For the phenomenon of poor circulation performance at the high temperature of lithium batteries, it can improve its high temperature cycle performance by modification of the positive pole material. At present, the material modification of the positive pole mainly has body phase doping and surface modification.
Body doping includes cation doping, anion doping, composite doping, etc. The cation is mainly aimed at lithium manganate materials. After incorporating low -cost cations, the MN elements are partially replaced in the crystal, which increases its average price and decreases. In the aspect, the strength of the keys between cations and oxygen is higher than the key strength between the manganese ion and the oxygen, so that the structure is more stable and suppress the occurrence of the Jahn-Teller effect. Commonly used mixed yang ion elements include Al, MG, Fe, Ni, etc. The doping of the ucchic ions mainly includes F, CR, and S2*, etc., using these electrocomputer -negative anion parts to replace oxygen ions, thereby improving the stability of the material. Composite doping is a variety of cations and anion [21-].
The method of body phase doping can improve the cycle performance of the battery to a certain extent, but it will cause the initial capacity of the lithium -ion battery to decrease, and the most ideal doping method has not yet been found. The surface modification method can reduce the direct contact between the material and the electrolyte and reduce the surface area of the material, thereby reducing the dissolution of metal ions. The more commonly used methods are to cover the materials with metal oxides, metal fluoride and more stable positive poles.
In addition to the modification of the positive pole material, it is also covered with the surface of the litter poles, thereby reducing the deposition of metal ions in the negative electrode surface in the electrolyte.
