For cylindrical, square, or soft-pack batteries, we ensure insulation and fixation of the tab area. This is achieved by wrapping and bonding the positive and negative tabs to prevent contact with the battery casing or other metal components, thereby avoiding short circuits.

Once the battery cell is wound or stacked, we secure the ends with tape. This ensures the core remains in place and facilitates smooth packaging procedures.with tape to prevent the core from coming loose and to ensure the smooth progress of subsequent packaging processes.

The Cell Edge Bonding is utilized for the edge sealing region of soft-pack battery aluminum-plastic films, enhancing sealing performance and mechanical strength.

The Module (PACK) Stage involves the application of Binding and Protection. This process is utilized during battery pack assembly to provide insulation and isolation between cells, as well as overall binding and fixation, thereby enhancing safety and structural stability.

Some high-temperature resistant tapes, like those made from PI base material, can safeguard your battery cells from damage during processes like welding and baking.

The tape should be compatible with automation production, meeting the high-speed production lines’ requirements for unrolling force, cleanliness, and consistency to ensure efficiency and yield.
