The performance of the HNMG electrodes with various mass loadings. a Constant current first cycle charge–discharge curves at a rate of 2 C for the HNMG electrodes with a mass loading of 1, 3, and 6 mg cm−2, respectively. b The capacity of the HNMG electrodes with different mass loadings cycled at a rate of 2 C for 500 cycles in the 0.01–2.0 V window (vs. Li/Li+). c Specific capacity of the HNMG electrodes with different mass loadings measured at charge–discharge rate from 0.2 to 40 C. d Areal capacity and e utilization of the active material of the HNMG electrodes with various mass loading at different C rates. The gray area marked in d represents the range of the areal capacity of common commercial anodes. f A comparison of the areal performance metrics of a HNMG electrode with a mass loading of 6 mg cm−2 with representative anodes reported
