1. A battery comprising:

  • a battery cell including an electrode a second potential electrode in electrical contact with a sheet shaped second potential electrode current collector and an electrolyte in contact with the electrode and the second potential electrode; and

    an extended portion of the second potential electrode current collector extending beyond the second potential electrode for dissipating heat from inside the battery to the atmosphere,wherein the electrode is a laminate including electrode material in electrical contact with a sheet shaped electrode current collector and wherein the second potential electrode is in electrical contact with the second potential electrode current collector on two sides of the second potential electrode current collector, the laminate is folded around the second potential electrode and the second potential electrode current collector such that the electrolyte is in contact with the second potential electrode on two sides of the second potential electrode current collector, the extended portion of the second potential electrode current collector extending from between the folded laminate.
