Bulk phase doping. Generally, metal cations are used, such as magnesium ion (Mg2+), aluminum ion (Al3+), titanium ion (Ti4+), zirconium ion (Zr4+), yttrium ion (Y3+), barium ion (Ba2+), etc.
Bulk phase doped ions use oxygen in the same lattice to form a stronger chemical bond, which plays a role in stabilizing the structure, and then PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field improves the cycle life and thermal stability of the material.
Surface coating. Generally using metal oxides, commonly used metal oxides include magnesium oxide (MgO), aluminum oxide (Al2O3), zirconia (ZrO2), titanium oxide (TiO2) and so on.
On the one hand, the surface coating reduces the reactive interface between the MATERIAL and the electrolyte, reduces the side reaction, inhibits the dissolution of metal ions, and optimizes the cyclic performance of the material. On the other hand, the coated material can also stabilize the oxygen atoms on the surface of the cathode material and restrain the surface structure change during the charging and discharging process, which is beneficial to the cycle and storage performance of the ternary material.
Process optimization. The optimization process includes optimizing the crystal size and morphology, reducing the amount of residual LITHIUM on the surface, and reducing the content of fine powder in the MATERIAL, etc. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field has a beneficial effect on the electrochemical performance of ternary materials.
