Non-Aqueous Rechargeable Battery and Method for Manufacturing Non-Aqueous Rechargeable Battery
A non-aqueous rechargeable battery includes an electrode body, a non-aqueous electrolyte solution, and a case. In the electrode body, a cathode sheet and an anode sheet are stacked with a separator arranged in between. The case accommodates the electrode body and the non-aqueous electrolyte solution. A cell compression parameter obtained by dividing a cell compression force, obtained by multiplying a difference of an internal pressure of the case relative to an atmospheric pressure by an area of a flat portion of the electrode body, by a spring constant of the case is in a range of 0.000 to 0.007.
1 . A non-aqueous rechargeable battery, comprising:
an electrode body in which a cathode sheet and an anode sheet are stacked with a separator arranged in between;
a non-aqueous electrolyte solution; and
a case accommodating the electrode body and the non-aqueous electrolyte solution,
wherein a cell compression parameter obtained by dividing a cell compression force, obtained by multiplying a difference of an internal pressure of the case relative to an atmospheric pressure by an area of a flat portion of the electrode body, by a spring constant of the case is in a range of 0.000 to 0.007.
