Product Description:

High purity silica for silicon-based negative electrodes is a silicon-based material specially developed by Haosen Mineral for the current promising development of silicon-based negative electrodes. With high specific capacity and wide resources, silicon-based negative electrodes are one of the most promising negative electrode materials. The current high-end graphite gram capacity has reached 360-365mAh/g, close to the theoretical gram capacity of 372mAh/g, which is difficult to meet the increasing demand for high energy density. The theoretical specific capacity of silicon-based negative electrode is as high as 4200mAh/g, making it an ideal substitute material for graphite negative electrode. The main advantages of silicon-based negative electrodes are: 1) low potential, high gram capacity, and high energy density; 2) High content in the Earth's crust, low theoretical cost; 3) High magnification and high safety, it is a uniform fiber that can alleviate safety issues caused by surface suction during detachment and adhesion; 4) The working voltage is suitable, slightly higher than graphite and lower than lithium titanate and transition metal oxides.

Main application areas:

Lithium battery silicon-based negative electrode, energy storage battery silicon-based negative electrode.
