Southern Federal University, Novoshakhtinsk branch, 2 Oktiabria Street, Town of Novoshakhtinsk, Rostov Region, Russia, 346900. In this research, there were obtained and analyzed experimental facts contradicting to the classical mechanism of the thermal runaway in nickel-cadmium batteries.
They provide back-up power for avionic and other critical on-board systems should the principal power source fail, and also start aircraft engines on the ground. Rail: Industrial nickel-cadmium batteries are widely used as back-up power in railways and underground metro systems.
The nickel-cadmium battery is one of the most reliable battery systems available today. It has thus become an obvious first choice for users looking for a reliable, long life, low maintenance system. It can be left in remote locations without the need for any maintenance.
They survive electrical abuse which would destroy a conventional battery, such as overcharging, deep discharging, and high ripple currents. Nickel-cadmium batteries have the ability to operate with limited performance loss in both low and high temperature environments, as well as in settings with large temperature swings.
Results: It has been established experimentally that a probability of a thermal runaway in the nickel-cadmium accumulators KSX-25 grows with an increase of a constant-voltage charge as well as of an environmental temperature and an accumulator time in service.
This enables preventive maintenance; a nickel-cadmium battery can be replaced before it no longer meets the requirements of the application. While the initial cost of a nickel-cadmium battery can be three to five times higher than an equivalent standard industrial battery, its Total Cost of Ownership is significantly lower.
