Over 7500 Cycles Achieved in Platinum‐Group‐Metal‐Free Ni–H 2 Battery Through Reversible Hydrogen Spillover

ABSTRACT Traditional Ni–H 2 batteries employing platinum‐group metal (PGM) catalysts exhibit ultralong lifetimes (> 10 000 cycles), yet comparable durability has not been achieved in recently developed PGM‐free systems, mainly due to sluggish hydrogen evolution and oxidation reac...
