LFP Module

For improving production efficiency, the positive and negative terminals of lithium-ion batteries have been upgraded from screw hole terminals to flat welding terminals. The new generation lithium batteries require welding equipment for battery connections. Sorting out the demand from the international market, many international customers still prefer to choose cells that can be connected by screws or bolts than flat welding terminals. The following points are pointed out by customers:

Due to the total pack or module needs to be replaced once one cell of the battery pack fails in the operation. As well as, there is a dimension limit on module size for different application cases from the local market, and there is low feasibility to use the same module to meet all pack requirements. Therefore, customers prefer cells with nut/screw terminals for the flexibility of pack installation.

However, Lithium Storage recommends customers select battery modules instead of cells because of the high structural stability and welding reliability of battery modules.
