Why do Haibo iron phosphate lithium batteries use soft pack cells?



       Haibo Electric generally uses lithium iron phosphate soft pack cells, and can also use aluminum shell square cells according to customer requirements.

       Why do Haibo iron phosphate lithium batteries use soft pack cells?

The reasons are as follows:1. From the perspective of positive electrode materials, there are mainly ternary, lithium manganese oxide, and lithium iron phosphate.

Compare these three materials:

Cobalt element is relatively active, and the thermal stability of ternary batteries is poor;

Lithium manganese oxide has fewer cycles, which means its service life is shorter;

In terms of comprehensive safety and service life, lithium iron phosphate is the optimal choice for industrial backup power supply scenarios.

       2. There are mainly cylindrical batteries, square batteries, and soft pack batteries in terms of appearance, and the safety of soft packs is also the highest.

There are three packaging modes for lithium iron phosphate battery cells. The first type is the cylindrical cell that we have talked about a lot about, the second type is the square cell (also divided into steel and aluminum shells), and the third type is the soft pack cell.

Due to the small individual capacity of cylindrical cells, a large number of parallel connections are required for high-capacity battery packs, and PACK grouping is not suitable for industrial applications.

       The steel shell form in square battery cells, due to its hard material, can deform and burst in the event of safety hazards. Currently, it is rarely produced and used. The aluminum shell form in square battery cells is commonly used due to its soft material, which can deform but not burst in the event of safety hazards.

       The outer shell of the soft pack battery is a soft polymer, which can only inflate at most and will not explode in the event of safety hazards.

       At the same time, there is a large amount of electrolyte inside cylindrical and square cells, and in the event of safety hazards, a large amount of electrolyte will flow out.

         However, there is only a small amount of electrolyte inside the soft pack battery cell, and in the event of a safety hazard, there is almost no electrolyte overflow.It can be seen that Haibo Electric's lithium iron phosphate battery pack has an absolute advantage in safety performance. Only lithium iron phosphate batteries that have passed various safety tests can eliminate potential safety hazards in use and be responsible to consumers!
