Solid-state batteries: Why Toyota's plans could be a game-changer for EVs

Word out of Japan today is that Toyota is working on launching a new solid-state battery for electric vehicles that will put it solidly in the EV game by 2022. Which leads to a simple question: What is a solid-state battery, and why does it matter? Back in February, John Goodenough observed, "Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted." And risking a bad pun on his surname, he seemed to be implying that all of those characteristics weren't currently good enough in autos using lithium-ion batteries. This comment is relevant because Goodenough, professor at the Cockrell School of Engineering at the University of Texas at Austin - it so happens, he turns 95 today - is the co-inventor of the lithium-ion battery, the type of battery that is pretty much the mainstay of current electric vehicles. And he and a research fellow at U of T were announcing they'd developed a solid-state battery, one that has improved energy density (which means a car so equipped can drive further) and can be recharged more quickly and more often (a.k.a., "long cycle life") than a lithium-ion battery. (Did you ever notice that with time your iPhone keeps less of a charge than it did back when it was shiny and new? That's because it has a limited cycle life. Which is one thing when you're talking about a phone. And something else entirely when it involves a whole car.) What's more, there is reduced mass for a solid-state battery. And there isn't the same safety concern that exists with li-ion batteries vis-a- vis conflagration (which is why at airplane boarding gates they say they'll check your carryon as long as you remove all lithium-ion batteries). Lithium-ion batteries may be far more advanced than the lead-acid batteries that are under the hood of essentially every car that wasn't built in Fremont, Calif., but as is the case with those heavy black rectangles, li-ion batteries contain a liquid. In the lithium-ion battery, the liquid, the electrolyte, moves the lithium ions from the negative to the positive side (anode to cathode) of the battery. In a solid-state design, there is no liquid sloshing around, which also means that there's no liquid that would freeze at low operating temperatures. What Toyota is using for its solid-state battery is still unknown, as is the case for the solid-state batteries that Hyundai is reportedly working on for its EVs.

BMW, Toyota outline new tech joint venture, new sports car

Back in June, Toyota and BMW announced a "memorandum of understanding" outlining plans for the two companies to join forces on future products and technology development. On Thursday, they signed a more formal and binding agreement that goes further into detail about the partnership, and it all sounds pretty exciting. The two announced they will work together in four main areas:
Joint development of a fuel cell system
"Set up a feasibility study to define a joint platform concept for a mid-size sports vehicle"

10% of Toyota China dealers may drop due to losses

News about the auto industry in China is usually positive thanks to booming sales and an ever-increasing number of factories across the country. But in some cases, it appears that the dealers with the job of actually selling all of those vehicles are having trouble finding buyers. The result is cars piling up on lots and showrooms resisting against automakers. Japanese automakers already face a tough road to success in China, but the FAW-Toyota joint venture is especially struggling this year. According to Bloomberg, as many as 10 percent of the dealers might have to close or stop selling the brand because they just can't make money selling the vehicles on their lots. Also, 95 percent of the showrooms are reportedly losing money. The issue facing FAW-Toyota sellers is mostly a case of supply and demand. Automakers in China mandate the number and types of vehicles that dealers sell. However, the inventory from all makes is at its highest level since August 2013, according to Bloomberg. The situation leaves dealers with packed lots, and cars often require discounts to move. Making matters harder is that showrooms have annual sales targets, which are linked to bonuses. This money can account for over half of the sellers' annual profits, according to Bloomberg. The FAW-Toyota dealers are pushing back by asking Toyota for 2.2 billion yuan ($355 million) to pay for costs associated with the extra inventory. It also lowered sales targets by six percent earlier this year and has requested no increase in the numbers for 2015.
