点から溶媒の流出を防止する保持剤が望まれていた。(Prior art) Conventionally, non-aqueous solvents have been used to prevent static electricity from being generated due to liquid vibration within a container, from causing an explosion risk due to vibration, or from scattering highly toxic substances. A method is known in which the solvent is impregnated into a solid or the like. It has been desired that such a solvent can hold as much liquid as possible per unit weight. Furthermore, in batteries and the like that use non-aqueous solvents, a retention agent that prevents the solvent from flowing out has been desired from the viewpoint of safety.

である。The carbon fiber used in the present invention is a carbon fiber obtained by thermally decomposing a carbonization raw material in the presence of a catalyst, which is a so-called gas phase method. The fibers obtained by the vapor phase method are extremely thin and have excellent electrical conductivity due to their high crystallinity and orientation, and depending on heat treatment, they can develop electrical conductivity close to that of single crystal graphite. A structural feature of this carbon fiber is that layers of graphite or carbon easily converted to graphite are formed in annual ring-like arrangements substantially parallel to the longitudinal axis.
