What are the main materials for 18650 lithium batteries.

Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the positive/negative electrode material and a non-aqueous electrolyte solution. So, have you learned about the main materials of lithium batteries? Today, BATTSYS editor will briefly answer them, hoping to be helpful to you.

Carbon negative electrode material

The negative electrode materials used in lithium-ion batteries are mostly carbon materials, such as artificial graphite, natural graphite, intermediate phase carbon microspheres, petroleum coke, carbon fiber, pyrolytic resin carbon, etc.

Tin based negative electrode material
Tin based negative electrode materials can be divided into two types: tin oxides and tin based composite oxides. Oxide refers to the oxide of various valence states of tin metal. There are no commercialized products.

Nitrides

There are no commercialized products.

Alloy class

Including tin based alloys, silicon-based alloys, germanium based alloys, aluminum based alloys, antimony based alloys, magnesium based alloys, and other alloys, there are also no commercial products.

Nanoscale

Nanocarbon nanotubes and nanoalloy materials.

nano-oxide

According to the latest market development trends in the lithium battery new energy industry in 2009, many companies have started using nano titanium oxide and nano silicon oxide added to traditional graphite, tin oxide, and nanocarbon tubes to increase the charging and discharging capacity and frequency of lithium batteries.
