Abstract:
A non-aqueous electrolyte secondary battery comprising:a scrolled body of an anode sheet and a cathode sheet with a pair of separator sheets sandwiched therebetween, said anode sheet being coated with a plurality of regions of anode active material separated by a plurality of slit-shaped space regions elongating in a width direction of said anode sheet, wherein each of said slit-shaped space regions is disposed so that an adjacent distance becomes narrower towards a center of said scrolled body, said cathode sheet being coated with cathode active material; a container housing said scrolled body and having anode and cathode terminals electrically connected to said anode and cathode sheets, respectively; and an organic non-aqueous electrolyte filling said scrolled body within said container such that said anode active materials are impregnated with said electrolyte through said slit-shaped space regions.
