The difference between polymer lithium battery and 18650 lithium battery

1. Important application fields are different. The importance of polymer lithium batteries in commercial company products is much larger than that of 18650 lithium batteries in depth and breadth. Most of them can be used with 18650 batteries. The use of polymer lithium batteries is especially in the field of 3C products. Under the requirements of practicality and high endurance of smart products, 18650 lithium batteries cannot do it, but polymer lithium batteries can. 2. There are differences in the electrolyte field. These two batteries are also different in the electrolyte field. Naturally, even the same type of battery, the electrolyte used may be different. What is said here is different. Different, the important thing is that the shape is different. There are three electrolyte shapes used in polymer lithium batteries, namely liquid, colloidal and solid. Different electrolytes have different advantages and disadvantages. The electrolyte of 18650 lithium battery is basically liquid. 3. The processing technology is different. The production and manufacturing process of polymer lithium battery is laminated. This process can change the size and shape of the battery processing and manufacturing at low cost and high efficiency. It can be processed according to the actual application requirements of the company's products. A battery with a suitable shape makes full use of the product space and makes the product more in line with the application requirements of the consumer market. The 18650 lithium battery production process is a winding type, which is a fixed size and shape. 4. The battery shape is not the same. The most intuitive thing in the field of battery cells is that the polymer lithium battery and 18650 lithium battery are not the same in shape. The polymer lithium battery is square, the outer shell is aluminum plastic film, and it is a soft pack. Battery; 18650 lithium battery is cylindrical, the outer shell is steel shell, it is hard packaging; at the same time, the 18650 lithium battery has only one specification size, and its diameter and height are fixed.
