Batteries Lose Charge When They 'Breathe'

21 Dec 2025 | Abstracted from Futurity

Researchers found that batteries degrade over time due to "chemomechanical breathing" - tiny expansions and contractions during charge cycles that cause strain and damage. Uneven particle movement leads to stress cascades, cracks, and reduced lifespan. Using advanced imaging, scientists observed this in real time and suggest pressure control and better electrode design could improve durability.
