A long-lasting, stable solid-state lithium battery
I like it, but I'm also afraid of it.<p>Lithium metal reacts explosively to water, and it's impossible to avoid a vehicle battery cracking open in a bad enough accident. Physics is a stern task master.<p>Existing lithium ion batteries are pretty dangerous, as we've seen from accidents involving Teslas and the like: but so are gasoline autos.<p>It would be hard to persuade me that these batteries aren't substantially more dangerous still.<p>That all said, rapid recharging could be a useful feature for stationary storage batteries, and the higher energy density is a nice bonus, although space isn't really the limiting factor for storing renewable energy. There's a place for this technology, somewhere.<p>I'm always happy to read about new battery chemistry, but always come back to the slogan: Goodenough's batteries are good enough.
