Solid Power introduces all-solid-state lithium metal batteries

1 min read

Solid Power has announced the production and delivery of the company’s first-generation multi-layer, multi-ampere-hour (Ah) all-solid-state lithium metal batteries.

Solid-state batteries have long been thought of as the “Holy Grail” of EV battery technology, as the lithium metal anode provides more energy and range than today’s Li-ion design, and the solid electrolyte increases safety by eliminating the flammable liquid electrolyte, which also simplifies battery cooling.

Solid Power says the major benefit of a sulfide-based solid electrolyte is its compatibility with Li-ion production and equipment, meaning the cells can be built in Gigafactories operating today. Sulfide-based solid electrolytes also eliminate expensive cell formation steps in manufacturing.

Solid Power’s first-generation 10-layer, 2 Ah pouch cells were manufactured using the company’s MWh-scale, roll-to-roll pilot line, which mirrors Li-ion production lines. More than 250 prototype all-solid-state cells have been shipped, and Solid Power plans to produce and deliver several hundred additional cells to key strategic partners by the end of the year.
