Lithium polymer cylindrical battery is a type of battery with high energy density and high flexibility, which is widely used in mobile devices, power tools, medical equipment and other fields. Its unique design and excellent performance make it one of the key components of modern technology.

Electric cell refers to a single electrochemical cell containing positive and negative electrodes, which is not used directly. It is different from the battery which contains protective circuit and housing, and can be used directly. Generally speaking, it is a battery that removes the shell, and the rest is called the battery cell.

In terms of materials used, the positive electrode materials of polymer lithium ion batteries are divided into lithium cobalt oxide, lithium manganate, ternary materials and lithium iron phosphate materials. The negative electrode is graphite, and the working principle of the battery is basically the same. The important difference between the positive electrode materials of polymer lithium ion batteries lies in the difference of electrolytes. Liquid lithium ion batteries use liquid electrolytes, and polymer lithium ion batteries use solid polymer electrolytes instead. This polymer can be dry or glued. At present, most of the polymer gel electrolytes are used.

In recent years, the market for automotive emergency starting power supplies made of lithium polymer batteries has grown rapidly. This type of battery is light in weight and compact in size. It can be held in one hand for easy carrying.
