Patent

CA 2290568

The cycling stability and capacity of Li-ion rechargeable batteries are improved, particularly in an elevated temperature range of about 55 ~C, by the use of lithium aluminum manganese oxy-fluoride electrode components having the general formula, Li1+xAlyMn2-x-yO4-zFz, where x 0.4, 0.1 y 0.3, and 0.05 z 0.5.

La stabilité de cycle et la capacité de piles rechargeables sont améliorées, en particulier dans une plage de températures élevées d'environ 55 ·C, grâce à l'utilisation de constituants d'électrode qui sont des oxy-fluorures de lithium, aluminium et manganèse de formule générale Li¿1+x?Al¿y?Mn¿2-x-y?O¿4-z?F¿z?, dans laquelle x ? 0,4, 0,1 ? y ? 0,3 et 0,05 ? z ? 0,5.
