The anode material is an important part of the battery, responsible for storing and releasing charge. Commonly used negative electrode materials include graphite, tin, silicon, and the like.

Graphite is the most common anode material with good conductivity and stability. It can absorb and store lithium ions and release charge during charging and discharging. Graphite anode materials have high cycle stability and energy density, and are widely used in lithium-ion batteries.

Tin is another commonly used negative electrode material, which has high lithium storage capacity and discharge capacity. However, tin is prone to volume changes during charging and discharging, resulting in a short cycle life of the battery. To overcome this problem, researchers are exploring alloying tin anode materials to improve their cycling stability and capacity.

Silicon is a kind of negative electrode material with high capacity, and its lithium storage capacity is more than 10 times that of graphite. However, silicon undergoes large volume expansion and contraction during charging and discharging, which easily leads to material rupture and deactivation. Therefore, researchers are working hard to develop nanostructured or alloy materials to enhance the cycling stability and electrochemical performance of silicon anode materials.

The choice of anode material has an important influence on the performance of the battery, and researchers are constantly trying to find better anode materials to improve the energy density, cycle life and safety performance of the battery.
