Silicon based anode is one of the most promising anode materials with high specific volume and wide resources. The current high-end graphite gram capacity has reached 360-365mAh/g, close to the theoretical gram capacity of 372mAh/g, it is difficult to meet the increasing requirements of high energy density. The theoretical specific capacity of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic removal of iron is as high as 4200mAh/g, which is an ideal alternative material for graphite anode.
The main advantages of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic are: 1) low potential, high gram capacity and high energy density; 2) High content in the crust, low theoretical cost; 3) High magnification and high safety, which is itself a uniform fiber, which can alleviate the safety problems caused by surface suction in detachment and adsorption; 4) Suitable working voltage, slightly higher than graphite, lower than lithium titanate and transition metal oxides.
PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC The main application challenges of silicon based anode materials for iron removal are as follows: 1) The volume expansion rate of silicon materials during alloying reaction can reach 300% (carbon materials are only 16%), and the material is easy to powder; 2) The negative active substance is easy to fall off; 3) The expansion causes the SEI film to break, and the SEI is reconstructed during discharge, making it in the dynamic stage of destruction-repair, and the thickness will continue to increase, the interface impedance will increase, and the active substance consumption will be increased.
