Electrochemical cell having a surface modified electrode and associated fabrication process

摘要

An electrode for use in an electrochemical cell comprising a current collecting substrate, an active material associated with the substrate; and a surface modifying component applied to at least a portion of the active material, wherein the surface modifying component is fabricated from at least one of the group consisting essentially of lithium niobates and lithium tantalates. ;A process for manufacturing an electrochemical cell comprising the steps of associating a surface modifying component with an active material, modifying the surface of the active material, fabricating a first electrode by applying the surface modified active material to a current collecting substrate, fabricating a second electrode, and associating at least one electrolyte with the first and second electrodes.
