Advantages of Battery metal antimony

Metal antimony can be used in the preparation of new cathode materials because of its flame retardant effect.

Under normal circumstances, as the anode material of lithium ion battery, it should meet the following requirements: 

1. In the embedding reaction of lithium ion, the change of free energy is small, the change of electrode potential is small, the potential is low, and it is close to lithium metal;

2. Highly reversible embedding and stripping reaction, with high charge-discharge efficiency;

3, lithium ion in the solid structure of the negative electrode has a high diffusibility, has a high specific capacity;

4. Excellent electrical conductivity;

5, thermodynamically stable and does not react with electrolyte;

6, low price, easy to prepare, no pollution to the environment.

Lithium-ion battery has the characteristics of high density, long life, green and environmental protection, and has been widely used in electronic products, digital products, electric vehicles, etc.With the progress of science and technology, the demand for batteries is increasing day by day.

At present, reducing the cost and improving the performance of lithium batteries has become the main direction of development, and the key technology to study high-energy lithium ion batteries is to use the positive and negative materials that can be reversibly embedded in the process of charge and discharge.

Among them, cathode material as an important factor to propose the battery capacity and life, has been widely studied in the world.

Antimony and tungsten based materials have good physical and chemical properties, and become one of the key materials for energy storage experts to study the negative electrode.
