Influence of Atomic Deposition Surface Modification Technology on the Cycle Efficiency and Capacity of Lithium Ferrous Silicate Cathodes for Lithium-ion Batteries

This article explored the use of atomic layer deposition to deposit cathode material LF(M)S coated with nano-scale Al2O3(C) film by growth coating, and successfully obtained the composite LF(M)S coated with Al2O3 (C) cathode material. The test results of various electrochemical performance parameters show that the surface modification treatment method can effectively improve the various electrochemical properties of the cathode material. The synthesized LF(M)S was analyzed by a Time of Flight Secondary Ion Mass Spectrometer, and a clear topography and three-dimensional topography of the surface coated with Al2O3 and C were obtained; the surface morphology and uniformity of the deposited layer were studied by Atomic Force Microscope and the crystal structure of the material was analyzed by XRD. The electrochemical performance of the battery assembled with the positive electrode material was characterized by an electrochemical workstation and a charge-discharge tester. The results showed that the surface coating can effectively prevent the side reaction between the material and the electrolyte at high voltage, and reduce the irreversible capacity loss in the first charge and discharge process, because the chemical properties of the coating are not active. At the same time, due to the stable structure and good conductivity of the coating material, the stability of the structure during charging and discharging of the material is maintained, thereby reducing the loss of battery capacity, maintaining good conductivity between the material particles, and improving the cycle performance of the material.
