THE WORLD'S FIRST ANODE-FREE SODIUM SOLID-STATE BATTERY

Summary from the TLDR newsletter

The Laboratory for Energy Storage and Conversion has created the world's first anode-free sodium solid-state battery. The battery brings the reality of inexpensive, fast-charging, high-capacity batteries for electric vehicles and grid storage closer than ever. It has an architecture with stable cycling for several hundred cycles and is more affordable and environmentally friendly to produce than lithium batteries. Sodium, common in ocean water and soda ash mining, is an inherently more environmentally friendly battery material.
