How to solve the safety of lithium iron phosphate battery? 1. Improve the safety of the electrolyte. There is a high reaction activity between the electrolyte and the positive and negative electrodes, especially at high temperatures. In order to improve the safety of the lithium iron phosphate battery, it is more effective to improve the safety of the electrolyte. One of the methods. The potential safety hazards of electrolyte can be effectively solved by adding functional additives, using new lithium salts and using new solvents. 2. Improve the safety of electrode materials. Lithium iron phosphate batteries and ternary composite materials are considered to be low-cost and high-safety cathode materials, which may be popularized in the electric vehicle industry. Regarding the positive electrode material, a common method to improve its safety is coating modification, such as surface coating the positive electrode material with a metal oxide. 3. Improve battery safety protection design. In addition to improving the safety of battery materials, commercial lithium batteries adopt many safety protection measures, such as setting battery safety valves, thermal fuses, connecting components with positive temperature coefficients in series, using thermally sealed diaphragms, and loading Dedicated protection circuits, dedicated battery management systems, etc. are also means to enhance safety.
