Industrial Ni-Cd batteries are rugged, long-life, cheap batteries capable of operating at high rates. The so-called pocket-plate battery can stand overcharge, polarity reversal and short-circuits. To better utilize the electrode materials, two other structures have been developed: the fiber plate and the plastic-bonded plate. The latter has afforded improved performance characteristics (e.g. an energy density of 110 Wh/1).
The negative electrode is Cd, the positive NiOOH, and the electrolyte is a concentrated solution of KOH (with additions of LiOH). The overall reaction is:
The discharge voltage is about 1.2 V. Under normal conditions, an industrial battery can reach 2,000 cycles and lifetimes of 8-25 years. This battery can practically be used in all industrial applications, with capacities ranging from 10 to 1,000 Ah.
A recent development of the Ni-Cd system is the sintered-plate battery having an energy density higher (up to 50%) than that of the pocket-plate one. It is used in highpower applications,e.g. in turbine engines and many military uses.
