Deconstructing 12V lithium ion battery pack

Composition of lithium battery
Lithium ion battery packs mainly rely on lithium ions to move back and forth between the positive and negative electrodes. During charge and discharge, Li+ is intercalated and deintercalated between the two electrodes. The active material of the positive electrode material is mainly lithium manganate or lithium cobaltate, lithium nickel cobalt manganese oxide material (commonly known as ternary), active lithium complex such as lithium iron phosphate. The negative electrode material is mainly composed of lithium-carbon intercalation compound LiXC6, which is basically a carbon material with good performance and chemical stability, graphite, carbon fiber, glassy carbon, etc. In terms of negative electrode material, graphene has excellent charge and discharge performance. More and more attention has been paid to various lithium battery manufacturers and investment institutions. The electrolytic solution is usually a carbonate-based solvent in which lithium hexafluorophosphate is dissolved, and the polymer uses a gel-like electrolytic solution, and since the electrolytic solution uses an organic solvent, the electrical conductivity is extremely weak. The lithium battery has a small self-discharge property. Allows high current charging while charging. Therefore, the general lithium battery can be charged to 1C;

12v lithium ion battery pack

The 12v lithium ion battery pack is connected in series with 3 or 4 lithium batteries. Synthetic battery packs. The capacity of the battery is determined by the capacity of a single battery cell or the capacity of a battery connected in parallel. It is a new type of battery that is safe and environmentally friendly.
Introduction
12V lithium ion battery pack: According to the material classification, it can be divided into: 12V lithium ion battery pack , 12V lead acid battery pack 12V nickel hydrogen hydride nickel cadmium battery pack, 12V alkaline battery pack. The 12 lithium ion battery pack is composed of three 3.7V lithium batteries connected in series. The voltage of a single lithium battery is 4.2V after being fully charged. In general, it is also called 4V. The voltage of the series battery is added, which is: 4V/cell* 3 electric is also = 12V, which is what we call 12V lithium battery pack.

Battery capacity: Capacity does not have standard capacity. It is determined according to the specific requirements of electrical appliances or equipment. The general capacity is 2200ma/h, 5AH, 10Ah, and some electric vehicles can reach 20AH or 50AH. The more you have, the bigger the capacity. According to the physics formula: in the parallel circuit: I total = I1 + I2 + I3 [1]
Volume: A volume of 12V lithium ion battery pack is determined by the capacity of the battery. There is no uniform specification. The larger the battery capacity, the larger the volume
Weight: Many devices now require large capacity and lighter weight lithium batteries, such as electric vehicles. Previously, lead-acid batteries were used. Nowadays, many electric vehicles have become lithium batteries, because lithium batteries have large capacity, light weight and small size.
Charge and discharge current: The charge and discharge current of  lithium battery is determined according to the power of the device. The electric power formula is: P=UI[1]. On the basis of a constant voltage, the greater the power of the device, the greater the current that needs to be output.
12V lithium ion battery pack use: electric vehicles, power tools, notebooks, yachts, camping spare batteries, RV, home spare batteries, mobile DVD, UPS, GPS, medical equipment, etc.
