Fig. 3 (a) Schematic of carbon molecular sieve for N2/O2 separation; (b) Charge-discharge curves at first cycle of graphite, activated carbon and carbon molecular sieve; (c) SAXS patterns of porous carbon (PC) and (d) sieving carbon (SC) anodes before and after (dashed line) five full cycles at a current density of 50 mA/g. Inset: the relative location of the SEI to the nanopores. The SEI is a green irregular shape with yellow solid circles (sodium ions) inside[26]
