Fig. 4. The cycling behavior of cells with constant current or pulse current at a high current density of 3 mA cm−2.
(A) Voltage-time and current-time profiles of Li/Li symmetrical cells cycled with constant current. (B) Voltage-time and current-time profiles of Li/Li symmetrical cells cycled with pulsed current (Ton/Toff = 1:5; Ton = 1 s). (C and D) Enlarged views of the dashed rectangular area in (A) and (B), respectively. (E and F) Enlarged views of the rectangular area in (C) and (D), respectively.
