Electrochemical performances of two-dimensional Si-based nanosheet electrode in the ionic electrolyte using EMI-TFSI as the media. (a) CV curves at the scan rate of 1000 mV s^-1 with the cell voltage ranging 2.0 to 4.0 V. (b) CV curves at different scan rates from 10 to 100 mV s^-1. (c) CV curves at different scan rates from 200 to 2000 mV s^-1. (d) CV curves at various scan rates from 5000 to 50000 mV s^-1. (e) GCD curves at various current densities from 0.2 to 10 A g^-1. (f) Cycling stability over 12000 charging/discharging process at 2 A g^-1. Reproduced with permission from Ref. [71]. Copyright 2020, Wiley-VCH.
