Title (EN) POSITIVE ELECTRODE ACTIVE MATERIAL FOR POTASSIUM ION SECONDARY CELL
(FR) MATÉRIAU ACTIF D'ÉLECTRODE POSITIVE POUR PILE RECHARGEABLE POTASSIUM-ION
(JA) カリウムイオン二次電池用正極活物質
Abstract:
(EN) In the present invention, by employing a positive electrode active material for a potassium ion secondary cell containing a potassium compound represented by general formula (1): KnMOm (where M represents copper or iron, n represents 0.5 to 3.5, and m represents 1.5 to 2.5), a positive electrode active material for a potassium ion secondary cell is provided which has higher theoretical discharge capacity and effective capacitance than a potassium secondary cell in which Prussian blue is used as the positive electrode active material.
(FR) Dans la présente invention, par utilisation d'un matériau actif d'électrode positive pour pile rechargeable potassium-ion contenant un composé de potassium représenté par la formule générale (1) : KnMOm (dans laquelle M représente le cuivre ou le fer, n est compris entre 0,5 et 3,5, et m est compris entre 1,5 et 2,5), un matériau actif d'électrode positive pour pile rechargeable potassium-ion est obtenu qui présente une capacité de décharge théorique et une capacité effective plus grandes que celles d'une pile rechargeable au potassium dans laquelle du bleu de Prusse est utilisé comme matériau actif d'électrode positive.
(JA) 一般式(1):KMO[式中、Mは銅又は鉄を示す。nは0.5~3.5を示す。mは1.5~2.5を示す。]で表されるカリウム化合物を含有するカリウムイオン二次電池用正極活物質を採用することで、Prussian blueを正極活物質として用いたカリウム二次電池よりも高い理論充放電容量又は実効容量を有するカリウムイオン二次電池用正極活物質を提供する。
