...Toyota’s Solid State EV battery
There is a lot of noise on the jungle drums about Toyota going full commercial in 2021 with a solid State battery in a new EV

Japanese car maker Toyota will introduce a solid state battery that can recharge to full in just 10 minutes 2021, a move that could revolutionise the electric vehicle market.

Focus is on the 10 min recharge time, but few details of capacities , energy density, costs ,..etc etc

Posted in the Battery tech forum also by mistake :warn:

Edit..more info suggests that 2021 will only be a prototype,...production models to follow.
Also..

It's estimated that a solid-state car could have a range of 1000 kilometers (621 miles) and take 10 minutes to charge. Solid-state batteries deteriorate less over time, and Toyota aims to retain 90% of the battery's performance over a 30-year lifespan. Toyota leads the solid-state battery patent count, owning over 1,000 related to the technology.
...... To help accelerate development of the technology, the Nikkei reports that the Japanese government is considering spending part of a new ¥2 trillion ($19.2 billion) decarbonization fund in building a solid-state battery production infrastructure in the country. Industrial firms such as Mitsui Kinzoku, petrol company Idemitsu Kosan, and Sumitomo Chemical are all gearing up to make the solid electrolytes.
......Toyota is jointly developing the battery with Panasonic, a leader in battery technology, and had planned to reveal something during the Tokyo Olympics this summer. Though the games were canceled due to the COVID-19 pandemic, Toyota was slow to say when the battery prototypes would make their first public showing. Now, it appears that it'll be sometime in 2021.

Even if the energy density was only 60 Wh/kg*, it would be a game changer simply because of the expected longevity. Imagine what it would be like to have a vehicle that could last a lifetime and be passed down multiple generations without requiring major repairs!

*(I personally think it will be much higher than that, as 60 Wh/kg is on par with Ovonics NiMH batteries from the 1990s, and in reality we may get something closer to 600 Wh/kg)

If they ended up at say, 600 Wh/kg, this would mean I could shove an 8 kg pack into my electric velomobile and have nearly 5 kWh on tap, which would theoretically give a 200 mile range at 60 mph, and it would be light enough to be pedaled significantly faster than a normal bicycle with the EV drive system disabled. It would open the door to some very interesting vehicle design possibilities.

That kind of talk will give me wet dreams about the bikes I can build.
