New technology unlocks longer lifespan for all-solid-state batteries

Researchers at the Paul Scherrer Institute developed a manufacturing technique that combines controlled sintering with precise passivation to densify the sulfide-based solid electrolyte argyrodite (Li6PS5Cl), a high–lithium-ion-conductivity material. This approach addresses key reliability and durability hurdles in all-solid-state batteries, enabling longer lifespan and more robust performance.

What applications do you think will benefit most from longer-lived all-solid-state batteries, and what challenges remain to scale this sintering/passivation process to mass production?
