- Researchers discovered that electrical imbalances at grain boundaries in solid electrolytes cause lithium dendrites, leading to battery failure.
- Adjusting processing conditions of the LLZO electrolyte reduced negative charges at boundaries, easing ion movement and reducing electron leakage.
- This modification increased critical current density by over 300%, enabling faster charging, longer lifespan, and improved safety for solid-state batteries.
