NASICON-type Li[Formula: see text]Al[Formula: see text]Ti[Formula: see text](PO[Formula: see text] (LATP) solid electrolytes have been widely studied because of its stability in the air, low material price and high ionic conductivity. Gd-doped Li[Formula: see text]Al[Formula: see text]Gd[Formula: see text]Ti[Formula: see text](PO[Formula: see text] ([Formula: see text]= 0, 0.025, 0.05, 0.075 and 0.1) with high ionic conductivity was successfully synthesized by solvothermal method for the first time in this work. The effect of Gd doping content on the structure and electrochemical performance of solid electrolytes was systematically studied. The optimal doping content of Gd is [Formula: see text]= 0.075. With the Gd doping content of 0.075, the solid electrolyte has the highest ionic conductivity of 4.23 × 10[Formula: see text] S cm[Formula: see text] at room temperature, the lowest activation energy of 0.247 eV and the highest relative density of 94.89%. This is because the fact that when [Formula: see text]= 0.075, it is the maximum content of Gd[Formula: see text] to replace Al[Formula: see text] and can completely enter the lattice of LATP, and does not emerge too much non-lithium ion conductive GdPO4 phase.

AbstractLi-ion-conducting chloride solid electrolytes receive considerable attention due to their physicochemical characteristics such as high ionic conductivity, deformability and oxidative stability. However, the raw materials are expensive, and large-scale use of this class of inorganic superionic conductors seems unlikely. Here, a cost-effective chloride solid electrolyte, Li2ZrCl6, is reported. Its raw materials are several orders of magnitude cheaper than those for the state-of-the-art chloride solid electrolytes, but high ionic conductivity (0.81 mS cm–1 at room temperature), deformability, and compatibility with 4V-class cathodes are still simultaneously achieved in Li2ZrCl6. Moreover, Li2ZrCl6 demonstrates a humidity tolerance with no sign of moisture uptake or conductivity degradation after exposure to an atmosphere with 5% relative humidity. By combining Li2ZrCl6 with the Li-In anode and the single-crystal LiNi0.8Mn0.1Co0.1O2 cathode, we report a room-temperature all-solid-state cell with a stable specific capacity of about 150 mAh g–1 for 200 cycles at 200 mA g–1.
