AI Technical Summary
In existing lithium-ion batteries, FeTiO3 anode materials suffer from severe lithium loss, unstable SEI film, low capacity, and poor cycle stability during cycling, which are difficult to effectively solve using traditional coating methods.
The preparation method of FeTiO3 anode material using Li2C2O4 coating involves coating the FeTiO3 surface with Li2C2O4 to form a dense and stable SEI film, thereby constructing a lithium-ion transport channel, compensating for lithium loss, and improving the lithium storage capacity of the material.
It significantly improves the initial capacity and cycle stability of the anode material, reduces the degree of polarization, improves ionic conductivity and energy density, suppresses material deactivation and lattice volume expansion, and simplifies the preparation process.
