Graphene, PVDF (Mw = 600,000, Aladdin, Shanghai, China), LATP and LiClO4 (≥99.5%, Aladdin, Shanghai, China) were vacuum-dried at 60 °C for 24 h. Graphene powder was dissolved in dimethylformamide (DMF, ≥99.9%, Macklin, Shanghai, China) to prepare a 5 g L−1 graphene–DMF solution, stirred at 45 °C for 12 h, then ultrasonically treated for 15 min. A total of 5 g of PVDF powder was dissolved in a 40 mL DMF solution and stirred at 45 °C for 1 h to form a transparent viscous solution. LiClO4 and LATP were introduced and stirred for 6 h. The mass ratio of PVDF, LATP and LiClO4 is 80:8:1. The graphene solutions of different concentrations from 0 wt% to 10 wt% were added and stirred for 12 h. Finally, the PLLG mixed solution was poured into a polytetrafluoroethylene mold and vacuum-dried at 50 °C for 24 h to obtain a PLLG composite solid electrolyte membrane. The membrane was cut into small discs with a diameter of 18 mm and stored in a glove box (argon, O2 < 0.1 ppm, H2O < 0.1 ppm) for the experiment. The preparation process is shown in Figure 1 .

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
