Electrochemical stability of electrolytes containing LiNO₃ as an additive. (A) Li stripping and plating profiles for Li//Cu electrochemical cells and (B) the corresponding CEs as a function of cycle number at a fixed current density of 1 mA cm⁻² and for a Li plating capacity of 1 mAh cm⁻² per cycle. (C and D) Results from analogous experiments to A and B) except a higher Li plating capacity per cycles (3 mAh cm⁻² at 1 mA cm⁻²) was employed in the measurements. (E and F) Galvanostatic cycling characteristics of high-capacity/high-rate Li half-cells composed of Li//nonplanar (carbon cloth) current collector. The Li plating capacity per cycle is 10 mAh cm⁻² and the current density is 5 mA cm⁻². The profiles for A, C, and E are for the electrolyte previously designated DOL Ele. fortified with 0.5 M LiNO₃.
