Figure 3. CV tests of V$$ _4 $$C$$ _3 $$T$$ _z $$ film electrodes in a 17.5 m LiBr electrolyte, a half-cell setup and a -0.7 to 0.8 V vs. Ag electrochemical window. (A) CV at 10 mV s^-1 (step 2), (B) CV at 0.5 mV s^-1 (step 4) and (C) CV at 0.5 mV s^-1 (step 7). The arrows indicate currents at specified potentials or potential ranges from cycle 1 to cycle n. No activation was performed in this electrode (10 mV s^-1 for 25 cycles, step 6).
