NOVELTY - Activating substance for three dimensional batteries, which has filled in particles or a moulding of an activating substance releasing electrons into electrolyte solution in one of the two containers connected via an ion passing material upon charging with electricity.    USE - The activating material is used in three dimensional batteries.    ADVANTAGE - The material has improved hydrophilic properties.    DETAILED DESCRIPTION - Activating substance for three dimensional batteries, which comprises filled in particles or a moulding of an activating substance releasing electrons into the electrolyte solution in one of the two containers. The two containers are connected via an ion passing materials upon charging with electricity and the other container is filled with a moulding or particles of an activating substance which absorb the electrons in the electrolyte solution and an electricity collecting material in contact with the active substance. The collecting material is obtained by adding conductive filler into a powder of an active substance and then moulding and curing the resin into granules, plates or sticks.    INDEPENDENT CLAIMS are also included for:    (1) preparation of the activating substances;    (2) a moulding of an activating substance obtained by forming a primary moulding of the resin and then forming a secondary moulding;    (3) a similar preparation wherein a filler and resin are added into the powder and then a primary moulding is formed, a secondary moulding is formed by pressing and/or adding resin into the primary moulding;    (4) an activating substance in which an inorganic oxide and inorganic hydroxide is added or coated on the moulding;    (5) a method of rendering hydrophilic properties to battery activating substance by coating an inorganic oxide and inorganic hydroxide onto the moulding;    (6) a similar method to (5) wherein the inorganic oxide or hydroxide is added into the moulding;    (7) an activating substance which has high activating power after hydrogen treatment to form small pores; and    (8) an activating method by injecting air under pressure to form small pores on the moulding.
