BATTERY
Document Type and Number:
Japanese Patent JP2023096745
Kind Code:
A
Abstract:
To provide a battery which can reduce contact failure.SOLUTION: A battery 100 comprises: a power generation element 10 having a positive electrode 1 to which a positive electrode terminal 4 is connected, a negative electrode 2 to which a negative electrode terminal 5 is connected, and a separator 3 sandwiched between the positive electrode 1 and the negative electrode 2; an insulator 20 which penetrates the power generation element 10 in a first direction z; and a first outer packaging 31 and a second outer packaging 32 which sandwich the power generation element 10 in the first direction z. A natural length of the insulator 20 in the first direction z is longer than a distance D between the first outer packaging 31 and the second outer packaging 32 in the first direction z. The insulator 20 has elastic force of 1 N or higher.SELECTED DRAWING: Figure 1
