Characterization of pre-lithiation of c-SiRH and graphite composite with different c-SiRH and graphite mass ratios. a Voltage profiles during the pre-lithiation when 100Ω is integrated. b External short circuit current changes during pre-lithiation. c The first cycle voltage profiles after 6 min of pre-lithiation. d Comparison of the initial Coulombic efficiencies before and after pre-lithiation
