Batteries for nuclear power plants in EuropeDr Mike
In the time from the Second World War to the 60es open Plantè cells were used for the utilities. The open Plantè cells consisted out of glass containers without lid, the positive plate was Plantè, the negative also Plantè or a box plate both antimony-free. The connectors were made out of lead. The cells could be repaired, if bulging of plates or short circuits occurred. So the lifetime was in the range of 20 to 25 years. But because of the open cell design new developments in the 60es removed the open Plantè.
