How do we choose lithium batteries in life? How to identify the quality of lithium batteries? According to different classification standards, there are different types of lithium batteries, and the quality is also different. Here I will talk about the classification and selection skills of lithium batteries. I hope it can help everyone, let's take a look together.

According to the battery material selection

At present, the mainstream chemical systems used in lithium batteries are divided into ternary, lithium iron phosphate, lithium manganate, etc. according to the positive electrode material. But each of the three batteries has its own advantages and disadvantages. For example, the ternary battery is not as safe as lithium iron phosphate because of its high energy density; lithium manganate has a shorter life than the ternary battery, but the cost is low...

How to achieve the best of both worlds? 

Among them, the manganese-based multi-composite lithium battery used in the products of Topband Lithium Battery Company is an excellent solution at present. Different materials are reasonably matched to form a new composite material to form a manganese-based multi-composite lithium route with lithium manganate as the core. It not only effectively improves the performance of lithium batteries, but also successfully solves the short board of poor high temperature performance of lithium manganate. It has good performance at medium and high temperature after multiple actual measurements. It can achieve no leakage, no fire, and no explosion, and truly achieve the effect of 1+1>2 .

Choose according to the shape of the battery.

Lithium batteries are divided into cylindrical, square aluminum shell, and polymer soft packs. When choosing, generally choose according to the size of the voltage capacity: if the voltage capacity is small, it is recommended to choose a cylindrical type; if the voltage capacity is large, it is more appropriate to use a square aluminum shell.

Choose according to the charge and discharge rate

Lithium battery are divided into capacity type, power type, medium rate type, and high rate type. The maximum charge and discharge rate of the capacity type cells is within 1C, the power type cells are within 3C, the medium rate type cells are within 5C, and the high rate type cells are above 10C or even 30C.

Users should pay attention when using lithium battery products: do not use in extreme environments; do not frequently deep charge and discharge; use a suitable charger to avoid high current; do not "full charge" "overcharge", do not need " "Activate" lithium battery, do not need to be fully charged for storage. Follow the correct use method to ensure your own interests and safety.
