Problems with ternary materials and the technical route of ternary materials for 3.7v battery 18650
Problems with ternary materials and the technical route of ternary materials for 3.7v battery 18650. Ternary materials have the advantages of large capacity, good cycle stability, and moderate cost. It can effectively overcome the high cost of lithium cobalt oxide materials, the low stability of lithium manganate materials, and the low capacity of lithium iron phosphate. It has been successfully used in batteries, and the scale of application has developed rapidly. The following editor will take you to understand the problems of ternary materials and the technical route of ternary materials for 3.7v battery 18650.
Problems with ternary materials
1. Due to the cation mixing effect and the change of the material surface microstructure during the first charging process, the first charge and discharge efficiency of NMC is not high, and the first efficiency is generally less than 90%; the gas production of ternary material cells is more serious and safety comparison It is highlighted that high-temperature storage and cyclicity need to be improved;
2. Ternary materials are secondary spherical particles formed by agglomeration of primary particles. Since the secondary particles will break under high compaction, the compaction of the ternary material electrode is limited, which also limits the energy density of the battery core. further improvement; the lithium ion diffusion coefficient and electronic conductivity are low, making the rate performance of the material not very ideal.
3. The impact of increased Ni content
By increasing the Ni content in the ternary material, the capacity of the battery can be increased. However, the cycleability and thermal stability deteriorate. When the Ni content increases, phase transformation occurs during the redox process, causing capacity attenuation. The increase in Ni content also reduces the thermal decomposition temperature, increases the heat release, and causes the thermal stability of the material to deteriorate.
4. Matching with electrolyte
Reactions and charge transfer at the interface between electrolyte and cathode material will affect the performance of 3.7v battery 18650. Corrosion of active materials and decomposition of electrolyte will seriously affect charge transfer at the electrode/electrolyte interface.
5. Uneven surface reaction
Research from the Korea Institute of Science and Technology found that the structure of NCA will change during the charging process. Li on the particle surface is more likely to escape, causing the crystal and particle structure on the surface to become uneven. This change will cause the material to rapidly increase its capacity. Attenuation and impedance rise.
