“…When the mass of the mediator is involved in gravimetric specific capacity, the specific capacity of such Li-O 2 batteries will be decreased manifold. Most recently, a stable non-carbonaceous electrolyte has been developed for Li-O 2 batteries, but the use of carbon based cathode still causes the formation of Li 2 CO 3 and cell failure after tens of cycles [25]. Therefore, the development of non-carbon based cathode materials is of great importance for pursuing stable operation of Li-O 2 batteries.…”

Lithium-oxygen (Li-O 2) batteries have extremely high theoretical specific capacities and energy densities when compared with Li-ion batteries. However, the instability of both electrolyte and carbon-based oxygen electrode related to the nucleophilic attack of reduced oxygen species during oxygen reduction reaction and the electrochemical oxidation during oxygen evolution reaction are recognized as the major challenges in this field. Here we report the application of boron carbide (B 4 C) as the non-carbon based oxygen electrode material for aprotic Li-O 2 batteries. B 4 C has high resistance to chemical attack, good conductivity, excellent catalytic activity and low density that are suitable for battery applications. The electrochemical activity and chemical stability of B 4 C are systematically investigated in an
