摘      要：Solid-state electrolytes(SSEs)are a solution to safety issues related to flammable organic electrolytes for Li *** contact between the anode and SSE results in high interface resistance,thus causing the batteries to exhibit high charging and discharging ***,we reduced the overpotential of Li stripping and plating by introducing a high proportion of dual-conductive phases into a composite *** current study investigates the interface resistance and stability of a composite electrode modified with Zn and a lower proportion of dual-conductive ***-cation-adsorbed Prussian blue is synthesized as an intermediate component for a Zn-modified composite electrode(Li-FeZnNC).The Li-FeZnNC symmetric cell presents a lower interface resistance and overpotential compared with Li-FeNC(without Zn modification)and Li-symmetric *** Li-FeZnNC symmetric cell shows high electrochemical stability during Li stripping and plating at different current densities and high stability for 200 *** batteries with a Li-FeZnNC composite anode,garnet-type SSE,and LiFePO4 cathode show low charging and discharging overpotentials,a capacity of 152 mAh g^(−1),and high stability for 200 cycles.
