Rechargeable battery

摘要

A rechargeable battery, including a first electrode including a first metal plate, a first coated region where a first material is applied onto the first metal plate, and a first uncoated region, the first metal plate having a first thickness in the first uncoated region and a second thickness in the first coated region, the first thickness being greater than the second thickness, a second electrode including a second metal plate, a second coated region where a second material is applied onto the second metal plate, and a second uncoated region, a separator between the first electrode and the second electrode, a case housing the first electrode, the separator, and the second electrode, and a current collecting plate connected to the first uncoated region through a side thereof.

主权项

1. A rechargeable battery, comprising:
at least three first electrodes, each of the first electrodes including a first metal plate, a first coated region where a first material is applied onto the first metal plates, and a first uncoated region, the first metal plates having a first thickness in the first uncoated regions and a second thickness in the first coated regions, the first thickness being greater than the second thickness, the first uncoated regions being formed by folding a part of all of the first metal plates at an outer end of the first uncoated region of each of the first metal plates, the folded part overlying an unfolded part in an overlapping face to face relationship; a second electrode including a second metal plate, a second coated region where a second material is applied onto the second metal plate, and a second uncoated region; a separator between the first electrodes and the second electrode; a case housing the first electrodes, the separator, and the second electrode; and a current collecting plate connected to the first uncoated regions through a side thereof.
