Cylindrical lithium battery is a kind of lithium-ion battery. Its shape is cylindrical, so it is called cylindrical lithium battery. According to the cathode material, cylindrical lithium battery can be divided into lithium cobalate (LiCoO2), lithium manganate (LiMn2O4), lithium nickel cobalt manganate (LiNiMnCoO2 or NMC), lithium nickel cobalt aluminate (LiNiCoAlO2 or NCA), lithium iron phosphate (LiFePO4) and lithium titanate (Li4Ti5O12).
There are many types of cylindrical lithium batteries, including 14500, 14650, 18500, 18650, 21700, 26650, 32650, etc., which are widely used in special equipment, medical equipment, instruments, handheld devices, security communications and other fields.
Cylindrical lithium battery structure
A typical cylindrical battery structure includes: shell, cap, positive pole, negative pole, diaphragm, electrolyte, PTC element, gasket, safety valve, etc. Generally, the battery shell is the negative pole of the battery, the cap is the positive pole of the battery, and the battery shell is made of nickel plated steel plate.
Advantages of cylindrical lithium battery
Compared with soft package lithium battery and square lithium battery, cylindrical lithium battery has the longest development time, higher standardization, more mature process, high yield and low cost.
Mature production process, low PACK cost, high yield of battery products, and good heat dissipation performance.
The cylindrical battery has formed a series of internationally unified standard specifications and models, which are mature in technology and suitable for mass continuous production.
The specific surface area of the cylinder is large, and the heat dissipation effect is good.
Cylindrical batteries are generally sealed batteries, and there is no maintenance problem during use.
The battery shell has high withstand voltage, and no such phenomena as square and soft packed battery expansion will occur during use.
