摘要： Disclosed is a binder, which comprises polymer particles obtained by polymerization of: (a) 1˜80 parts by weight of a (meth)acrylic acid ester monomer; (b) 1˜20 parts by weight of an unsaturated carboxylic acid monomer; and (c) 0.001˜40 parts by weight of a vinyl monomer, based on 100 parts by weight of the binder polymer, and which allows electrode active material particles capable of lithium intercalation/deintercalation to be fixed and linked among themselves, and between the particles and a collector. An electrode comprising the binder, and a lithium secondary battery having the electrode are also disclosed. Further, a method for evaluating interrelation between wettability of a binder to an electrolyte and quality of a battery comprising the binder is disclosed. The binder shows excellent adhesion as well as excellent wettability to an electrolyte, and thus can improve rate characteristics and lifespan characteristics of a battery, when used in an electrode for a lithium secondary battery.
摘要翻译：公开了一种粘合剂，其包含聚合物颗粒，所述聚合物颗粒通过聚合得到：（a）1〜80重量份的（甲基）丙烯酸酯单体; （b）1〜20重量份不饱和羧酸单体; 和（c）0.001〜40重量份的乙烯基单体，基于100重量份的粘合剂聚合物，并且其允许能够嵌入/脱嵌的电极活性材料颗粒彼此之间固定并连接颗粒和收集器。还公开了包含该粘合剂的电极和具有该电极的锂二次电池。此外，公开了一种用于评估粘合剂对电解质的润湿性和包含粘合剂的电池质量之间的相互关系的方法。粘合剂对于电解质显示出良好的粘附性和优异的润湿性，因此当用于锂二次电池的电极时，可以提高电池的速率特性和寿命特性。
