摘要：以2-丙烯酰胺基-2-甲基丙磺酸(AMPS)为反应型乳化剂,丙烯酸丁酯(BA)、丙烯腈(AN)和丙烯酸(AA)为单体,利用互穿网络技术通过乳液聚合法制备了环境友好型聚合物电解质膜(M-ABAA),采用FTIR、XPS、SEM、TEM和TG对M-ABAA进行了表征;通过CV、EIS和充放电测试考察以M-ABAA为电解质膜组装的CR2032电池的电化学性能。结果表明,当m(AMPS)∶m(BA)∶m(AA)∶m(AN)=1∶3∶2∶2时,制备的M-ABAA(M2)的离子电导率为0.98 mS/cm,抗拉强度为7.53 MPa,断裂伸长率为90.4%,吸液率为150%,热收缩率为4%。M2与目前锂离子电池主流的正负极材料(LiCoO_(2)、LiMn_(2)O_(4)、LiFePO_(4)、NCM811)具有较好的相容性,普适性较好。以M2为电解质隔膜,金属锂为负极,分别以LiCoO_(2)和石墨为正极组装成半电池,0.2 C倍率下的首次放电比容量分别为141.3和347.1 mA·h/g,100圈循环后容量保持率分别为94.8%和85.0%;2.0 C倍率下,放电比容量分别为119.8和239.0 mA·h/g。
Environmental-friendly polymer electrolyte membrane(M-ABAA)was prepared from emulsion polymerization of butyl acrylate(BA),acrylonitrile(AN)and acrylic acid(AA)with 2-acrylamide-2-methylpropanesulfonic acid(AMPS)as reactive emulsifier via interpenetrating network technology,and characterized by FTIR,XPS,SEM,TEM and TG.The electrochemical performance of CR2032 battery with M-ABAA as electrolyte membrane was evaluated by CV,EIS and charge and discharge tests.The results showed that the M-ABAA(M2)prepared with m(AMPS)∶m(BA)∶m(AA)∶m(AN)of 1∶3∶2∶2 exhibited an ionic conductivity of 0.98 mS/cm,mechanical strength of 7.53 MPa,elongation break of 90.4%,electrolyte uptake of 150%,and thermal shrinkage of 4%.Meanwhile,the M2 showed good compatibility and universality with the current mainstream anode and cathode materials(LiCoO_(2),LiMn_(2)O_(4),LiFePO_(4),NCM811)used in lithium-ion batteries.With M2 as electrolyte separator,lithium metal as anode electrode,LiCoO_(2)and graphite as cathode electrode,the initial discharge specific capacities were 141.3 and 347.1 mA·h/g,respectively,and the capacity retention rates after 100 cycles were 94.8%and 85.0%,respectively.At 2.0 C rate,the corresponding specific discharge capacities were 119.8 and 239.0 mA·h/g,respectively.
