For decades, hybrid vehicles have relied on nickel metal hydride (NiMH) battery technology — reliable, yes, but also aging.

Researchers at POSTECH identified a new battery degradation mechanism triggered by deep discharging. Avoiding full discharge ...

A battery works when the original chemicals inside it are still new and unused ... If you could reverse the reaction or add more of the original chemicals, you may be able to keep the reaction going.

These reactions degrade the cathode’s structure and cause ... Gas analysis confirmed the presence of a chemical storm inside the battery: 29 times more gas was generated in the deeply discharged cells ...
