1,015,914. Electric storage cells. SOC. DES ACCUMULATEURS FIXES ET DE TRACTION. July 4, 1962 [July 5, 1961; June 5, 1962], No. 25715/62. Heading H1B. A sealed storage cell (specifically Ni/Cd) is assembled with the electrodes spaced from 0À1-0À3 mm. apart and the cell is sealed with the partial pressure of oxygen in the cell greater than that in the atmosphere at the same pressure. This avoids increased pressure in the cell because of hydrogen build up when charging. |
