摘要: With an aim to enhance the thermal stability and electrolyte wetting of a polyethylene porous separator, Al2O3 nano-powder layer electro-spun PVdF nanofiber were successively formed on both sides separator. The provides excellent as indicated by shrinkage only 7.8 % in area at 180 °C absence meltdown up 200 °C. uptake multilayer separator was increased with thickness layer. As result, discharge capacity, rate capability, cycle life lithium ion batteries employing layers improved, overcompensating for loss performance caused Therefore, approach is highly effective improving safety batteries.
