摘要: A thermally stable and flame-retardant separator is proposed to improve the safety of lithium ion batteries. The prepared by dip-coating both sides a conventional tri-layer polyolefin with brominated poly(2,6-dimethyl-1,4-phenylene oxide) (BPPO). Significantly reduced thermal shrinkage flammability are exhibited without decreases in pore size or porosity separator. By using BPPO-coated separator, an electrochemical half-cell composed metal anode LiCoO2 cathode successively tested. resulting cycle performances demonstrated. It expected that can be capable candidate as for safe
