  • Lithium battery with separator stored lithium
    Publication number: 20020122986
    Abstract: A lithium battery having a separator capable of storing excess lithium ions. As lithium ions are irreversibly adsorbed by the battery electrodes, they are replenished from the excess lithium stored in the separator material, thereby extending battery life. In an example of the present invention, molecular sieves, such as 13X molecular sieves, are used as the separator material. Molecular sieves are hydroscopic and therefore also react with moisture in the battery, thereby reducing cell impedance.
