Solid-State Batteries with Ceramic Electrolyte Interfaces
Quick fact
The interface between a ceramic electrolyte and the electrode can account for over 90% of the total battery resistance, meaning a tiny area can bottleneck the entire battery's performance.
Why this is interesting
You know that your phone battery is flammable? What if we replaced the liquid inside with a piece of ceramic? That's the promise of solid-state batteries, but making the two materials touch perfectly is surprisingly hard—and that's the secret challenge.
