Method of producing electrode plate filled with active material, method of producing battery using thereof

A production method for a battery, comprising the steps of:

• a) forming a plurality of electrode plates by forming a layer filled with an active material on a main surface of a plate-shaped core body;
• b) layering the plurality of electrode plates formed in the electrode plate forming step;
• c) infiltrating a liquid, which contains a xylene resin and an organic solvent and in which a carbon black is dispersed, to end surfaces of the plurality of layered electrode plates, the organic solvent being selected from a group consisting of xylene, acetone and tetrahydrofuran;
• d) forming an electrode body by arranging a positive electrode plate and a negative electrode plate to face each other with a separator in between, wherein at least one of the positive electrode plate and the negative electrode plate uses an electrode plate made from said at least one electrode plate having been subjected to the liquid infiltrating step and containing the active material;
• and
• e) assembling a battery by housing the electrode body formed in the electrode forming step into an outer container.
