锂离子电池用P(PETMA)/P(VDF-HFP)基凝胶聚合物电解质
Gel polymer electrolyte for lithium-ion batteries based on P(PETMA)/P(VDF-HFP)
摘要
Abstract
Using pentaerythdtol and methylacrylic acid as raw materials,an unsaturated carboxylic ether monomer with star-shaped structure was synthesized.By blending monomer with P(VDF-HFP) and in-situ thermal polymerization,gel polymer electrolytes and polymer Li-ion cells were prepared,and their properties were studied with FTIR,cyclic voltammogram,XRD and A.C impedance.The results show that this polymer electrolyte exhibits good stickiness and a small consumption of monomer.Its ionic conductivity at room temperature is 1.03 mS/cm,and electrochemical window reaches 5.2 V.The polymer Li-ion cell appears small interface impedance and good discharging performance.关键词
