Abstract: front page image
(EN)The present invention relates to the manufacture of a high capacity electrode by synthesizing an excellent Li2MnO3-based composite material Li(LixNiyCozMnwO2) with a specific capacity of about 460mAh/g. Here, a manufacturing method of a cathode material for a lithium secondary battery uses a Li2MnO3-based composite material Li(LixNiyCozMnwO2) by mixing a starting material wherein a nickel nitrate solution, a manganese nitrate solution and a cobalt nitrate solution are mixed, with a complex agent by co-precipitation.
(FR)La présente invention porte sur la fabrication d'une électrode haute capacité par synthèse d'une excellente matière composite à base de Li2MnO3 Li(LixNiyCozMnwO2) ayant une capacité spécifique d'environ 460 mAh/g. Ici, un procédé de fabrication d'une matière de cathode pour une batterie secondaire au lithium utilise une matière composite à base de Li2MnO3 Li(LixNiyCozMnwO2) par mélange d'une matière de départ dans laquelle une solution de nitrate de nickel, une solution de nitrate de manganèse et une solution de nitrate de cobalt sont mélangées, avec un agent complexe par co-précipitation.
(KO)본 발명은 이론용량이 약 460mAh/g 수준으로 매우 우수한 Li2MnO3 계 복합소재 Li(LixNiyCozMnwO2)를 합성하여, 이를 이용하여 고용량 전극을 제조하기 위한 것이다. 여기서, 리튬이차전지용 양극 물질 제조방법은 질산 니켈 용액, 질산 망간 용액 및 질산 코발트 용액을 혼합한 출발물질 용액에 착화제를 혼합하여 공침법으로 Li2MnO3 계 복합소재 Li(LixNiyCozMnwO2)를 사용한다.
