Carbon Fiber Reinforced LiFePO4-Based Three-Dimensional Bulk Electrodes with Metal-Current-Collector- and Binder-Free Design
- 1 Downloads
Conductive hierarchically porous LiFePO4 blocks enhanced by carbon fiber were successfully obtained, which is benefited from nice sinter-activity of hydrothermal synthesized LiFePO4. In combination with hierarchically porous and carbon-fiber-reinforced electric-conductive topologies, metal-current-collector- and binder-free design, the as-prepared bulk electrodes present excellent rate capability and cycle life. Our proofof- concept study on LiFePO4-based bulk electrodes shows facile approach to improve energy density and lower cost of Li-ion batteries.
