NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY

A non-aqueous electrolyte secondary battery includes: an electrode group including a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode; a tape for securing at least a wound end of the electrode group; and a non-aqueous electrolyte. The negative electrode, at least in a charged state, includes a lithium metal and/or a lithium alloy. The tape has a tensile strength of 20 N/10 mm or less at an elongation ratio of 200% or more.
