Battery Casing Insulation & BMS Protection
External insulation and sealing for battery aluminum casings, retarding heat dissipation. BMS Module Protection.
Termination Fixation & Protection
Insulation and fixation of the cell bottom involves bonding and securing the entire cell inside an aluminum/steel casing. This design cushions impacts, dampens vibrations and provides insulation, while helping control the cell’s dimensions within the casing – preventing short circuits caused by contact between the cell bottom and the casing, resisting contamination, and enhancing mechanical strength. It also prevents the jelly roll from loosening, achieves reliable termination insulation, and resists puncture damage.
Cell Casing & Spacing Fixation
Fills gaps, secures battery cells, provides shock absorption and buffering, and enhances overall safety.
Electrode Weld Insulation & Fixing
Temporarily fix stacked or wound electrode groups to prevent misalignment during transfer to the shell insertion station. Achieve fixation and insulation at tab welding joints to protect tabs and avoid piercing short circuits.
Industry Pain Points
-
-
Poor conformability
The tape cannot fit closely to curved surfaces, resulting in incomplete wrapping.
-
Easy tearing
Low ductility and tensile strength make the tape tear easily during application.
-
Weak adhesion
Insufficient adhesive strength causes lithium battery cells to unwind after winding or lamination processing.
-
Low tape toughness
Poor toughness makes the separator prone to tearing during casing assembly and results in insulation failure.
-
Cell swelling
Volatile gas released under high temperature conditions directly causes battery cell swelling.
-
Cell loosening
Battery cells get loose easily under long-term vibration working conditions.
-
Structural damage
Cell displacement causes irreversible internal structural damage.
-
dhesion failure
Temperature cycling leads to tape aging and loss of adhesive performance.
-
Electrode misalignment
Electrode groups easily shift and misalign during handling and assembly processes.
-
Weld insulation risk
EWelding joints lack effective insulation protection, bringing potential safety hazards.
-
Short circuit hazard
Unprotected tabs may be punctured, causing internal short circuits of products.
Recommended Product Type
— Selection Guidelines
Select based on battery type (cylindrical/prismatic/pouch), application position (tab/electrode group/casing), and operating temperature requirements.
