본 발명은 리튬 이온 배터리용 전극 코팅에 관한 것이며, 이러한 전극 코팅은 70 중량% 초과의 비닐-관능성 환형 카르보네이트와, 아크릴산 및 이의 유도체로 이루어진 군으로부터 선택되는 하나 이상의 단량체의 중합에 의해 제조되는 공중합체 C를 함유하거나, 또는 이의 염을 함유하며, 비닐-관능성 환형 카르보네이트의 중량 비율은 사용되는 모든 단량체들의 중량을 기준으로 5% 내지 90%이다. The invention relates to an electrode coating for a lithium-ion battery, containing copolymer C or the salt thereof, copolymer C being synthesized by polymerizing a combined total of more than 70 wt % of vinyl-functional cyclic carbonate and one or more monomers from the group comprising acrylic acid and the derivatives thereof, the percentage by weight of vinyl-functional cyclic carbonate in relation to the weight of all monomers used being 5-90%.
