Atomic-layer-deposited amorphous MoS(2) for durable and flexible Li-O(2) batteries

Li–O₂ batteries (LOB) potentially have the highest specific capacity among all types of metal‐ion batteries but suffer severely from cycle instability and low energy efficiency. In this work, an integrated cathode is fabricated that contains an amorphous MoS₂ thin layer deposited on a 3D conductive carbon scaffold to improve the energy efficiency to ≈83% and cycle life up to 190 cycles. An advanced pressure‐tuned stop‐flow atomic layer deposition (ALD) method is employed to deposit a ≈5 nm thick amorphous MoS2 layer on carbon nanotube forest‐covered graphite foam. It is established that this integrated 3D cathode exhibits high catalytic activity for both oxygen reduction reaction and oxygen evolution reaction. The benefit of the ALD MoS2 in lowering the energy barrier is also supported by first‐principles calculations. Finally, quasi‐solid state flexible LOBs are also assembled that can be stably discharged up to 6 d. This new and rational design of cathode may provide a new direction for achieving high‐performance flexible Li–O₂ batteries.Ming Song, Hua Tan, Xianglin Li, Alfred Iing Yoong Tok, Pei Liang, Dongliang Chao, and Hong Jin Fa
