Abstract:
(EN) A secondary cell is provided with a positive electrode, a negative electrode, and an electrolyte. The positive electrode contains a lithium-containing compound represented by LixCoyNizM1-y-zOb-aXa (where M is aluminum, etc., X is fluorine, etc., 0.8 < x ≤ 1.2, 0 ≤ y ≤ 1, 0.5 ≤ z ≤ 1, 0 ≤ a ≤ 1, 1.8 ≤ b ≤ 2.2, and y < z). The electrolyte contains a solvent, said solvent containing ethylene carbonate and a nitryl compound represented by R1–(CN)n (where R1 is an n-valent hydrocarbon group, and n is an integer of 1 or greater). The ethylene carbonate content in the solvent is 8-20% by weight.
(FR) La présente invention porte sur un élément secondaire comportant une électrode positive, une électrode négative et un électrolyte. L'électrode positive contient un composé contenant du lithium représenté par LixCoyNizM1-y-zOb-aXa (M étant de l'aluminium, etc., X étant de la fluorine, etc., 0.8 < x ≤ 1.2, 0 ≤ y ≤ 1, 0.5 ≤ z ≤ 1, 0 ≤ a ≤ 1, 1.8 ≤ b ≤ 2.2, et y < z). L'électrolyte contient un solvant, ledit solvant contenant du carbonate d'éthylène et un composé nitryle représenté par R1–(CN)n (R1 étant un groupe hydrocarbure à valence n, et n étant un entier supérieur ou égal à 1). La teneur en carbonate d'éthylène dans le solvant est de 8 à 20 % en masse.
(JA) 二次電池は、正極と負極と電解液とを備える。正極は、Lix Coy Niz 1-y-z b-a a (Mはアルミニウムなど、Xはフッ素など、0.8<x≦1.2、0≦y≦1、0.5≦z≦1、0≦a≦1、1.8≦b≦2.2、y<zである。)で表されるリチウム含有化合物を含む。電解液は、溶媒を含み、その溶媒は、炭酸エチレンとR1-(CN)n (R1はn価の炭化水素基、nは1以上の整数である。)で表されるニトリル化合物とを含む。溶媒中における炭酸エチレンの含有量は、8重量%以上20重量%以下である。
