Lithium-ion current sources in a ball mill and comparing this energy with the binding energies of lithium ions with various metals of a cathode material for mechanochemical destruction. The binding energies of lithium ions in various lithium-containing compounds are shown. The calculation of the technological and design parameters of the ball mill to determine the magnitude of the energy of the collision of the grinding bodies and the grinded material. The graphic dependences are given, allowing to reveal the influence of the ratio of the diameter of the balls and their number on the process of mechanochemical destruction.

Abstract The reasonable design of nanostructure is the key to solving the inherent defects and realizing a high performance of Li2FeSiO4 cathode materials. In this work, a novel heterostructure CNT@Li2FeSiO4@C has been designed and synthesized and used as a cathode material for lithium-ion battery. It is revealed that the product has a uniform core-shell structure, and the thickness of the Li2FeSiO4 layer and the outer carbon layer is about 19 nm and 2 nm, respectively. The rational design effectively accelerates the diffusion of lithium ions, improves the electric conductivity, and relieves the volume change during the charging/discharging process. With the advantages of its specific structure, CNT@Li2FeSiO4@C has successfully overcome the inherent shortcomings of Li2FeSiO4 and shown good reversible capacity and cycle properties.
