Sodium-ion batteries(SIBs)are expected to offer affordability and high energy density for large-scale energy storage ***,the commercial application of SIBs is hurdled by low initial coulombic efficiency(ICE),continuous Na loss during long-term operation,and low sodium-content of cathode *** this scenario,presodiation strategy by introducing an external sodium reservoir has been rationally proposed,which could supplement additional sodium ions into the system and thereby markedly improve both the cycling performance and energy density of *** this review,the significance of presodiation is initially introduced,followed by comprehensive interpretation on technological properties,underlying principles,and associated approaches,as well as our perspectives on present inferiorities and future research ***,this contribution outlines a distinct pathway towards the presodiation methodology,of significance but still in its nascent phase,which may inspire the targeted guidelines to explore new chemistry in this field.

The low initial Coulombic efficiency(ICE)is a significant problem hindering the practical uses of carbon anodes in sodium-ion batteries(SIBs),especially for the carbons with large surface *** is an effective way to solve the above problem,but it always needs complicated operations and cannot suppress the unavoidable electrolyte decomposition in the assembled ***,we develop an ultrafast chemical presodiation method for reduced graphene oxide(rGO)using sodium naphthalene(Na-Nt)dissolved in dimethoxyethane(DME)solvent as a presodiation *** presodiation effectively improves the ICE of rGO to 96.8%and forms an artificial solid electrolyte interphase(SEI)on its surface due to the decomposition of the formed complex between Na+and *** formed artificial SEI suppresses the excessive decomposition of electrolytes in the assembled battery,leading to a formation of uniform and inorganic component–rich SEI on rGO surface,which enables a rapid interfacial ion ***,the presodiated rGO showed excellent rate performance with a high capacity of 198.5 mAh g^(-1) at 5 A g^(-1).Moreover,excellent cycle stability indicated by the high capacity retention of 68.4%over 1000 cycles was also achieved,showing the poten-tial to promote the practical uses of high-rate rGO anode in SIBs.

Rechargeable sodium metal batteries(SMBs)have emerged as promising alternatives to commercial Li-ion batteries because of the natural abundance and low cost of sodium ***,the overuse of metallic sodium in conventional SMBs limits their energy densities and leads to severe safety ***,we propose a sodium-free-anode SMB(SFA-SMB)configuration consisting of a sodium-rich Na superionic conductor-structured cathode and a bare Al/C current collector to address the above *** Na_(3)V_(2)(PO_(4))_(3)in the form of Na_(5)V_(2)(PO_(4))_(3)was investigated as a cathode to provide a stable and controllable sodium source in the *** provides not only remarkable Coulombic efficiencies of Na plating/stripping cycles but also a highly reversible three-electron redox reaction within 1.0–3.8 V versus Na/Na+confirmed by structural/electrochemical ***,an ultrahigh energy density of 400 Wh kg^(-1)was achieved for the SFA-SMB with fast Na storage kinetics and impressive capacity retention of 93%after 130 cycles.A narrowed voltage window(3.0–3.8 V ***/Na+)further increased the lifespan to over 300 cycles with a high retained specific energy of 320 Wh kg^(-1).Therefore,the proposed SFA-SMB configuration opens a new avenue for fabricating next-generation batteries with high energy densities and long lifetimes.
