"The new batteries, which have more than twice the energy density of lithium
ion units, could power electric vehicles more than 300 miles on a single
charge and enter production in the early 2020s, top engineers at the company
said.
Since 2012, Toyota has managed a fivefold increase in the power output of
its experimental solid-state batteries, Senior Managing Officer Soichiro
Okudaira told a conference here.
The current coin-sized cell is still in the laboratory stage. But Toyota
expects the technology to be ready for cars in the early 2020s, Hideki Iba,
general manager for the Japanese carmaker's battery research division, said
separately. "
So this new battery won't be in cars for some five or more years.
"Looking further ahead, Toyota is working on so-called lithium air
batteries, which have energy densities around 1,000 watt-hours per liter.
Their power output is on par with solid-state units.
In lithium air batteries, the lithium cathode used in lithium ion batteries
is replaced with one that interacts with oxygen. This requires less material
and allows for lighter packaging.
Toyota projected those would be ready after 2030."
This is even worse, with such a long lead time it might end up not being
practical for auto use.

Read the book, "The Reckoning" by David Halberstam. If you think GM is bad,
I bet Ford is worse.

Huge, mega-companies like GM don't have to do everything right. Look at all
the many, many screwups by Intel which they just toss on the trash heap.
Heck, at one point they sold their ARM license to one of the companies who
is now eating their lunch!
GM will sell the Bolt and possibly improve it and come out with another
model or two while everyone else (hopefully everyone) learns the nature of
the market and adapts. GM won't go "tits up", they will just loose money on
it for many years ahead before they end up buying cars from someone else and
rebranding them.
