Lithium battery customization is mainly to meet some people who have special needs for lithium batteries. For example, lithium batteries need to be used in high temperature environments for a long time, and they can be waterproof and dustproof. Of course, the key to a lithium battery depends on its battery cell. Nowadays, there are mainly three types of power cells for lithium batteries on the market: lithium iron phosphate, lithium manganate, and ternary lithium.
The advantage of lithium iron phosphate lies in its performance, safety and service life. The disadvantages are also obvious. The life of a single battery of lithium iron phosphate battery is long, about 2000 times, but the life of the battery pack is short, generally about 500 times. , And poor low-temperature performance. However, due to its high cost performance, most people who choose lithium battery customization will choose lithium iron phosphate as the battery cell.
Lithium manganate is a battery material with a long history of use. Its safety is relatively high, especially its ability to resist overcharge. In addition, its material price is relatively cheap, and the production process requirements are not high, the disadvantage is that the high temperature performance is poor.
Ternary lithium has the advantage of forming a synergistic effect inside the same cell, and it has the three requirements of stability, activity and low cost of the material structure. Compared with the other two batteries, the safety performance of ternary lithium is much worse, and there is a hidden danger of thermal runaway, and a large amount of toxic gas will be generated after thermal runaway, which is more dangerous.
