Ga 2 O 3 is a promising anode material for lithium ion batteries (LIBs) owing to its high theoretical capacity and low lithiation potential. However, its performance improvement has been seriously hindered by the sluggish reaction kinetics. Herein, Ga 2 O 3 /N doped C nanopapers (Ga 2 O 3 /NC NPs) are firstly designed and synthesized via a scalable biomass‐aided approach. The as‐prepared Ga 2 O 3 /NC NPs deliver high reversible capacity and prominent rate capability as anode for LIBs, owing to its excellent reaction kinetics. It shows high discharge capacity of 477 mAh g −1 after 200 cycles at 0.2 A g −1 , without obvious capacity attenuation upon cycling. After 3 periodic rate performance testing ranging from 0.1 to 1.6 A g −1 , the reversible capacity of the Ga 2 O 3 /NC NPs still retains to 517 mAh g −1 when the current is reverting to 0.1 A g −1 . The low and safe working potential, the prominent electrochemical performance and the scalable synthesis method for the Ga 2 O 3 /NC NPs endow it with great promising toward practical application.
