6) Zinc-air cells (primary batteries)
7) Lead-acid cells (rechargeable batteries)
8) Nickel-cadmium cells (rechargeable batteries)
These batteries are characterized by high energy density in proportion to mass, long life, a large amount of charge and discharge cycles and a very low self discharge ratio. The cathode is made from nickel (Ni(OH)₂)and the anode from cadmium . The electrolyte is potassium hydroxide (KOH). The biggest advantage of this type of battery is the possibility of fast charging. They are harmful to the environment because of the effete cadmium.
