Abstract
A gas suppression device for a lithium-sulfur battery includes a voltage measurement unit to measure a voltage of the lithium-sulfur battery; a current application unit to apply an electric current; and a control unit configured to control the current application unit to maintain the voltage of the lithium-sulfur battery within a predetermined range based on a voltage measurement result of the voltage measurement unit, to suppress gas generation in the lithium-sulfur battery having gone through an activation step.
Claims16
A gas suppression device for suppressing gas generation in a lithium-sulfur battery having gone through an activation step, comprising:
- a voltage measurement unit configured to measure a voltage of the lithium-sulfur battery;
- a current application unit configured to apply an electric current to the lithium-sulfur battery;
- and
- a control unit configured to control the current application unit to maintain the voltage of the lithium-sulfur battery within a predetermined range based on a voltage measurement result of the voltage measurement unit.
