Abstract:
A method of manufacturing a lithium-ion secondary battery electrode sheet proposed herein includes the step of pressing granulated particles (13a), wherein the ratio (t/D50) is less than 1, where D50 is the mean particle size of the granulated particles (13a) and t is the thickness of a layer (14) of active material particles (13a1) after pressing.
