The present invention provides a paste electrolyte comprising an organic solvent of not high dielectric constant, soluble lithium salts, and clays, with the clays being swollen by the solvent, and rechargeable lithium batteries containing the paste electrolyte. The paste electrolyte according to the present invention can improve the electrochemical properties and cycling stability of rechargeable lithium batteries by limiting the anionic transport between anode and cathode without significantly decreasing the lithium transport rate, particularly during fast charge and discharge.
La présente invention concerne un électrolyte pâteux comprenant un solvant organique de constante diélectrique non élevée, des sels de lithium solubles, et des argiles, les argiles étant gonflés par le solvant, ainsi que des batteries au lithium rechargeables contenant l'électrolyte pâteux. L'électrolyte pâteux selon la présente invention peut améliorer les propriétés électrochimiques et la stabilité cyclique de batteries au lithium rechargeables par limitation du transport anionique entre une anode et une cathode sans diminuer significativement le taux de transport de lithium, en particulier au cours d'une charge et d'une décharge rapides.
