Abstract:
(EN) The purpose of the present invention is to provide a non-aqueous secondary cell having exceptional charge/discharge cycle characteristics at a high voltage, a non-aqueous electrolyte used in the non-aqueous secondary cell, and a method for manufacturing the non-aqueous secondary cell. This non-aqueous secondary cell comprises a positive electrode, a negative electrode, and a non-aqueous electrolyte. When the positive electrode, after charging is performed to 4.5 V with a 1/3 C current and then discharging is performed to 3 V with a 1/3 C current, is cleaned with methyl ethyl carbonate and then vacuum dried, and then the surface of the positive electrode is analyzed by X-ray photoelectron spectroscopy, Rf/Ro is 0.05-1.3 inclusive, or Rc/Ro is 0.05-0.75 inclusive, where Ro (atom%) represents the proportion of oxygen atoms, Rf (atom%) represents the proportion of fluorine atoms, and Rc (atom%) represents the proportion of carbon atoms in which the binding energy of the 1s orbit is 289-291 eV, said atoms being contained at the surface of the positive electrode.
(FR) Le but de la présente invention est de pourvoir à une pile rechargeable à électrolyte non aqueux présentant des caractéristiques de cycle de charge/décharge exceptionnelles à une tension élevée, à un électrolyte non aqueux utilisé dans la pile rechargeable à électrolyte non aqueux, et à un procédé de fabrication de la pile rechargeable à électrolyte non aqueux. Cette pile rechargeable à électrolyte non aqueux comprend une électrode positive, une électrode négative et un électrolyte non aqueux. Lorsqu'on nettoie l'électrode positive, après avoir effectué une charge jusqu'à 4,5 V avec un courant de 1/3 C puis une décharge jusqu'à 3 V avec un courant de 1/3 C, avec du carbonate d'éthyle méthyle puis qu'on la sèche sous vide, et qu'on analyse ensuite la surface de l'électrode positive par spectroscopie photoélectronique à rayons X, Rf/Ro est compris entre 0,05 et 1,3 inclus, ou Rc/Ro est compris entre 0,05 et 0,75 inclus, Ro (% atomique) représentant la proportion d'atomes d'oxygène, Rf (% atomique) représentant la proportion d'atomes de fluor, et Rc (% atomique) représentant la proportion d'atomes de carbone dans lesquels l'énergie de liaison de l'orbite 1s est de 289 à 291 eV, lesdits atomes étant contenus à la surface de l'électrode positive.
(JA) 本発明は、高電圧での充放電サイクル特性に優れた非水二次電池及びそれに用いる非水電解液、並びにその非水二次電池の製造方法を提供することを目的とする。本発明の非水二次電池は、正極、負極及び非水電解液を備え、1/3Cの電流で4.5Vまで充電した後、1/3Cの電流で3Vまで放電した後の前記正極を、メチルエチルカーボネートで洗浄した後に真空乾燥し、その後、前記正極の表面をX線光電子分光分析法で分析した場合、前記正極の表面における、酸素原子の含有割合をRo(原子%)、フッ素原子の含有割合をRf(原子%)、1s軌道の結合エネルギーが289~291eVの炭素原子の含有割合をRc(原子%)とすると、Rf/Roが0.05以上1.3以下であるか、又はRc/Roが0.05以上0.75以下である。
