of a guided. -- Double a battery again here if you look closely you can actually see. Now there's an anode going to camp neat that's like one half of the cells and and I won't have the cells -- which one is negative."
" The negative would be Indiana OK so you can actually see. The metal that makes -- the anode. Can see that just inside there should be of those things state so in between those is the electoral light which is of black stuff as far as I know supports layer in between Andy and go to. Which basically was the top of the battery was destroyed during these guys section. But basically. That's -- look -- inside of it to. -- double about it. The earliest known battery technology suspected battery technology or -- Baghdad sells them they look like batteries that may have been batteries they may be used for medicinal purposes -- May have been used to galvanize jewelry than they've just been a weird combination. A couple of medals in a pox. It's about gasoline who looked deeply. Yeah exactly and an eclectic eclectic how they can and electric fence you. -- kind of funny -- is basically. 82 dissimilar metals. And massively usually created battery rack case in point we have eleven battery here we have a rather expensive lemon battery here we have a dream with eleven batteries."
" And picnic. You -- you know give or take about no one -- off you know vitamin or potato."
" Well this is our galvanic sound right so we've got -- too dissimilar metals is includes steel though it's dead or nail at most -- This is are exactly or individual batteries so we've got too dissimilar metals like copper and -- covered. This all mean those are two electrodes and we have these in series -- parallel of those are serious. So we're actually hoping to come up with -- enough voltage and current to actually charge. The USB device and we'll understand unconscionable. That we use single cell. That a single cell that's the single so right there -- earlier about who. Six point 65 volts point 63 -- right and her. And what have how many who have been through 2345678. Tell me it's hard when -- 3456789101112. In it doesn't. This doesn't limit."
" Connected in series. Connected in series that's been up the voltage was -- up the voltage but she doesn't that's the limit and had a really good transfer all that has not given the troop point seven volts for its limit -- So we got twelve of them together. They -- the two point one will see about two point one is just because there's a lot lost them to death and you might think like hey that's a good -- let's show the hampers. That's kind of sad didn't think. They with a dozen lemons we still. Not much there really you can't record but when you're getting micro -- out of it. -- So much for or organic iPod charger. But the potential. Not much happening mostly three micro lamps that's really the first things and you know alternate income growth it's actually more from you. That's next the united registered -- but I mean we're talking it was like what 11 -- amp for -- There's about one the lamp for. This thing I generate more electricity than elevenths the problem more aboriginal and -- just tell -- copper top yeah. You can also actually for this experiment using potato potatoes work if you find what really tiny low power. Plants and equivalent of that for you don't break fresh -- tougher pressure potato. Here. Don't go through the hand and I really before. You know we have safety here and and -- normally when doesn't suspect the potato -- so we just got a workman's comp insurance that the office crane and equipment."
" If anyone knows -- OSHA regulations returning potatoes and batteries you know freedom for the information you system at revision3.com. Now Revision 3 revisions. I think. Knowing."
" We didn't."
" I signs teacher a lot of me."
" We do know for a fact that the ones don't generate a lot of average in you mr. Powell hmm. -- example I think. Cole Alley you're junior high school science did that effect that's. In any case those sellers an electrode and and and suspended in something -- As easily solid or liquid electric light so the classic actually battery technology -- want you uncapped that held in the uncapped this. The sort of what we like colleague mature technology which is. Tech industry for something it's been around so long we figured out everything we can't about it and I really think about it much anymore would be able lead acid battery. That would classically -- car battery traditionally which is. Well gee it's a bunch of led good. And we'll -- it in a plastic cases."
" Now you know you're supposed aware protection -- stuff but I'm really when it really just came out of our producers car and he and I don't trust it. Yeah if you really want to have an exciting moment and this."
" We go huge on YouTube. There's not a sealed battery sealed batteries actually something like this where there's some sort of event inside of the we'll let gas out. But the collector like the ass of itself is immersed either like EGM which is Glassman a fiberglass and absorbs you want to light or. An actual gel right so you can you know other basically be a bunch of -- that does not poor out of this you know this there's no sort of user. -- you know use if -- lead our society but traditional let acid battery it was like pretty much the oldest form of common battery. If we pop those two caps off you'd actually be able to add distilled water into that. Two sort of you know bring the battery up to scale. So if I'm battery shopping what are the measurements that I would apply to a battery."
" Well this is how likely go classics they had checked for your goals in and then you're checking for kind of your current or your average month which is off."
" And categorized either and yet militancy and or empowers writes okay. And and half hour is the amount of and -- it can. Throw out of every single hour that's correct okay so what's called empower battery can throw out twelve lamps across the single -- right so is it depleted at that point."
" Well depends on the type of battery because now rechargeable ones are never fully depleted got -- out of Iraq but for the most part instantly --"
" Yeah and we should point out that you've -- to kind of broad categories of batteries rechargeable and not or -- levels are rechargeable are also known as. Primary batteries primary batteries means that whatever electro chemical reaction takes place without the battery is not reversible. Maybe because he and those -- the -- is corroded in the process of generating electricity. Or may mean that it's simply the reaction. Is not reversible in the sense that when you apply current two rechargeable battery usually reverses electro chemical reaction allowing you to use the battery over and over again. That part well. This we're gonna skip over pretty much everything -- let acid batteries in what's kind of the favorite battery technology today not think anything away from nickel metal high drive. Go -- right -- which is just get straight ahead lithium ion batteries. First proposed in 1960s made practical by bell labs when they came over the graphite -- look at my batteries. Use -- as you look for life because this is is that a safe thing to say."
" I think that's as -- as that I meant it. I'm not a battery expert right wow I mean if you hunt down in Seattle or -- chemical variation in the united some combination of chemical stuff that creates a thin line if you want to learn more about that it's a lot of time on the Internet -- about -- But the fundamental thing is that the first commercial devices contain within my batteries can menace our mason commercially available devices it -- batteries came from Sony. In 1991 and we'd like to thank John -- know who's now the University of Texas Austin for making that possible. Because it took us from this in for medical Lenovo high drive I think it wasn't put a hybrid battery around here."
" If you haven't seen these sick of -- these kinds of really cool idea. Of HUSD. We'll plug in. That he displayed in your computer charges it put little cap back on and Brian and yet so double -- battery I like that thoughts. As look at that I -- let's just amazement to just be form factor just so happens to fit right in diameter of the bullet like that."
" Yeah me. Are very particular server thought that idea. That was clever. But -- with -- my batteries obviously almost every I can't imagine notebook being sold today with a lithium ion battery cell phones look at my batteries. IPods will be my batteries can quarters and digital camera -- rechargeable battery -- almost always lithium ion batteries where they have the ability my battery right because everybody's like. -- batteries for quality fired me -- thought discussed the first of all they were making plans for out of the sky and second they weren't exactly lighting themselves on fire. It was a really great interest. There's a really great entry on Wikipedia that talks about with the -- chemistry and I'm gonna read it straight from Wikipedia. Within my chemistry is not safe as such and lithium ion cells require several mandatory safety devices be built in before being considered safer outside the laboratory. These are the shut down separated for over temperature the -- wait -- for internal pressure event for pressure relief informally in Iraq for over current or overcharging. These devices take away useful space inside the cells that an additional layer of on the reliability. Typical their action is to permanently irreversibly disable the cell. Now my wife is watching who's librarians like to point out that yes Wikipedia how to better source of information any fool who has five minutes and web connection to change an entry me completely inaccurate but in this case I believe it's a relatively. Reasonable source quotes. You can listen to kind of cease and action we'll take like a digital camera -- at some point four volts are people lamp battery. And these have the lithium ion cells which look remarkably in shape like double a cells. But if you know be shut down -- fairway tab and events there's all contained in this little bit of circuitry. In between the cells and basically the idea so that if it over heats or strange things start to happen but we like call bad things he's technical term -- That the battery basically the -- you can shut down what happened with all of those batteries were recalled. Is -- either manufacturing defects were flexing within with the mine packets self created small cracks -- in -- material. Nelson you not exactly well that's -- are making out but it actually created the opportunity for overheating and short circuits to be ninety with -- my material. So just for fun a little later in this direction -- on fire and what happens boom because I think it's gonna be a non trivial effort too -- with him fire. Stuff. And it takes more get -- I mean what you punctured the battery on one years."
" The iPod that I wanna. I am personally not just didn't have a right through driver at the time to think and it's an -- I'm breaking in just went to pry it off. And they did have a shield over the battery like I expected. So lose your drivers there his camera right into the battery I hate it when that happened and all I really got with a puff of smoke but I."
" Gotta make when you think about it you batteries are so important anywhere you wanna make electricity portable -- battery or car and you battery. To make advances in electric vehicles when you're talking about scooters and motorcycles or the Tesla roadster you needed to advance in battery technology. You know we talked about one the most expensive components inside the Tesla. Is the fact they had to pull together all of these very small expensive batteries. There's nobody's making a big lithium ion battery -- can drop in their lithium ion battery -- the consulates over thirty years old that this point has been commercially available for close to twenty years. -- it's a small company and -- they're claiming it's in nursing count that three times the power. But about half the capacity so it's a kind of interesting treetops are going to need more cells to get past you want but which really while they're claiming a six minute charge time. And in and seen. Lifetime like twenty. Thousand recharging cycles clockwise -- now that's a lot more than twice that's like twenty years in most cases now relegated to -- your life cycle ten -- and that's a much difference that's a huge difference. They have really scaled up yet but OB nurse and see what other you know a lot of these small companies it's kind of I'm interested to see if any major companies a lot of people are thinking. You know fuel cells hydrogen powered fuel cells are gonna be kind of the next big thing in creating electricity on the fly. --"
" Since the how to -- and this is still relatively large they really haven't convinced them down the practicality and a lot of in normal devices things slow enough."
" Yeah I'm not take care my 42 count high content you'll sign me the other thing is is getting into is you know. Electrical batteries in a rechargeable we have an electrical grid in teetering and tottering occasionally certainly here in northern California in the summer -- especially. But you know -- if you're gonna go to a hydrogen fuel solve your electrical needs then a you have -- you know store and distribute hydrogen and by the way. One of the big things is somebody needs to figure out a way to make hydrogen. Much more cost effective to produce -- right now you make hydrogen by throwing an incredible amount of electricity. Into a couple of electrodes and separating hydrogen oxygen and water. So you end up putting in a lot more power than you get out so all you grad students out there. The cracking you can have the most amazing basic patent the 21 century."
" And you actually have one of those already work cannot give us an email will detect it out and shut off for. -- want to give us the small share of proceeds at that charge is the ability to have an option now I'm Compaq and if you're thinking about your kid going business school they could you map. Don't become an engineer -- physicists to come up with new battery technology you see this hall. I think that the probably trickle down as far as it's going to go with it yeah I think we've kind of done -- to death and -- not -- we just kind of -- battery in and we're good. I'm battered Norton I've -- enough statins if we let ourselves on fire or like Philippine violent fire."
" Using C for technology. So very impressive at the plastic burning off. Printer those plastic. To admit what it says astronaut -- and so it's help. But. Resistance to compete more. -- Science phase. Conspiracy -- something in my helmet and today."
" Love love love. That allows you if you want you to turn around and figure out the average parity need to be pulled embarrassed to basically be hampered measurements and so one thing we did talk rose how can help batteries are -- they have. Voltage. Current measure voltage efforts on what. And and but. Hey out of affairs said that this won't thoughtfully. What's. And and night either exactly or. --"
" You're never Wikipedia moment here they didn't trust myself to it to get this straight but. I like this and you know if my wife is watching -- when you're no guff about within."
" liability to the folder action to permanently in her first -- some. That. It's -- and."
