With batteries being used in so many of our day-to-day products, from cell phones to electric vehicles, battery insulation wrap is becoming more and more important. These wraps surround batteries and protect them from heat and other factors that may be detrimental to the performance of the battery. While this keeps the batteries working better for a longer period, it also keeps users safe by preventing dangerous thermal runaway.
There are various benefits to battery insulation wrap. Let’s explore them here:
Prevents Cell Overheating in Batteries
Cell overheating and thermal runaway in batteries are extremely dangerous and can cause serious harm to the device or even the individuals using the battery. Overheating can result in reduced battery performance and cause permanent damage. If the heat in the battery gets too high, it sets off a chain reaction called thermal runaway. Thermal runaway happens in a matter of seconds and the heat can cause an extremely hot fire to start that is nearly impossible to extinguish.
It is essential to prevent thermal runaway and overheating in battery cells by implementing the proper insulation materials. Battery insulation wrap can isolate the battery cell so that if it is experiencing thermal runaway it will prevent it from spreading to other cells and becoming even more out of control.
Acts as a Dielectric Barrier Between Battery Cells
Dielectric barriers prevent electrical discharges between two electrodes to discourage thermal runaway and overheating. By preventing electrical discharges from occurring between electrodes or individual cells in a battery, the chances of overheating are reduced, thus also reducing the risk of thermal runaway.
Dielectric barriers surround the individual cell batteries, physically blocking off the electrical discharges from jumping to another electrode. Again, since these barriers prevent overheating and thermal runaway, they enhance the safety of the battery and keep consumers safe.
Choose from a Variety of Battery Insulation Wrap Materials
Many different battery insulation wrap materials are available to choose from given the type of battery used, the battery’s application, and any industry requirements. While these are not all of the possibilities, some common battery insulation wrap materials include:
PET is a high-strength material that is resistant to chemicals, has good dimensional stability, low moisture absorption, and good electrical insulation properties. These properties make it ideal for battery insulation, specifically as a dielectric barrier.
Polypropylene, or PP, has various advantageous properties that make it a good battery insulator. It is resistant to chemicals and heat, has good tensile strength, and has low electrical conductivity.
Polyimide has excellent heat resistance, high tensile strength, and good electrical properties. These characteristics are consistent over a wide range of temperatures, both hot and cold, making it a great insulator.
