Cylindrical lithium-ion battery is a lithium ion battery with cylindrical shape, so called cylindrical lithium-ion battery. According to the anode materials, Hub-E cylindrical li-ion battery are divided into lithium cobalt oxides (LiCoO2), lithium manganese (LiMn2O4), lithium nickel manganese cobalt (LiNiMnCoO2 or NMC), lithium aluminum nickel cobalt (LiNiCoAlO2 or NCA), lithium iron phosphate (LiFePO4) and lithium titanate (Li4Ti5O12).
- Mature production process, low pack cost, high battery yield, good heat dissipation performance
- Cylindrical battery has international standard of specifications and models, mature technology, which is suitable for mass continuous production.
- Large specific surface area of the cylindrical lithium ion battery and nice heat dissipation effect
- Cylindrical battery is generally sealed battery. There is no maintenance problem in the use process.
- Cylindrical battery case has high pressure resistance, so the battery will not expand in the use process like prismatic battery and pouch cell.
A typical cylindrical battery structure includes: case, cap, positive electrode, negative electrode, separator, electrolyte, PTC element, gasket, anti explosive valve, etc. Generally, the battery case is the negative electrode of the battery, and the cap is the positive electrode of the battery.
