Abstract:
(EN) [Problem] To provide a positive electrode active material with which storage characteristics can be improved without compromising charge-discharge capacity. [Solution] The present invention provides a lithium-nickel-containing composite oxide which has a layered-rock-salt type crystal structure and a ratio of at least 1.2 between the peak strengths attributed to (103) plane and (104) plane as determined by an X-ray powder diffraction technique using Cu-Kα ray as an X-ray source, and which is obtained by: mixing lithium-nickel-containing composite oxide particles having a layered-rock-salt type crystal structure, a lithium compound, and an alkali metal compound; baking the mixture at a temperature of 800-1000°C; washing and removing all alkali metals other than lithium; mixing the resultant product with the lithium compound once again; and baking the mixture at a temperature of 600-800°C.
(FR) Le problème à la base de l'invention concerne un matériau actif d'électrode positive qui permet d'améliorer les caractéristiques de stockage sans compromettre la capacité de charge-décharge. La solution de la présente invention porte sur un oxyde composite contenant du lithium-nickel qui présente une structure cristalline de type sel gemme stratifié et un rapport d'au moins 1,2 entre les intensités de pic attribuées au plan (103) et au plan (104), telles que déterminées par une technique de diffraction des rayons X sur poudre à l'aide du rayon Cu-Kα en tant que source de rayons X et qui est obtenu par : mélange de particules d'oxyde composite contenant du lithium-nickel présentant une structure cristalline de type sel gemme stratifié, d'un composé de lithium et d'un composé de métal alcalin ; cuisson du mélange à une température de 800-1000°C ; lavage et élimination de tous les métaux alcalins autres que le lithium ; nouveau mélange du produit résultant avec le composé de lithium ; et cuisson du mélange à une température de 600 à 800°C.
(JA) 【課題】充放電容量を損ねることなく、保存特性を改善可能な正極活物質を提供する。 【解決手段】層状岩塩型の結晶構造を備える、リチウムニッケル含有複合酸化物粒子と、リチウム化合物と、アルカリ金属化合物とを混合して、800℃~1000℃の範囲の温度で焼成し、前記リチウム以外のアルカリ金属を洗浄して除去し、再度、リチウム化合物と混合し、酸化性雰囲気下にて、600℃~800℃の範囲の温度で焼成することにより、層状岩塩型の結晶構造を備え、X線源としてCu-Kα線を用いたX線粉末回折から得られる(003)面と(104)面に帰属するピーク強度の比が1.2以上である、リチウムニッケル含有複合酸化物を得る。
