Polymer lithium-ion batteries are referred to as polymer lithium batteries,

18650 is just a small lithium battery cell. Its nominal voltage is 3.7 volts. If you want to form 60 volts, according to the circuit voltage principle, you need to use series connection to increase the voltage. 60 ÷ 3.7 = 16.21, taking the whole number as 17, so as long as 17 18650 cells are connected in series, a battery pack of about 60 volts can be realized, 17 * 3.7 = 62.9 volts.

Lithium polymer battery

This corresponds to the liquid lithium-ion battery. The fundamental feature of polymer lithium batteries is that at least one of the three elements of the positive electrode, negative electrode, or electrolyte uses a polymer material. Polymer lithium batteries used in practice use a polymer material in the positive electrode or electrolyte.
Adhere to the market-oriented, backed by strong research and development technology,

The positive electrode material is divided into lithium cobaltate, lithium manganate, ternary material and lithium iron phosphate material. The negative electrode is graphite, and the working principle of the battery is basically the same. The main difference between them is the electrolyte. Liquid lithium-ion batteries use liquid electrolytes. Polymer lithium-ion batteries are replaced by solid polymer electrolytes. This polymer can be either "dry" or "colloid". Of these, polymer gel electrolytes are currently mostly used.
