Abstract
A method for manufacturing a secondary battery determines the amount of the non-aqueous electrolyte to be injected into the bound cell case on the basis of an amount of air space in a positive electrode active material layer, a swelling rate of the positive electrode active material layer, an amount of air space in a negative electrode active material layer, a swelling rate of the negative electrode active material layer, an amount of air space in a separator sheet, a total surface area of an opposing surface of the positive electrode active material layer and the negative electrode active material layer, and a reference electrolyte amount per unit surface area, which is determined in accordance with a binding rate.
