3.1.4 Ni-Cd Battery
Nickel-cadmium (Ni-Cd) batteries have high power and energy density, high efficiency of charge/discharge, and a low cycle life (Table 2). The primary demerit of Ni-Cd batteries is a relatively high cost because the manufacturing process is expensive. In contrast, Cadmium is a toxic-heavy metal, hence posing issues associated with the disposal of Ni-Cd batteries. Ni-Cd batteries also suffer from “memory effect,” where the batteries only take a full charge after a series of full discharges [4].
