Figure 3. Electrochemical performance of symmetric cells with Li/LM-W10/CF and Li/LM/CF. (A and B) the current densities were controlled to be 0.5 and 1 mA/cm² (The inset were enlarged time-voltage curves); (C) nucleation over-potentials for lithiation in the three electrodes model cell at ~ 1 mA/cm²; (D) rate performance of Li/LM-W10/CF from 0.2 to 1 mA/cm² (2 mAh/cm² pre-deposited Li).
