Kapton Tape for Lithium Batteries | High Temperature Insulation Solution
Kapton Tape for Lithium Batteries: Critical Insulation for Safety and Performance
In lithium battery manufacturing, insulation is not just a technical requirement — it is a safety necessity.
Kapton (polyimide) tape is widely used in battery assembly due to its ability to withstand heat, prevent short circuits, and maintain long-term stability.
• Internal short circuits
• Thermal runaway risks
• Cell damage and failure
• Safety hazards during operation
