How to optimize the particle size distribution of positive electrode materials for lithium batteries?
1. Optimizing material morphology: Preparing the morphology of ternary materials into large single crystals similar to lithium cobalt oxide can improve their compaction density.
2. Adjust particle size distribution: Ensure that the particle size distribution is reasonable and avoid a particle size distribution that is too narrow or too wide, which can lead to a decrease in compaction density. The purpose of improving compaction density can be achieved by mixing products with different particle size distributions.
3. Using materials with similar D50 particle size, if there are differences in D10, D90, Dmin, and Dmax, it will also result in different compaction densities. Appropriate particle size distribution can improve the compaction density of materials.
4. Control the electrode plate process: Use conductive agents with good conductivity during electrode plate production to reduce the amount of conductive agent used. During the slurry adjustment process, disperse the conductive agent and binder evenly, which can improve the compaction density.
5. Avoid overvoltage: Overvoltage can cause a decrease in battery capacity, deterioration of cycling, and an increase in internal resistance. Therefore, it is necessary to control the compaction density of the polarizer to avoid excessive increase.
6. Considering porosity: The porosity of the electrode is an important indicator for determining the amount and rate of liquid absorption of the electrode, which directly affects the performance of the battery. Appropriate porosity can ensure the penetration of electrolyte and the performance of the battery.
7. Choose the appropriate particle size distribution width: The larger the particle size distribution width, the larger the overall particle size, and the lower the energy density of lithium-ion batteries. Reducing the overall particle size appropriately can effectively improve the energy density of the electrode.
8. Using a laser particle size analyzer for testing: The particle size of positive electrode materials is usually measured using a laser particle size analyzer, with D50 considered as the average particle size, which helps optimize the energy capacity and power supply of lithium batteries.
9. Considering rate performance and high-voltage solid materials: For materials that require high rate performance, D50 is designed to be smaller to shorten the distance of Li+solid-phase diffusion inside the positive electrode particles.
For high-pressure solid materials, D50 is relatively large, and a bimodal approach is adopted to fully fill the gaps between small particles and large particles, in order to achieve the densest packing effect.
