The Donlee battery tape series, offering premium battery tape solutions, is mainly made of PET, PI, BOPP, or other functional base films, which are coated with specialized pressure-sensitive adhesive by a precision coating machine. The products, including specialized battery terminal tape and battery insulation tape, can be customized in thicknesses, colors, and adhesions in different application scenarios. We offer a wide range of solutions for the battery industry including terminal fixing tape, bonding tape, temperature resistant tape, EV battery wrapping tapes, fireproof and insulation tapes, etc, some other news tapes for battery are constantly developing. The above products are widely applied in Lithium battery as terminal fixing, battery tabs and aluminum case insulation and wrapping, temporary protection for pouch cells during their in-plant processing, etc., with battery insulation tape playing a critical role in safety and performance.
The terminal tapes are made of insulative PET film as substrate and coated with electrolyte-resistant acrylic adhesive specially formulated for lithium battery.
They are designed for fixing and insulative protection of positive and negative electrodes and other parts of lithium batteries. It‘s electrolyte resistance, high adhesion, soft easy and flat to apply. The materials are environmentally green and halogen-free.
The Dynamic Battery Tapes are made of blue dual-layer PET film as substrate, coated with high tack acylic pressure sensitive adhesive. Usually used for wrapping and packing rectangular aluminium cased dynamic power batteries.
Excellent alkali resistance, high tensile strength and fewest deformation rate. They own high performance features in stable self-adhesion, reliable insulation and thermal conductivity, also high temperature resistance, etc.
The Pouch Cell Process Protective Tapes are made of PET/PP as substrates, coated with flexible acrylic adhesive. They are specially designed to protect aluminum-plastic compositive foil- a component of the pouch cell-during the cell’s forming processes.
The tapes have no wrinkles happening after forming completion, no residue under high temperature and pressure, also free from ink transfer or fragments of printed codes.
The Battery Tab Tapes are made of PI (Polyimide) film as the substrates, coated with Electrolyte resistant pressure-sensitive adhesive. Specially designed for tabs protection when they are in steel and aluminum cased batteries, pouch cell, and cylindrical batteries.
The tapes wrap around ultrasonic welded Joints of the tabs to prevent puncturing that avoids short circuits from the battery core.
The tapes are high temperature and electrolyte corrosion resistance and prevent battery or cell’s internal resistance from abnormal raising.
