nickel-cadmium

The results of nickel cadmium accumulators (NCA) formation with the asymmetric and constant currents are represented. Accumulators formation with the asymmetric current allowed to reduce one-half the time of technological cycle of placing these accumulators in service, comparing with the constant current mode, with maintenance of their operational characteristics. Comparative characteristics of NCA operational parameters are given.

For nickel-cadmium batteries of stationary application, a global empiric correlation C(i) describing the dependency of released capacitance by the batteries at different discharge currents was suggested, which is true for batteries of any capacitance and any mode of discharge (H, M, L). The global correlation C(i) can be described by generalized Peukert's equation, Korovin-Skundin's equation, probability integral, and porous electrode equation with accuracy sufficient for practical application.
