The main advantages of silicon negative electrode through PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC processing are: 1) low potential, high gram capacity, high energy density; 2) High content in the crust and low theoretical cost; 3) High rate, high safety, the fiber itself is uniform, can alleviate the safety problems caused by surface suction in descaling and adsorption; 4) The operating voltage is suitable, slightly higher than graphite, lower than lithium titanate and transition metal oxide.
The main problems of silicon-based negative electrodes are large expansion, low first sales and low rate. The performance can be improved through improved MATERIAL design, improved battery system and PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC removal. The main application problems of silicon-based anode are alleviated. For example, the volume expansion rate of silicon material during alloying reaction (only 16% for carbon material) and the material is easy to powder;
The negative active material is easy to fall off; SEI film is broken due to expansion and reconstructed during discharge, making it in the dynamic stage of damage and repair. The thickness will continue to increase, the interface impedance will increase, and the active substances will be consumed. The main solution is the PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC removal to reduce the silicon based negative impurity content.
