Description

technical field

[0001] The invention relates to an electrolyte material, in particular to a carbohydrate-modified lithium-conducting polymer / inorganic hybrid electrolyte and its application in lithium-ion batteries, lithium-sulfur batteries or lithium-air batteries, belonging to the technical field of lithium batteries. Background technique

[0002] Since it was put into the market in 1991, lithium-ion batteries have been widely used in small and medium-sized battery fields such as computers, notebook computers, power tools, and electric bicycles. With the development of large-scale battery applications such as electric vehicles and energy storage, higher requirements are placed on the energy density and safety performance of batteries. Traditional electrolytes are mainly composed of carbonate solutions, which are fluid, flammable, toxic, and explosive, which is an important cause of lithium battery safety problems. It also restricts the structural design of the battery and ...
