What kinds of cells do lithium batteries include? solar street light-litelsolar manufacturers

At present, there are three main types of mobile power cells on the market: 18650 cells, polymer cells, and lithium iron phosphate cells. Compared with the former two, the technology of lithium iron phosphate battery is immature, and the fatal shortcomings of large size and high price make it impossible to move power supply at scale. This article introduces the first two types of batteries. 18650 cell 18650 type lithium battery refers to a battery with a diameter of 18mm and a length of 65mm, and 0 means a cylindrical battery. The technology of 18650 cells 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 ranges. The disadvantage is that its safety is worse than that of polymer lithium batteries, and the number of cycles of the cells is low, only about 300 times. The difference between polymer batteries and traditional lithium-ion batteries lies in the production process. Lithium batteries are wound and are soft in volume. The polymer is superimposed and the body is relatively rigid. For the same volume of polymer and lithium batteries, the capacity of polymer is larger, about 30% higher. And safer, with less risk of explosion. long lasting. Charge and discharge reached more than 500 times. The disadvantage is that the cost is high, and the polymer battery of the same capacity is at least 100% more expensive than the 18650 lithium-ion battery.
