Abstract
本發明是一種應用於二次電池中，作為正極與負極材料中間隔離膜構造的交聯膠態複合電解質膜，係由交聯聚丙烯(PAN)膠態電解質、聚偏二氟乙烯(PVdF)高分子、與液態電解液組合而成，其中，交聯PAN電解質以AN單體及具有兩個末端丙烯酸酯官能基之交聯劑單體經共聚合而成；聚偏二氟乙烯高分子均聚物，可為PVdF含量80%以上的聚偏二氟乙烯-六氟丙烯共聚物；液態電解液則是使用非水性溶劑，溶解鹼金族或鹼土族金屬鹽類而形成，本發明具有：在高溫下優越之導電度與機械強度、與正負極板貼合性佳、深具工業化潛力等特點。
The present invention is a crosslinked colloid compound electrolysis protoplasmic membrane used for an isolated membrane between anode and cathode, which is composed of PAN polymer electrolyte membrane, PVdF polymer and liquid electrolyte. Wherein, crosslinked PAN polymer electrolyte is polymerized from AN monomer and crosslinked monomer with two PANs on the end; PVdF homopolymer is PVdF-co-HFP copolymer with 80% PVdF; and liquid electrolyte is nonaqueous solvent composed of solving metals of alkaline or alkaline earth metal. The present invention has characteristics of excellent conductivity and mechanical intensity and well paste property with anode and cathode board and industrial potential.
