摘要:
A non-aqueous electrolyte secondary battery comprising: a case comprising a bottom and a sidewall; a rolled body comprising: a positive electrode comprising a first electric plate and a positive electrode active material applied on the first electric plate; a negative electrode comprising a second electric plate and a negative electrode active material applied on the second electric plate; and a separator inserted between the positive electrode and the negative electrode; wherein the rolled body is formed by laminating and rolling the positive electrode, the negative electrode, and the separator; and wherein the rolled body is enclosed in the body; non-aqueous electrolyte enclosed in the case; a header used for sealing the case; a plurality of positive electrode leads connecting the positive electrode and the header; a plurality of negative electrode leads connecting the negative electrode and a bottom of the case; and holding means for holding the rolled body so that the rolled body does not relatively move with respect to the case while keeping a gap between a lower terminal of the rolled body and the bottom of the case and a gap between an upper terminal of the rolled body and the header.
