A common mode of failure of nickel-cadmium flooded pocket plate cells is iron poisoning of the positive plate due to transfer of iron into the active material from active materials and materials of construction. Nickel plated steel pockets are sometimes used to minimize iron dissolution, particularly on the positive electrode. Sometimesα-Fe2O3 is used as an additive to the …
Nickel Cadmium Fibre Electrode Batteries Nickel Cadmium Fibre electrode batteries may be seen as 3rd generation (1980''s) technology. Pocket plate is 1st generation (1919) and Sintered Plate is 2nd generation (1950''s). The Fibre Electrode Technology has been provided by DAUG, Germany (research venture of Mercedes Benz & Volkswagen).
In 1932 active materials were deposited inside a porous nickel-plated electrode and fifteen years later work began on a sealed nickel-cadmium battery. The first production in the United States began in 1946. Up to this point, the batteries were "pocket type," constructed of nickel-plated steel pockets containing nickel and cadmium active materials.
An original Nickel based battery still powers this 1912 electric car. Image: nickel-iron-battery Nickel based batteries were first invented over 100 years ago when the only alternative was lead acid and are so called because of their use of nickel metals in the electrodes (see Basic structure of a Nickel battery below). In the 20th century they …

The sintered-plate nickel-cadmium battery is a mature development of the nickel-cadmium system, having a higher energy density, up to 50% greater than its predecessor, the pocket-type construction. The sintered plate can be constructed in a much thinner form than the pocket plate, and the cell has a much lower internal resistance and gives ...
