Abstract
This study achieved efficient preparation of polyanionic single ion conductors by selecting appropriate raw materials and controlling preparation conditions. The results show that the window stability of electrolytic gel with a wide ionic electrochemical conductor is 2-4.5 V and 0.74 lithium ion migration. Lithium iron phosphate battery (LFP) is the positive electrode, lithium metal is the negative electrode, and PVDF-HFP Pampsli ion is the electrolyte. When lithium salt is not added, the rated power of the battery is 125 mah·g-1, and the current density is 2 C. The battery has a range of more than 500 times. In the current high-density 5 C situation, it has a specific capacity of 100 mAh·g-1 and a stable cycling ability of over 300 cycles, while maintaining nearly 100% stable Colomb efficiency.
