First EVs with solid state batteries to be demonstrated in China

First EVs with solid state batteries to be demonstrated in China

Excerpt from thedriven.io

In what could be described as something of a ground-breaking moment, Dongfeng Motor has delivered 50 electric cars with solid-state batteries for demonstration in China.

The difference between a traditional battery and a solid-state battery is in its electrolyte: by using a solid material for the electrolyte between the anode and the cathode, battery makers can increase energy density (and therefore driving range), or reduce battery weight.

They are considered something of a holy grail for the EV industry, and solid-state batteries also have fewer production processes, can charge more quickly and have a longer life than batteries with liquid electrolytes.

However, despite years of research, there have been no EVs with solid-state batteries released to the market to date. While Nio announced in early January 2021 it would start making EVs with 150kWh solid-state batteries, it does not plan to bring these to market until the fourth quarter of this year.
