Title (EN) LITHIUM SECONDARY CELL
(FR) PILE SECONDAIRE AU LITHIUM
Abstract: front page image
(EN)A lithium secondary cell with a small decrease in discharge capacity during high-load discharge and little self-discharge. The electrolytic layers of the cell consist of positive-side and negative-side polymer electrolytic layers integrated with their respective electrodes, wherein the positive-side electrolytic layer is lower than the negative-side electrolytic layer in direct current resistance.
(FR)L'invention concerne une pile secondaire au lithium présentant une faible diminution de la capacité de décharge pendant une décharge à charge élevée et une décharge naturelle infime. Les couches électrolytiques de la pile consistent en des couches électrolytiques polymères côté positif et côté négatif intégrées à leurs électrodes respectives, la couche électrolytique côté positif étant inférieure à la couche électrolytique côté négatif dans la résistance au courant direct.
