    Diaphragm with a dense porous structure, which allows it to achieve a more uniform pore distribution which in turn can reduce internal resistance and improve discharge performance of our batteries.

    Ceramic Diaphragm

    The surface-coated nano-ceramic battery separator has the advantages of high temperature resistance, high voltage resistance, high puncture and high liquid absorption, which can greatly improve the heat shrinkage of the diaphragm and improve the safety and reliability of the battery.

    According to UL1642 heating for 30min (hot oven 130°C).

    nano-ceramic battery separator

    Cell opening, no fire, no explosion, weight loss ≤ 10%.

    Ultrathin Diaphragm

    The 9um diaphragm reduces the internal resistance of the battery and increases the volumetric energy density of the battery

    Battery model:GRP574285-S
    Battery size:5.7mm*42mm*85mm
