    • An electrochemical cell (10) has a cathode current collector (20), an anode electrode (21) and a porous insulating material (22) wound in a coil (17) and inserted in a sealed can (11). Cathode current collector (20) has a metal substrate (23) carrying a plurality of holes (24). The metal substrate (23) supports layer (25) of an electrode material such as porous carbon. Both edges (26A, 26B) and one end (28) of the substrate (23) is kept free of material. The bare end (28) of the substrate (23) is on the outside of the coil (17). The substrate (23) is wider than the anode electrode (21) and the cathode current collector (20) of the coil (17), so that when the coil (17) is inserted in the can (11), the substrate (23) makes contact with all the internal surfaces of the can (11).
    • 电化学电池(10)具有卷绕在线圈(17)中并插入密封罐(11)中的阴极集电器(20),阳极电极(21)和多孔绝缘材料(22)。 阴极集电体(20)具有承载多个孔(24)的金属基板(23)。 金属基板(23)支撑多孔碳等电极材料的层(25)。 衬底(23)的两个边缘(26A,26B)和一个端部(28)保持没有材料。 基板(23)的裸露端(28)位于线圈(17)的外侧。 基板(23)比线圈(17)的阳极电极(21)和阴极集电体(20)宽,使得当线圈(17)插入罐(11)时,基板(23) )与罐(11)的所有内表面接触。
