SVolt Energy Readies Solid-State Battery With 400 Wh/Kg Energy Density For Production

We're not there yet, but getting there.

Excerpt:

"Svolt Energy says it has cracked the code to making solid-state sulfide batteries that promise long life and long range. 

Svolt Energy, a division of China’s Great Wall Motors, has been hard at work creating true solid-state batteries for several years now. In its rush to get there, it may (or may not) have enticed some employees of CATL to join its research department. In any event, CATL sued Svolt and that suit has now been settled — amicably, we presume.

This week, CnEVPost is reporting that Svolt Energy is the first company to create prototype 20 Ah solid-state sulfide battery cells with an energy density of 350 to 400 Wh/kg. Those prototype cells have successfully passed nail puncture and thermal runaway tests at temperatures of up to 200° C. Once those cells are commercially available, they could make it possible for electric vehicles to drive 1,000 kilometers or more on a single charge, according to the company.

Svolt Energy says its sulfide technology has been difficult to develop, but it now has the ability to produce many kilograms of solid-state electrolyte materials, is able to continuously prepare solid-state electrolyte films, and can assemble solid-state soft pack cells with its newly developed production equipment. It has been awarded 109 sulfide battery technology patents, of which 93 cover the manufacturing process.

The 1000 Kilometer (621.3712 miles)Challenge

The downside could be higher costs for manufacturers and consumers as the price of battery raw materials — especially nickel — goes through the roof. In the final analysis, less expensive LFP batteries may be the choice of many automakers as they struggle to balance affordability and range. For many EV drivers, a range of 1000 kilometers may be desirable but totally unnecessary to meet their driving needs."
