502030 lipo battery.Square lithium-ion battery

release time:2023-11-28 Hits: Popular:AG11 battery

　　Square lithium-ion batteries are divided into two types: metal shell packaging (silver white hard shell) and aluminum plastic shell packaging (gray white soft shell, which can be scratched with nails). The metal shell packaging is a lithium-ion battery or liquid lithium battery, while the aluminum plastic shell packaging is a lithium-ion polymer battery. The chemical materials and electrochemical characteristics used in these two types of batteries can be said to be similar, The main difference is that lithium-ion polymer batteries use some colloidal substances to help the battery plate adhere or absorb electrolyte, reducing the amount of liquid electrolyte used. As a result, the packaging of the battery can be changed from a metal shell to an aluminum plastic shell.

　　The shell of a metal shell lithium battery is the negative electrode, and the positive electrode is on a protrusion on one side of the battery; The positive and negative electrodes of aluminum plastic shell lithium batteries are two plates on one side of the battery, and the outer shell is an insulator

　　For square lithium-ion batteries, their model number is generally 6 digits. As shown in the table below. The first two digits represent the thickness of the battery, with one decimal place; The middle two digits represent the width of the battery; The last two digits are the length of the battery. The unit is millimeters. For example, the 606168 lithium battery has a thickness of 6.0 millimeters, a width of 61 millimeters, and a length of 68 millimeters. (Note: Due to the different packaging methods used by different battery manufacturers, the capacity of square lithium-ion batteries of the same model varies within 300mAh.)
