AI Technical Summary
Traditional preparation processes make it difficult to achieve uniform mixing and selective growth of specific crystal planes in perovskite titanate materials, which limits the improvement of the material's electrochemical performance. Furthermore, existing anode materials have shortcomings in terms of safety and energy density.
Perovskite titanate material with (311) crystal plane preferential growth was prepared by using density premixing and homogenizer mixing, through "core-shell" predispersion structure and three-dimensional uniform dispersion, combined with Bravais law of crystal growth and the principle of preferred crystal growth.
It improves the lithium-ion diffusion rate and rate performance of the material, enhances the compaction density and energy density of the electrode, improves the cycle life of the material and the battery, and reduces the complexity and cost of the manufacturing process.
