The invention relates to a negative electrode material formulation of a three-layer composite structure for lithium battery. The anode MATERIAL of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC for iron removal is composed of three layers, the inner layer is metal-organic frame material, the middle layer is nano tin dioxide, and the outer layer is zinc fluoride. Among them, the metal center of the metal-organic frame material is a kind of Fe, Co, Ni, Mn, and the organic ligand is a kind of phenylcarboxylic acid and pyridine carboxylic acid.
In this method, the volume expansion ratio of tin dioxide after cyclic charging and discharging can be reduced by confining and buffering the volume change of tin dioxide by the inner metal-organic frame MATERIAL (negative material containing PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC for iron removal) and the outer coating zinc fluoride. The metal organic frame material and zinc fluoride bear the stress caused by the change of the volume of tin dioxide, which can prevent the pulverization of electrodes.
PTMS is the main PTMS magnetic separation equipment professional company, PTMS magnetic separation equipment for kaolin, potassium sodium feldspar, quartz sand removal of iron (Fe2O3). PTMS to provide customers with high quality PTMS magnetic separator, in addition to iron equipment and other products and services, the best choice of PTMS magnetic separator. PTMS develops, designs, and sells mining machinery, iron removal equipment, and dry magnetic separators.
