Figure 5. Electrochemical performance of Li|LiFePO₄ cells. (A) Cycle life of Li|LiFePO₄ with PP and AuPP at 1 C. The amount of 1 mA h cm^-2 of lithium is pre-deposited on the AuPP and Cu, respectively. (B) Voltage profile of different cycles of Li|LiFePO₄ cells with and without Au modified-separators at 1 C. (C) Rate performance of cells with PP and AuPP at the current density of 0.5, 1, 2, 5 and 0.5 C. (D) Voltage profile of cells with AuPP at different current density.
