As one of the most typical representatives of tin-based oxides, tin dioxide (SnO2) has the relevant characteristics of n-type wide-bandgap semiconductors, and has been used in many fields such as gas sensing and biotechnology. At the same time, SnO2 has the advantages of abundant reserves and green environmental protection, and is considered to be one of the most promising anode materials for lithium-ion batteries.

Nano tin dioxide is also widely used in the field of lithium batteries because of its good permeability to visible light, excellent chemical stability in aqueous solution, and specific conductivity and reflection of infrared radiation.

Nano stannic oxide is a new anode material for lithium-ion batteries. It is different from the previous carbon anode materials, it is an inorganic system with metal elements at the same time, and the microstructure is composed of nano scale stannic anhydride particles. Nano tin oxide has its unique lithium intercalation characteristics, and its lithium intercalation mechanism is very different from that of carbon materials.

The research on the lithium intercalation process of tin dioxide nanoparticle shows that because the particles of SnO2 are nano-scale, and the gaps between the particles are also nano-sized, it provides a good nano-lithium intercalation channel and intercalation for the intercalation of lithium ions. Therefore, tin oxide nano has large lithium intercalation capacity and good lithium intercalation performance, especially in the case of high current charging and discharging, it still has a large reversible capacity. Tin dioxide nano material proposes a brand new system for lithium ion anode material, which gets rid of the previous system of carbon materials, and has attracted more and more attention and research.
