Abstract: A nickel hydrogen secondary battery 2 has an outer can 10, and an electrode group 22 accommodated together with an alkali electrolyte solution in the outer can 10. The electrode group 22 includes a positive electrode 24 and a negative electrode 26 stacked through a separator 28. The positive electrode 24 includes a first positive electrode active substance and a second positive electrode active substance. These first and second positive electrode active substances each contain nickel hydroxide as a main component, and the first positive electrode active substance and the second positive electrode active substance differ in the amount of magnesium solid-dissolved.

Abstract: A battery cell includes an electrode, a terminal, and a current-interrupt device configured to electrically isolate the terminal from the electrode. The current-interrupt device includes a plate connected to the electrode and defining a hole, and a diaphragm connected to the terminal and joined to the plate forming a ceiling of the hole. A cover of the current-interrupt device is joined to the plate forming a floor of the hole. A dielectric fluid is disposed in the hole. The diaphragm and cover are configured to move toward the terminal, in response to pressure within the cell exceeding a threshold, to separate the diaphragm from the plate forming a gap therebetween and to release the fluid into the gap preventing current from arching across the gap.

The insulating layer is formed of a resin composition containing a modified polyolefin resin modified with an unsaturated carboxylic acid or acid anhydride thereof and has a hardness, when measured by using a nanoindenter and pressing an indenter 5 μm into the insulating layer from a cross-section of the laminate in the laminating direction thereof, that ranges from 10 MPa to 300 MPa. In the sealant layer, an elastic modulus, when measured by using a nanoindenter and pressing an indenter 5 μm into the sealant layer from a cross-section of the laminate in the laminating direction thereof, ranges from 100 MPa to 1000 MPa.

Abstract: Techniques for monitoring an internal pressure of a battery cell, whereby a membrane that is part of an outer shell of the battery cell is used as an element of capacitive-based or inductive-based sensor circuitry in order to measure a change of capacitance or inductance under deformation of the membrane from the internal pressure of the battery cell. The change of capacitance or inductance may in turn be used to derive a value for the internal pressure of the battery cell.
