| abstract |
A battery subjected to a charging/discharging including at least initial charging is configured such that a power generating element constituting a laminated positive electrode and negative electrode separated by a separator is stored within a covering along with a nonaqueous electrolyte and an additive, the covering is sealed with a terminal leading out of the covering, and a relational expression R E < R C < R A is defined by using a total amount of presence W E of the additive component in the electrolyte, W C of the additive component in the positive electrode, and W A of the additive component in the negative electrode after charging/discharging as W T , and by using an abundance ratio of W E with respect to the total amount of W T , W C with respect to the total amount of W T , and W A with respect to the total amount of W T as R E , R C , and R A . |
