What are the requirements of NiMH battery pack processing manufacturers for positive electrode materials?
What are the requirements of NiMH battery pack processing manufacturers for positive electrode materials? Positive electrode active materials are the most critical core materials of lithium-ion batteries, and positive electrode materials are the basic basis for determining the use direction of lithium-ion batteries. The positive electrode is the core component of lithium-ion batteries, and its quality directly affects the performance of the battery. The positive electrode materials in lithium-ion batteries are all lithium-containing oxides. Generally, the higher the lithium content, the higher the capacity.
At present, the performance and price of NiMH battery pack positive electrode materials are bottlenecks that restrict their further development towards high energy, long life and low cost. One of the key technologies for the development of high-energy lithium ions is the development of positive electrode materials. In theory, materials with layered structures and spinel structures can be used as positive electrode materials for lithium-ion batteries. Compared with negative electrode batteries, the development of positive electrode materials is slightly slow.
What are the requirements of NiMH battery pack processing manufacturers for positive electrode materials?
1. NiMH battery pack reaction should have a large Gibbs free energy to ensure that a high battery voltage can be supplied;
2. The change of Gibbs free energy during discharge should be small to ensure that the output voltage is close to a constant;
3. The positive electrode material should have a low oxidation potential, that is, a higher voltage relative to metallic lithium;
4. It should be as light as possible, but can store a large amount of lithium to ensure a large capacity;
5. Lithium-ion batteries have good electronic conductivity;
6. The structure is stable within the entire operating voltage to ensure a long cycle life;
7. NiMH battery pack materials are cheap and low in toxicity.
8. The particle size of the positive electrode material will directly affect the preparation of NiMH battery pack slurry and pole pieces. Generally, large-particle material slurry has low viscosity and good fluidity, can use less solvent, and has a high solid content.
9. The density of the positive electrode material is closely related to the atomic weight of the elements it contains, the crystal arrangement, the degree of crystallization, the sphericity, the particle size and distribution, the density, etc., and is affected by the preparation process. The density of positive electrode materials is divided into loose density, tap density, powder compaction density, pole piece compaction density, theoretical density, etc.
10. Lithium-ion batteries have a large diffusion coefficient in positive electrode materials, and can maintain the proper speed under different current charging and discharging conditions.
Generally speaking, the key performance indicators of positive electrode materials for lithium-ion batteries are: chemical composition, crystal structure, particle size distribution, tap density, specific surface area, pH value, first discharge specific capacity, first charge and discharge efficiency, cycle life, etc. The performance of lithium-ion batteries depends on the structure and performance of the internal materials of the battery used, and the positive electrode material is more directly decisive. Therefore, the positive electrode material of lithium-ion batteries must meet the basic performance requirements of lithium-ion batteries.
