Scientists have developed a new catalyst technology that could significantly improve the performance and lifespan of lithium-air batteries.
The breakthrough focuses on tungsten diselenide (WSe₂), a two-dimensional material whose surface was previously only partially active in chemical reactions.
The method has led to improved capacity, faster charge-discharge performance, and longer-lasting stability, significantly enhancing overall efficiency and durability of lithium–oxygen batteries.
The team highlights that the findings could advance next-generation energy storage technologies.
In January 2025, DOE-backed researchers unveiled a solid lithium-air battery that delivers four times the energy of lithium-ion batteries, breaking the room-temperature limit.
