Did Scientists Just Solve The Biggest Mystery Holding Back Solid-State Batteries

Scientists now know why solid-state batteries have repeatedly failed.

Two separate studies have identified the physical processes responsible for the short circuits that have delayed commercialization for years, turning one of the industry’s biggest unknowns into a defined engineering problem.

For years, engineers knew how solid-state batteries were failing, but not why.

The batteries repeatedly developed internal short circuits as microscopic lithium structures formed inside the cell and eventually pierced the barrier separating the battery’s…
