Resumo

A material based on graphene oxide is considered as a desiccant of aprotic solvents in nonaqueous electrolytes containing lithium salts. Three methods are proposed for preparation of final materials with different number and volume of pores. The effect of the initial parameters of hydrogel such as its pH and the concentration of solid substance is studied. Dependences of the adsorption capacity of desiccant on its porosity are plotted. The prospects of this new desiccant in dehydration of lithium electrolytes are discussed as compared with commercial molecular sieves.
