Is it necessary to add water to prepare molybdenum disulfide by liquid phase stripping?

Is the gas phase preparation method or liquid phase preparation method of solid electrode/electrolyte material better? In this paper, the composite material of molybdenum disulfide and polyoxyethylene or graphene oxide was prepared by liquid phase stripping method, and its electrochemical performance was tested as the anode material of lithium ion battery.

Cyclic voltammetry, charge-discharge and rate performance analysis show that
