Abstract: A battery charging method includes: charging a battery with a charging current; and changing the charging current in response to a current change event occurring during the charging of the battery, wherein the current change event occurs when the battery reaches a threshold voltage at which an anode potential of the battery reaches a reference value.

Abstract: A method of charging a lithium metal battery includes charging the lithium metal battery so that a constant voltage period and a first constant current period are separated from each other in time where, the lithium metal battery is charged so that a second constant current period occurs between the first constant current period and the constant voltage period, and a current value of the second constant current period is less than a current value of the first constant current period.
