Abstract: A prismatic battery comprising a battery housing and a plurality of electrode plate cell groups, each said electrode plate cell group comprises a positive current collector and a negative current collector which are connected respectively to a positive electrode plate group and a negative electrode plate group, said battery housing comprises a plurality of cell compartments which are adapted for receiving said plurality of electrode plate cell groups, wherein, adjacent cell compartments being electrically connected by a pair of conductive bridging members which are disposed respectively in said adjacent cell compartments and said bridging members being connected electrically across said adjacent cell compartments by a plurality of electrical conductors which extend across said adjacent cell compartments, each said bridging member being electrically connected to a corresponding current collector at more than one locations.

Abstract: An electrical connector useful for both high-current and low-current applications including a first and a second conductive terminals, in which the terminals are interconnected by a plurality of substantially rigid and elongated conductive strips and apertures or gaps are disposed between at least some of the adjacent conductive strips. The connector provides enhanced heat dissipation characteristics and is particularly useful for high current applications such as for connecting batteries, accumulators, super-capacitors and the like storage power units for electric vehicle and other applications.

Abstract: A prismatic battery cell including a positive electrode group and a negative electrode group which are connected respectively to a positive current collector and a negative current collector, each said positive electrode group and said negative electrode group respectively including a plurality of positive and negative electrode plates, said positive and negative electrode groups are assembled so that positive and negative electrode plates are alternately stacked with separators interposed between adjacent positive and negative electrodes, wherein the electrode plates of an electrode group being bundled together and welded to the corresponding current collector, the welding being generally along the bundled portion of the electrode group and at least on the surface of said current collector away from said electrode group.
