Research progress of metal oxide glass anode materials for lithium-ion batteries: A Review

In recent years, amorphous glass has been widely used as an anode material for lithium-ion batteries due to its amorphous structure which is conducive to the migration of lithium-ions. Among them, metal oxide glass anode materials have high charge/discharge capacity and excellent cyclic stability. It is expected to solve the problems of low graphite anode-specific capacity of lithium batteries, the collapse of the layered structure, and the sharp decay of cyclic capacity of charge/discharge. Therefore, this paper reviews and analyzes the research progress of metal oxide glass anode materials, especially tin-based and vanadium-based glass materials. Then, this paper proposes performance optimization strategies for glass anode materials. Besides, the prospects for the research of anode materials for lithium-ion batteries are also presented, in the hope of inspiring new ideas and further research in practical applications
