| 摘要 |
<p>The invention relates to electrical technology and can be used in the production of alkali accumulators based on various electrochemical systems. The proposed alkali accumulator has positive and negative electrodes (1 and 2 respectively) separated by a multi-layer separator consisting of layers (3, 4), and a porous metal foil (5) situated between the electrodes (1, 2), these elements being enclosed in a housing containing electrolyte. The foil (5) is arranged between the layers (3, 4) of the separator and may be contiguous with one of the electrodes (1, 2). The porous foil (5) is 50 to 200 νm thick, has a porosity of 30 to 60 % and a pore size of 1 to 20 νm. The porous foil (5) may be of nickel. The alkali accumulator has improved reliability and more stable discharge characteristics.</p> |
