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.
Claims2
A method of manufacturing a lithium-ion secondary battery electrode sheet, comprising the steps of:
- preparing a current collector;
- preparing granulated particles containing active material particles and a binder;
- feeding the granulated particles onto the current collector;
- leveling the granulated particles fed on the current collector;
- and
- pressing the leveled granulated particles, wherein
- in the step of feeding the granulated particles, the ratio (t/D50) is less than 1, where D50 is the mean particle size of the granulated particles fed onto the current collector and t is the thickness of a layer of the active material particles that has been formed subsequent to the step of pressing.
