Stability of 0.7Li(CB9H10)–0.3Li(CB11H12) with lithium metal. a CV curve of a Mo/0.7Li(CB9H10)–0.3Li(CB11H12)/Li cell at a scan rate of 0.5 mV s−1 and a scan range of −0.1 to 5.0 V (vs. Li+/Li). b Nyquist plot of a Li/0.7Li(CB9H10)–0.3Li(CB11H12)/Li cell. Inset shows the magnified plot in the region of the semicircle indicating the 0.7Li(CB9H10)–0.3Li(CB11H12)/Li interfacial resistance. c FE-SEM image of the 0.7Li(CB9H10)–0.3Li(CB11H12)/Li interface. d 10th galvanostatic cycling profile of the Li/0.7Li(CB9H10)–0.3Li(CB11H12)/Li cell. Inset shows the magnified profile. e Galvanostatic cycling profiles for prolonged cycles. 1st–100th cycles (top), 101st–200th cycles (middle), and 201st–300th cycles (bottom). All electrochemical measurements were conducted at 25 °C. Scale bar, 30 μm in c
