Abstract

A carbon- and binder-free Ti@Ru material is synthesized through a facile and controllable strategy. A Ti@Ru based Li–O₂ battery can effectively avoid the subsidiary reactions, and can be reversibly and continuously cycled for more than 500 cycles with an efficiency ca. 100%, exhibiting an ultra-cycling stability.
