Summary:PROBLEM TO BE SOLVED: To provide a secondary battery pack capable of securing its safety even though an electrolyte is leaked out from a secondary battery. SOLUTION: The secondary battery pack 20 houses a battery pack 11, in which 7 sets of secondary batteries 4 are arranged like stacked straw bags of two steps of upper and lower sides and a series of spot welding is applied on a metal cap of the secondary battery, or a battery case bottom and metal connection plates 5, 6 served as one electrode, in an insulation case 12 formed by a deep insulation lower case 3 and a deep insulation upper case 2. Therefore, even though the electrolyte is leaked out from the secondary battery 4 forming the battery pack 11, leakage of the electrolyte to the outside can be prevented. COPYRIGHT: (C)2009,JPO&INPIT
