Formation device and method for secondary battery

Abstract

According to embodiments of the present disclosure, a formation device for a secondary battery includes a temperature controller for controlling a temperature of the secondary battery, a temperature sensor for measuring the temperature of the secondary battery, a charging/discharging unit including a probe contacting a terminal of the secondary battery, a vacuum tube for removing gas inside the secondary battery, and a controller for charging the secondary battery until a state of charge of the secondary battery reaches a termination capacity, wherein the controller controls the temperature controller to maintain a set temperature range for the temperature of the secondary battery measured by the temperature sensor during the charging, and controls the vacuum tube during the charging, and wherein the termination capacity may be 40%-90%.
