Figure 4: Varying reactivation schemes via controllable C rate.

(a) The capacity retention of the as-prepared anode at a constant rate of 0.45, 1.12, 1.69 or 2.81 C. (b) Comparison of various C-rate schemes for lithiation-induced reactivation process. (c) Long cycling performance at a high rate of 5.62 C after MC-rate reactivation process.
