Advanced Lithium Battery Cathodes Using Dispersed Carbon Fibers as the Current Collector
To fabricate LiFePO4 battery cathodes, highly conductive carbon fibers of 10-20 m in diameter have been used to replace a conventional aluminum (Al) foil current collector. This disperses the current collector throughout the cathode sheet and increases the contact area with the LiFePO4 (LFP) particl...
