Described large capacity hangs down internal resistance ni-mh rectangular cell, it is characterized in that: each positive terminal assembly, the negative terminal assembly includes the pole bolt, the pole nut, insulating trip, a plurality of pole shoes and pole connecting plate, a plurality of pole piece spacings wherein, be fixedly installed on the bottom of pole connecting plate, adjacent pole shoe consists of groove, the upper end of baffle is inserted in the groove, the top of baffle is fixedly connected with the pole connecting plate, pole is bolted to the upper end of pole connecting plate, the upper end of pole bolt leans out housing, and and the interval is with insulating trip between the housing, and the pole nut is arranged on the pole bolt.
The utility model compared with prior art, its advantage is:
1) charging or discharging current of the low internal resistance ni-mh rectangular cell of large capacity is larger, and the electric current of positive and negative pole plate is drawn by the pole assembly.Because the utility model baffle is arranged on the long limit of every positive plate and every negative plate or the length of baffle is not less than half of every positive plate or every negative plate girth, can effectively reduce the average distance of baffle and plate active material each point, the conduction resistance of electric current descend and then so that under the large current condition resistance drop reduce, therefore when large current charge, positive/negative plate electric current turnover terminal voltage value at the whole story descends, can make gassing reduce current charges multiplying power and the life-span of having improved battery.
When 2) large capacity hanged down internal resistance ni-mh rectangular cell high current charge-discharge, the charge density that the surface that plate active material links to each other with electrolyte is born is maximum, and was lower than the deep layer active material utilization.Because the thickness of every positive plate is less than 0.4 millimeter, the thickness of every negative plate is less than 0.25 millimeter, reduced the thickness of active material conversion zone, surface area and overall conductance that plate active material links to each other with electrolyte have not only been improved, also improved the surface reactive material utilance, so the internal resistance of cell reduces further.
