What are the types of lithium battery cells?

There are currently three types of mobile power batteries on the market: 18650 batteries, polymer batteries, and lithium iron phosphate batteries. 18650 battery 18650 lithium battery refers to a battery with a diameter of 18mm and a length of 65mm, and 0 represents a cylindrical battery. The technology of the 18650 battery cell is relatively mature, the battery structure is stable, the specific capacity is high, the comprehensive performance is outstanding, and because of its small size, it can be used in many areas. The disadvantage is that its safety is worse than that of polymer lithium batteries, and the number of cycles of the batteries is lower, about 300 times. The difference between polymer batteries and traditional lithium batteries lies in the processing technology. Lithium batteries are wound and are relatively soft. The polymer is superimposed and has a harder body shape. With the same volume of polymer and lithium batteries, the capacity of the polymer is larger, about 30% higher. And it's safer, and the risk of explosion is small. long lasting. The charge and discharge reached more than 500 times. The disadvantage is that the cost is high. Polymer batteries with the same capacity are at least 100% more expensive than 18650 lithium ion batteries.
