专利号:WO-2024011371-A1 优先权日:2022-07-11 标题 :Binder for positive electrode plate and synthesis method therefor, positive electrode plate comprising same, secondary battery and electric device 发明人:YE CHONG; SUN CHENGDONG; ZHENG YI; XIE LAIYONG 权利人:CONTEMPORARY AMPEREX TECHNOLOGY CO LTD 摘要:Provided in the present application are a binder for a positive electrode plate and a synthesis method therefor, a positive electrode plate comprising same, a secondary battery and an electric device. The binder comprises a copolymer formed by comonomers, wherein the comonomers comprise a first monomer, a second monomer, a third monomer, and a fourth monomer, and the molar content of the first monomer is 3 mol% to 10 mol% based on the total molar amount 100 mol% of the comonomers. The binder provided in the present application not only has good flexibility and high cohesiveness, but also has good electrolyte swelling resistance, such that a positive electrode plate is ensured to have a high bonding strength and good processing properties, and a secondary battery is also ensured to maintain a good structural stability during the long-term charging and discharging processes, which further gives full play to the electrochemical properties of the secondary battery.
