  • Non-aqueous lithium cells
    Patent number: 5714279
    Abstract: The high discharge rate performance of a non-aqueous lithium electrochemi cell is improved by dispersing a portion of the lithium conducting salt of the electrolyte uniformly throughout the carbon current collector of the cathode in the form of microcrystals. Upon contact, the electrolyte solubilizes the lithium salt from the carbon current collector, increasing the surface area and thus the efficiency of the carbon current collector.
