Original Abstract Submitted

The method of the present disclosure for producing a lithium-ion battery includes providing a positive electrode precursor layer containing at least lithium alloy particles and a positive electrode active material, obtaining a lithium-ion battery precursor having the positive electrode precursor layer, the separator layer, and the negative electrode active material layer in an order of the positive electrode precursor layer, the separator layer, and the negative electrode active material layer and impregnated with an electrolyte solution, and performing initial charging on the lithium-ion battery precursor to make the positive electrode precursor layer a positive electrode active material layer, wherein the lithium alloy particle is a lithium alloy particle with a lithium-alloying potential of 0.5 V (vsLi/Li) or higher, and with a particle diameter D90 smaller than 70 μm as measured by a laser diffraction and scattering method.
