Future Production Technology for Battery Electrode

摘要

As an example for developing an original design for the battery electrode, which may be essential to produce a unique battery to be needed in the future, a new idea has been introduced. In this idea, polystyrene beads arranged methodically (opal structure) are filled with sol which becomes lithium-ion conductive material (Li{sub}0.35La{sub}0.55TiO{sub}3) by heat treatment, and then the sol is gelatinized to form a polystyrene/ceramics gel composite. When the composite is heat-treated, a lithium-ion conductive porous material is formed. When this material is filled with sol which becomes LiMn{sub}2O{sub}4 by heat treatment, and then the sol is gelatinized, a composite made of the lithium-ion conductive material and the battery active material is formed. The positive electrode and the negative electrode made in this way can then be combined with solid electrolyte to form a solid battery.
