Surface oxidation, not water, drives Prussian blue battery failure

Дата публикации: 01-07-2026 20:40:04

Like a delicate fabric that becomes damaged during drying, a promising next-generation battery material has faced an unexpected challenge: Removing water to improve performance can actually shorten battery life. Now, a Korean research team has identified surface oxidation occurring during the dehydration process as the true cause of performance degradation and developed a new dehydration process to overcome it.
