Abstract
There is provided a risk-free and easy-to-use battery pack using battery cellsas a secondary battery, in which internal gases evaporated by applying overvoltage or the like thereto are processed inside a case to be prevented from leaking to the outside of the case and thereby even if the case has been led to rise in pressure due to a thermorunaway of the battery, the case is free from breaking. To realize this performance, the battery packis provided with a battery cell housingfor housing lithium cellsand a gas processorfor liquefying the internal gases g generated from the lithium cells
