How to improve the characteristics of lithium iron phosphate batteries.32700 battery

release time:2023-08-24 Hits:     Popular:AG11 battery

  

  1、 Factors affecting the characteristics of low-temperature lithium iron phosphate batteries

  1. The positive electrode material selected in lithium iron phosphate batteries has weak electronic device conductivity and is prone to polarization, thereby reducing the volume of the lithium battery.

  2. Negative grade lithium batteries pose a significant threat to low-temperature battery charging, which can compromise the safety factor of rechargeable batteries.

  3. Lithium battery electrolyte: Lithium iron phosphate batteries have an increase in the viscosity of their internal lithium battery electrolyte at low temperature standards, thereby enhancing the characteristic impedance of lithium-ion battery transfer.

  2、 How to improve the low-temperature characteristics of lithium iron phosphate batteries?

  1. From the perspective of the positive grade of lithium iron phosphate rechargeable batteries, both the particle size and resistance of the positive electrode can harm the ultra-low temperature characteristics of rechargeable batteries. The low-temperature charging and discharging characteristics of lithium batteries can be improved based on the positive manufacturing process. Increasing the length of the plan axis can expand the transfer safety channel of lithium-ion batteries, which is beneficial for increasing the volume of rechargeable batteries. According to research findings, the low-temperature charging and discharging characteristics of lithium iron phosphate batteries can release 914 particles with a particle size of 100-200nm at -20 ℃. Nanotechnology of particles can reduce particle transfer pathways and improve their low-temperature charging and discharging characteristics.

  2. For lithium iron phosphate batteries charged with low-temperature batteries, the negative electrode is the most harmful, and the key lies in the transformation of the negative particle size and negative stage spacing. Manpower high-purity graphite is a battery positive electrode material with different layer spacing and particle size. For particles with large layer spacing, the high-purity graphite layer itself has a slightly smaller characteristic impedance and positive ion transfer characteristic impedance from the perspective of antigens. Due to the expansion of the spacing between artificially synthesized high-purity graphite layers and the reduction of particle size, the charging of low-temperature constant current power batteries has made significant improvements to lithium iron phosphate batteries.

  3. When the temperature of the lithium battery electrolyte drops to -20 ℃ or lower, the electrolyte of lithium iron phosphate batteries is prone to problems such as freezing, viscosity increase, and characteristic deterioration. Experiments have shown that the harm of organic solvents to low-temperature charging batteries varies from 70% to 90%, reaching more than ten points. In addition, different lithium salts also pose certain hazards to the charging characteristics of batteries. The experiment found that if only changing the anti-corrosion agent, the low-temperature anti-corrosion agent can increase the charging and discharging capacitance of the rechargeable battery from 8% to 90%.
