Description

technical field [0001] The invention relates to a preparation method of an ionic liquid gel electrolyte, in particular to a preparation method of a supramolecular ionic liquid gel electrolyte and its application in a sodium ion battery. Background technique [0002] As the application of lithium-ion batteries expands to electric vehicles and rechargeable and dischargeable fixed storage devices, the global lithium supply is gradually in short supply and the price is rising. It is urgent to seek alternatives to lithium-ion batteries. In the earth's surface and crust, the content of sodium element is higher than that of lithium element, and sodium-ion battery and lithium-ion battery have electrochemical similarities, which makes sodium-ion battery gradually become a research hotspot. However, since the research on Na-based chemistry is far less than that on Li-based chemistry, the performance of Na-ion batteries is far from optimal, and further research on electrode and electro...
