Lithium-ion power batteries are lithium-ion batteries with a capacity of 3AH or more, but nowadays they refer to lithium-ion batteries that can be discharged to drive equipment, instruments, models, vehicles, etc. Depending on the object of use, the capacity of the battery may not reach the unit AH level.

We often refer to the superiority of lithium-ion batteries in relation to traditional cadmium-nickel (Ni/cd) and nickel-metal hydride (Ni/cd) batteries. So what is so great about lithium ion batteries? Compared to lead-acid, NiMH and NiCd batteries, they can basically be summarised as follows:

(1) High operating voltage (3 times that of a NiCd hydrogen-Ni battery);

(2) High specific energy (up to 165 WH per kg is 3 times that of hydrogen-nickel batteries);

(3) Small size (30% smaller than hydrogen-nickel batteries)

(4) Light weight (50% lighter than conventional batteries)

(5) Long cycle life (around 500-1000 cycles)

(6) Low self-discharge rate (only 8% per month)

(7) No memory effect (depth of electrical charge and discharge, does not affect the capacity and life of the battery)

(8) No pollution (no toxic substances in the battery material).

Power lithium batteries are mainly used in various vehicles, ships, aircraft and other internal combustion engine starting, lighting, energy storage, uninterrupted power supply, mobile communications, portable power tools, electric toys.

In recent decades, due to the rapid development of transportation, communication and computer industries, the product series, product types and product performance of power batteries have changed dramatically, so as to meet the needs of different uses. The cross-use or alternative use of various types of power batteries is becoming more and more frequent, and the power lithium battery and the main power batteries show a common development situation .
