Abstract:
(EN) According to the present invention, a positive electrode is provided with a positive electrode collector and a positive electrode mixture layer that is formed on the collector. The positive electrode mixture layer comprises: a lithium transition metal composite oxide that contains 50% by mole or more of Ni relative to the total number of moles of metal elements excluding Li; a carbon material that has electrical conductivity; and an adhesion improving material that adheres to the lithium transition metal composite oxide and the carbon material. The adhesion improving material has a Lewis acidic group, a Lewis basic group, and a hydrophobic group containing an aromatic ring.
(FR) La présente invention concerne une électrode positive pourvue d'un collecteur d'électrode positive et d'une couche de mélange d'électrode positive qui est formée sur le collecteur. La couche de mélange d'électrode positive comprend : un oxyde composite de lithium-métal de transition qui contient au moins 50 % en mole de Ni par rapport au nombre total de moles d'éléments métalliques, le Li étant non compris ; un matériau de carbone électro-conducteur ; et un matériau d'amélioration d'adhérence qui adhère à l'oxyde composite de lithium-métal de transition et au matériau de carbone. Le matériau améliorant l'adhérence possède un groupe acide de Lewis, un groupe basique de Lewis et un groupe hydrophobe contenant un noyau aromatique.
(JA) 正極は、正極集電体と、集電体上に形成された正極合材層とを備える。正極合材層は、Liを除く金属元素の総モル数に対して50モル%以上のNiを含有するリチウム遷移金属複合酸化物と、導電性を有する炭素材料と、リチウム遷移金属複合酸化物と炭素材料に付着する密着性改善材とを有する。密着性改善材は、ルイス酸性基、ルイス塩基性基、及び芳香環を含む疎水性基を有する。
