Two different hydrogen evolution inhibitor Bi2O3 and In2O3/sisal fiber-based carbon composites were prepared by in-situ synthesis of carbon. The carbon composites were characterized by XRD, SEM, EDS and N2 adsorption-desorption curves. The results of SEM and XRD indicate that the composites have a good degree of crystallization. A large amount of hydrogen evolution inhibitor particles embedded in the fiber surface can be observed on the surface of the sisal fiber-based carbon material, and the distribution is uniform. The prepared carbon composite material was mixed with a battery auxiliary agent to prepare a lead carbon battery anode material. The electrochemical test results show that the anode material of the In2O3/sisal fiber-based carbon composite material has a longer cycle life and better electrochemistry. Performance, the final capacity can reach 102.25 mAh / g, after 150 cycles, the specific capacity accounts for 79.8% of the initial specific capacity.
