Although Na-ion batteries(NIBs) recently got its resurgence due to its material abundance,low-cost and environmental benignity,the development of a viable anode poses a huge challenge for its commercialization.Graphite,the traditional anode of Li-ion batteries(LIBs),owns practical capacity of about 340 mAh/g or 700 Ah/L,failed to intercalate with any Na+.Hard carbon,with capacity of about 300 mAh/g or 450 Ah/L [1],is therefore has been proposed as an alternative choice of anode for NIBs.
