PURPOSE:To improve hermetically sealed reaction efficiency, discharging capacity and deep discharging cycle lifetime by composing a group of plates with positive plates, negative plates and specific separators, employing specific dilute sulfuric acid and providing spaces in the partial side areas of the group of plates. CONSTITUTION:A group of plates is composed of positive plates 1, negative plates 2 and separators 3 made of flexible flat perforated plates mainly including glass fibers with average diameter of 5-25 micron and installed in a battery jar 6 provided with a valve 7. Respective spaces 8 are formed between each of the separators 3 on both sides and each inner wall of the battery jar 6 to serve as a passage for fuel oxygen. Gelatinous dilute sulfuric acid electrolyte 9 including 3-7 percentage by weight of silica grain is provided in the holes of the separator 3 and partial areas of the spaces 8. Therefore, the quantity of the electrolyte staying in the separator becomes large to put the space reaction efficiency to be enhanced and also sulfuric acid diffuses from soft gelatinous electrolyte to prevent the liquid in the group of plates from being neutralized. And also, generation of difference of density between upper and lower parts of electrolyte by repeat of deep discharging can be prevented by the difference in steam pressure to improve hermetically sealed reaction efficiency, discharging capacity and deep discharging cycle lifetime. |
