BATTERY WITH MANDREL FOR WINDING ELECTRODES

摘要

A battery (100) includes a mandrel, a positive (34) electrode, a negative (32) electrode, and a separator (30) provided between the positive electrode and the negative electrode. The positive electrode, the negative electrode, and the separator are wound around the mandrel (20), and the mandrel includes an extension (24) configured to be coupled to a mechanism (25) for winding at least one of the positive electrode, the negative electrode, and the separator around the mandrel.
