Abstract
A nonaqueous electrolyte battery has a positive electrode, a negative electrode and separator laminate rolled into a spiral electrode unit contained in an external case filled with nonaqueous electrolyte. Battery voltage is between 3.5 V and 5.0 V when charged. A positive electrode supporting member material and the external case are both aluminum. The positive Electrode supporting member is exposed for at least a portion of the outermost winding of the spiral electrode unit, and this exposed supporting member contacts the inner surface of the external case to make an electrical connection.
