Abstract
Cathode for collecting and donating charged particles. The cathode comprises current collector means for collecting charged particles injected into the cathode from an anode. Current conducting means are provided which are electrically interfaced to an ion transporting medium and to the current collector means. The current conductor means transfers charge from the current collector means to the ion transporting medium. The current conducting means comprises a plurality of core members and a charge donor material that donates charge to the ion transporting medium when the current collector means collects charged particles. A battery is also provided comprising the cathode and an anode means for discharging charged particles when the battery is loaded. Methods of manufacturing the cathode comprise coating a plurality of core members with a charge donating material and interfacing the coated core members to an ion transporting medium to provide a subassembly composite. The subassembly composite is interfaced with the current collector. In preferred embodiments, the cathode comprises a matrix of carbon fibers coated with an electrically conductive polymer which are integrally engaged with a polymeric ion transporting medium.
