Described is battery comprising a flexible pouch with two compartments wherein an electrochemical device is in the first compartment and the second compartment is empty. Channels for the conduction of gas connect the first and second compartments. When gases are formed during the initial charge and discharge cycles of the electrochemical device, the compartment containing the electrochemical device can be pressed on, driving the gas into the second, empty, compartment. The area between the two compartments can be sealed, and the second compartment cut off. This provides an easy, economical way of ridding an electrochemical device, such as a lithium-ion polymer cell of excess gases formed during the initial charge and discharge cycles.
