Comparison of the advantages and disadvantages of lithium ion batteries and polymer batteries

The composition of the lithium secondary battery is such a battery + a maintenance circuit board. The rechargeable battery removes and maintains the circuit board, which is the battery part of the battery. The quality of the battery directly determines the quality of the rechargeable battery. Then remove the maintenance circuit board from the power board to leave the lithium-ion battery cell on the mobile phone. Remove the shell. Digital products such as Bluetooth mostly use soft-pack batteries. The batteries are divided into aluminum-shell batteries and soft-pack batteries (also known as polymer batteries and cylindrical batteries. Generally, mobile phone batteries use aluminum-shell batteries. Notebooks) The computer’s battery uses a series-parallel combination of cylindrical batteries. The advantages of lithium-ion batteries and polymer batteries are compared. Under the same voltage, the advantage of lithium-ion batteries is that the discharge power is large. The limiting current is greater than that of polymer batteries. The core, that is to say, the output performance of the lithium-ion battery is good and the power is large. It can be used in some devices that require instantaneous high current to ensure the stability of the system. Generally it is about 800MAH, and the disadvantage of the lithium-ion battery is Its capacity is small. And the lithium ion battery cell is unstable and easy to blast under short circuit and external harsh environment, and its outer metal shell is extremely lethal when the lithium ion battery cell is short-circuited and blasted. The polymer battery of the same volume is better than Lithium-ion batteries have a 20% larger capacity and strong endurance under stable current output. The advantages of polymer batteries are strong endurance and large capacity. And its appearance is a flexible material as an outer box. If a short circuit causes the battery to swell It will not blast, but will only split, so it is safe.
