A second major hurdle to the acceptance of lithium-ion batteries is their high cost, much of it due to the catalysts that must be added to speed up fuel cell chemical processes. In the most commonly used fuel cells, the anode is covered with a costly noble metal powder that reacts with the fuel. Researchers at Finland's Aalto University have developed a fuel cell manufacturing method with ALD that allows the cover to be much thinner and more uniform, lowering costs and boosting performance.
The Finnish method depends on the use of alcohol instead of the more common hydrogen as a fuel, along with a catalyst made of palladium. The most common catalyst for hydrogen fuel cells is platinum, which is twice as expensive as palladium. In addition, alcohol is easier to handle and store than the more commonly used hydrogen fuel. The research team says commercial production could start in five to 10 years.
Meanwhile, the plastics processor Rehau, one of 80 partners in the EU's lightweight StreetScooter short distance concept EV, is developing thermoplastic battery housings to save weight and avoid corrosion. Plastic's low thermal conductivity also eliminates the need for the foam sheet thermal insulation used in metal housings. In Rehau's Ultralitec process, up to 27 layers of fiber-reinforced thermoplastic are heated and compression molded. They are then combined with other components added via injection molding to create a battery housing with half the volume and a third less weight than an equivalent housing made of metal.

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
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.
What should be the perception of a product’s real-world performance with regard to the published spec sheet? While it is easy to assume that the product will operate according to spec, what variables should be considered, and is that a designer obligation or a customer responsibility? Or both?
Biomimicry has already found its way into the development of robots and new materials, with researchers studying animals and nature to come up with new innovations. Now thanks to researchers in Boston, biomimicry could even inform the future of electrical networks for next-generation displays.
