Abstract
A method for manufacturing an electrochemical device includes a discharge pretreatment step, where, external electric power is applied to a battery to discharge the battery, before charging the battery for the first time to perform formation of the battery, in order to remove a byproduct layer on the surface of a negative electrode. The method including the discharge pretreatment step before the first charge of a battery can improve the cycle life of an electrochemical device.
