Glad to see there's a big R&D effort underway around materials to advance the utility of Li-ion batteries in EVs. There's been so much written about the development and use of bigger battery units as a way to up the power and increase the charge, it's refreshing to read about work done in other sectors that can advance the cause. Clearly things have to change/improve on the battery front in order for EVs to really gain traction among consumers.
Unless I'm missing something, the first development in Ann's article (the germanium suboxide anodes) relates to Li-ion batteries, but the second development (the atomic layer deposition process) relates to fuel cells - NOT batteries. Batteries and fuel cells are two different things. What am I missing here? What do fuel cells have to do with making Li-ion batteries which last longer?
I too was confused by this article.The first page was about battery anodes and then jumped to fuel cell materials without an explanation.
As far as this article, the improvements we are and will see in batteries will make EV's a reality, contrary to all the naysayers out there who apparently think the world is a static place.As oil becomes harder to find, EV's will take over more applications. They will initially start with short commutes in the city and I believe in 30-50 years, most of us will be driving EV's wether we want to or not.
I was surprised to see how much work is being done on new/alternative materials for EV batteries, both li-ion and fuel cells. It makes sense, though. If better materials can shrink the size of batteries and/or make them last longer, that will help the whole EV acceptance process.
Ultimately, research such as this will be the way to cut battery costs. Economies of scale will only get us so far, according to a report done by an Indiana University Blue Ribbon panel in 2010. The panel said: "Additional battery R&D may achieve even greater cost reductions, perhaps more significant than the cost reductions expected through economies of scale and 'learning by doing' in the production process."
I agree, Chuck, it's well funded R&D that seems to be behind some pretty amazing breakthroughs, at least in materials, for sustainable and alternative energy sources. I'd like to see more of what that report said. Can you post a link to it?
things change at a tremendously fast paced timing. I read where Tesla began shipping its 4 door sedans from CA, instead of finland where it got the old samples made
the message below it was one of elon iron man musk declaring bankruptcy, in the face of some 1 million in repair costs and mounting to his experiment with the roadster, and li-on batteries expanding when they heat up---It was ironic, but, just today I went to the apple store, with a laptop I bought in 2008 2.4 GB, the li-on battery had expanded beyond its housing, They replaced it without cost. Then we had a discussion about apple making their products statewide, which they replied it may or maynot cost twice as much, depending if the difference in labor cost in china and the usa was ignored. Chinese slaves currently make 3.8 cents when an american worker makees a dollar. Before the last few admins enacted nafta then free trade, we had import taxation to protect us from slavery, while remaining an independent nation, then the lobbies bribed politica to look the other way as slavery became our way of life, or the source of our durable goods, as we so act so we become. If the factor of americas quality of life is a variable of the equasion, as it actually is, then apple could make their goods in america and the costs would remain the same or decrease, if it is ignored them they may or maynot cost more if make in america. One thing is certain as long as slavery and nobility are restored to power in the free world, our quality of life and hope will continue to diminish. Our nations youth and the youth around the world are viewing this from a different perspective, giving consideration to ending nobility and slavery world wide, its called anarchy, historically used to do away with nobility. the world is changing at a fast pace, its interesting ti see how it will all turn out, todays youth self educated in the internet are very aware, capable of great things
jackiecox, you do yourself no favors by using incorrect facts and unsupported opinions to back up your claims. Just one example for your information: You should be aware that Tesla roadsters were not made or assembled in Finland. I think you may be thinking of Fisker, a separate company that also markets an EV, but has no ties to Tesla. Tesla DID use a body constructed by Lotus, a UK company, but they did not assemble the car there.
In terms of the viability of the battery technology in EVs, I would tend to agree that we're not there yet, and I would just note that it has nothing to do with Men in Black, evil corporations or conspiracies (a la "Who killed the electric car?"). Keep in mind that when Orville and Wilber made their first successful flight, there weren't agents out selling tickets to passengers the next day. Free markets work when entrepreneurs take risks and invest their own money in new ideas. If they win, they win. If they lose, they lose and try something different. And it usually takes time.
Regarding your rant about slave labor and such, take a breath. Relax. Maybe you should check the expiration date on your meds.
Oh, and you might want to use a spell checker. No offense , but you need one badly.
In the EV world what promoters and battery manufacturers seem to not pay any attention to is the COST PER MILE!
It does not matter how much you bring down the battery cost, if it does not last.
The Li useful life of between 250 and 400 times, which translates to about 18 to 24 months of EV use in real life driving, before the battery deteriorates to a point that range is seriously reduced becomes a big problem few years from now.
California ZEV mandate requires OEM to Warrant the battery for 80,000 to 150,000 miles depending on the "emissions" certification.
Granted Li battery even after 600 cycles may be still "useful" but not to a person whose 100 miles range is now only 40 miles per charge.
I can see big lawsiuts over when the battery needs to be changed for FREE in the consumers vehicle.
And it is not just the cost of battery replacement, or loss of range per charge but the astronomical depreciation of "used" EV that makes Cost of Driving per mile more than a luxury.
MIROX, those are really good points. And I agree with philipp10, market forces caused by pressure to find more and better alternatives will make improvements in EV batteries, as well as other EV technologies.
You are absolutely right, MIROX. You rarely see the cost per mile estimates given for any EV or hybrid. I always laugh at the ads for hybrids when they say something about great MPG - which relates to absolutely nothing. Your second point is likewise correct. These new cars are given some "range per charge" but that range has such are large deviance over its life, use, ambient temperature, etc. that it too is basically useless. And when somebody's 80 mile/charge car dies at 40 miles at -2 degrees, there will be lawsuits coming.

Where is your data? I have a LEAF and have recharged daily for the past 300 days and there is no sign of battery degradation after 8,000 miles. I don't know how long the battery will last but your data of 250 to 400 times is not supported by the 20,000 LEAFS running today. Some users have logged 20,000 miles and battery reports are reporting no issues.
Your other arguments are all based on this error.
In addition the battery is expected to degrade to 70% as end of life. At this level the battery will have 18 to 20 KWHr capacity which can power a typical house for 1 day or provide peaking power capability to the grid. So while the range will be reduced in an EV, if the range is still adequate then there is no need to replace the lower range battery.
Now for cost per mile - my prior car got 17 mpg and burns preminum gas currentl at $4.07 a gallon for $0.24 per mile fuel cost. The LEAF uses 10KWHr from the grid for 35 miles of range and my average cost for electricity from PG&E is $0.14/KWHr resulting in a $0.04 cost per mile. So the $0.20 per mile savings or $1600 for 8K miles can go toward a replacement battery. By the time I reach 80K miles it will be $16,000 provided gas prices don't rise and if the battery lasts 160K well it paid for the entire vehicle. True we don't know if these are facts yet but I'm liking what I'm seeing and by the way, very little maintanence on a LEAF or EV so far. Brake fluid in 2 years, coolant flush in 3 year, 12 lead acid battery in 5 years and tire replacement.
li-on batteries is wqell said except the e is missing it should be lie-on, the experiment on our unwary public thinking the federal agencies responsibility for credibility im the market place would not allow the EV companies to experiment on the public, trying to decipher the coefficient factor of expansion of lithium as it ages, and becomes dysfunctional. Its not like metal, as it ages it expands, no one knows how much, or what for or what kind of expandable casing it requires to remain fubctional, as most like tsla simply ignore it while the cars heat up and creep a;ong, requiring them to put on their flashers, and hope someone doesn't come up behind a big rig and not see them. Criminality in government takes a broad swath using affirmative action to make scientific evaluations, or in the cse od our once world leading team of scientists at SASA where they more than justified their existence in taxes taken, replaced by an astromaunt, afroamerican, while dismantling shutle2 and constellation. The world is becoming bizarre when we become a slave bnation (free trade) and people like chui, from academia make the calls, a gaggle of idiots destroyinh our youths chances to become involved in our once, independent country, when we made what we consumes
" 0 " must be 6the difference between your eyes, in june, EV sales were less than 3,000. one day soon the real world will see a more viable, end of EV's still remaining because some people can afford tp make the unjustifiable economic decision to buy an EV, if your capable of calculating the variables. Its on a scale with the real value of gold, considering its functional uses, other than the media, and financials media as a source for its economic REAL worth, little btter than lead
The 3D printing revolution seems to have a knack for quickly moving technology ahead by way of collaborative effort and even a little friendly competition -- all of course in the name of scientific advancement.
