Abstract: front page image
(EN)A positive active material for use in nonaqueous secondary batteries, the positive active material comprising, as the crystalline structure of a main crystalline phase, a lithium-containing transition metal oxide containing manganese. The positive active material contains a minor oxide having the same oxygen arrangement as the lithium-containing transition metal oxide and having a different elemental composition and further contains tin(IV) oxide, the minor oxide and the tin(IV) oxide being contained in such a state that the presence thereof can be ascertained through diffractometry.
(FR)L'invention concerne une matière active positive destinée à être utilisée dans des batteries secondaires non aqueuses. Cette matière active positive comprend, comme structure cristalline de phase cristalline principale, un oxyde de métal de transition à base de lithium contenant du manganèse. La matière active positive contient un oxyde mineur présentant le même agencement d'oxygène que l'oxyde de métal de transition à base de lithium et une composition élémentaire différente, et elle contient également de l'oxyde d'étain (IV), l'état de l'oxyde mineur et de l'oxyde d'étain (IV) permettant de déterminer leur présence par diffractométrie.
(JA) 本発明に係る正極活物質は、主たる結晶相の結晶構造として、マンガンを含有するリチウム含有遷移金属酸化物を含み、非水系二次電池において用いられる正極活物質において、上記リチウム含有遷移金属酸化物と同一の酸素配列を有し、かつ、異なる元素組成である副酸化物および酸化スズ(IV)を含むと共に、回折法によってその存在を確認することができる状態で、上記副酸化物および酸化スズ(IV)を含んでいるものである。
