20130196189 | NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, METHOD FOR MANUFACTURING NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, AND VEHICLE COMPRISING NONAQUEOUS ELECTROLYTE SECONDARY BATTERY - A nonaqueous electrolyte secondary battery includes a current interruption mechanism in at least one of a conductive pathway from the positive electrode sheet to the outside of the outer body and a conductive pathway from the negative electrode sheet to the outside of the outer body. The current interruption mechanism interrupts electric current when the pressure in the outer body exceeds a predetermined value. The nonaqueous electrolyte contains an overcharge inhibitor. The overcharge inhibitor is contained in an amount of 3.0% or more and 4.5% or less with respect to the spatial volume in the outer body in terms of volume ratio. The nonaqueous electrolyte secondary battery has excellent output characteristics in a low temperature condition and can sufficiently ensure reliability even when the battery is overcharged through two-step charging in a low temperature condition. | 08-01-2013 |
