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.

Hyundai Motor heir Euisun Chung takes over from father after 20 years in waiting

SEOUL — Hyundai Motor Group appointed Euisun Chung as group chairman on Wednesday, cementing his succession from his octogenarian father in a move likely to give impetus to the world's fifth-largest automaker's push into electric vehicles and flying cars. In the first generational handover at the South Korean automobile giant in 20 years, Chung, 49, said he hoped to lead change at South Korea's second-biggest conglomerate as it battles to stay ahead of the pack in a time of rapid technological innovation in the global auto industry. "Carrying on their bold and innovative legacies, I feel privileged, yet also a sense of great responsibility for opening a new chapter of Hyundai Motor Group," Chung said in his inauguration speech to employees. Chung identified autonomous driving, electrification, hydrogen fuel cell, robotics and Urban Air Mobility (UAM) — industry jargon for flying cars — as his initiatives for the future. Hyundai Motor shares were trading up 0.3% after rising as much as 2.5% after the appointment, while the wider market was down 0.6%. Kia Motors and Hyundai Mobis fell 1.6% and 1.1%, respectively.   Legacies Hyundai Motor Group earlier on Wednesday said Chung had been promoted to chairman from executive vice chairman, replacing his father, Mong-Koo Chung, who was made honorary chairman. Key affiliates of Hyundai Motor Group, including Hyundai Motor, endorsed his inauguration unanimously. The appointment makes Chung the latest third-generation leader to take over one of South Korea's family-led conglomerates, which have been credited with lifting the war-stricken country out of poverty since the 1950s. His father took the wheel of the group in 2000 and transformed the company, once mocked for poor vehicle quality, into the world's No.5 automaker. The 82-year-old has been stepping back from frontline operations in recent years, and gave up his board seat in Hyundai Motor earlier this year. Euisun Chung has played an increasingly visible leadership role since September 2018 when he was promoted to executive vice chairman. Hyundai Motor Group invested $1.6 billion in a self-driving technology joint venture with U.S. Aptiv, forged a partnership with Uber on electric air taxis and invested in ride-hailing firm Grab. In July, Chung set a goal to win more than 10% of the global market for battery EVs by 2025.

US Congress lets $8,000 hydrogen vehicle tax credit expire

When Toyota introduced the 2016 Mirai last month in preparation for a launch late next year, it said that the hydrogen car will have a $57,500 MSRP and that there will be a federal tax credit available worth up to $8,000. The problem, as we noted at the time, is that that federal credit was set to expire at the end of 2014. The technical language of the current rule says that someone who buys a fuel cell vehicle, "may claim a credit for the certified amount for a fuel cell vehicle if it is placed in service by the taxpayer after Dec. 31, 2005, and is purchased on or before Dec. 31, 2014." With the 113th Congress now finished up for the year and legislators headed home for the holidays, we know one thing for certain: the federal tax credit for hydrogen vehicles was not updated and will end as we're all singing Auld Lang Syne next week. All of this isn't to say that Mirai buyers won't be able to take $8,000 off the price of the car 12 months from now. For proof of that, we only need to look at other alternative fuel tax incentives and realize that this Congress simply isn't moving fast enough to deal with things that are expiring right now. One of the last things that the 113th Congress did in December was to take up the tax credits that expired at the end of 2013 and renew some of them. Jay Friedland, Plug In America's senior policy advisor, told AutoblogGreen that PIA and other likeminded organizations worked with Congress to extended the electronic vehicle charging station (technically: EVSE) tax credit that was part of the Alternative Refueling Tax Credit in IRS Section 30(C) through the end of 2014. "Individuals can deduct 30 percent of the cost of purchasing and installing an EVSE up to $1,000; businesses, 30 percent up to $30,000," he said. "This tax credit is applied to any system placed into service by 12/31/14 and is retroactive to the beginning of the year. So go out and buy your favorite EV driver an EVSE for the holidays," he said. An electric motorcycle credit was killed at the last minute as Congress was getting ready to leave, but H.R. 5771 did extend the Alternative Fuels Excise Tax Credits for liquefied hydrogen and other alternative fuels. These sorts of tax credit battles happen all year long. In July, Blumenthal introduced the Fuel Cell and Hydrogen Infrastructure Act of 2014, which never got out of the Finance Committee. Back to the hydrogen vehicle situation.
