Battery and electric apparatus having same

A battery, comprising a housing and a battery cell accommodated in the housing, wherein the housing comprises a first housing body and a second housing body fitting with the first housing body, the battery cell comprises a first electrode plate and a second electrode plate, and the first electrode plate and the second electrode plate are wound around a conductive structure provided in a hollow cell winding space to form the battery cell;

• wherein the conductive structure comprises a first conductive part and a second conductive part electrically isolated from each other;
• and
• the first conductive part is connected with the first electrode plate and in electrical communication with the first housing body, the second conductive part is connected with the second electrode plate and in electrical communication with the second housing body, and the first housing body and the second housing body are electrically isolated from each other;
• wherein the first electrode plate comprises a first current collector and a first active material layer disposed on the first current collector;
• and in a longitudinal direction of the first electrode plate, the first current collector comprises a first portion and a second portion directly connected with the first portion, wherein the first portion is a blank region uncoated with the first active material layer, and the first portion is located at an inner ring of the battery cell and connected with the first conductive part, and in a width direction of the first current collector, a width of the first portion is less than a width of the second portion.
