Abstract
Provided are a non-aqueous electrolyte secondary battery excellent in reliability and productivity, a method for manufacturing the same, and a system including the non-aqueous electrolyte secondary battery. A non-aqueous electrolyte secondary battery of the present invention includes a positive electrode, a negative electrode, a separator, and a non-aqueous electrolyte. The positive electrode includes a positive electrode mixture layer in which a lithium-containing composite oxide is used as a positive electrode active material. In a charged state, the negative electrode includes an aluminum foil or an aluminum alloy foil and a Li—Al alloy formed by reaction with Li ions deintercaleted from the positive electrode. The Li—Al alloy has a Li content of 7 to 29 atomic % with respect to 100 atomic % of a total of Li and Al at the end of charge.
