Non-aqueous electrolyte secondary battery with filling function, and non-aqueous electrolyte secondary battery and non-aqueous electrolyte filling device used therefor

摘要

A secondary battery with filling function has a corresponding secondary battery and a filling device. The corresponding secondary battery has a housing defining an accommodation chamber for accommodating a power generation portion, an opening portion formed in the housing, a stopper body closing the opening portion, and a coupling portion formed around the opening portion. The filling device has a cap body forming a sealed space around the opening portion by covering the opening portion and the stopper body closing the opening portion as a result of coupling to the coupling portion, an attachment and removal portion for attaching and removing the stopper body to/from the opening portion in the sealed space, and a filling portion for filling the inside of the housing with a non-aqueous electrolyte through the opened opening portion.
