Breakthrough lithium-air battery tech promises 10x energy density, longer EV range

Researchers developed a WSe2-based catalyst that activates the full surface by adding platinum and creating selenium vacancies.

The modified catalyst accelerates oxygen reduction and evolution reactions while preserving electrical conductivity.

A lithium-air battery using the catalyst showed over 550 charge-discharge cycles and outperformed Pt/C and RuO2 in stability.
