3) Silver oxide cells (primary batteries)
4) Mercury cells (primary batteries)
5) Lithium cells (primary batteries)
6) Zinc-air cells (primary batteries)
Most often used in hearing aids, pagers and telemetrical appliances. The cathode is oxygen (O₂) and the anode pulverized zinc. The electrolyte is potassium hydroxide (KOH). These batteries use a catalytic reaction of zinc oxidation with the oxygen taken from the air. Thanks to eliminating the traditional cathode the energy density per mass unit is very high in zinc-air cells. An additional advantage is a very long storage period (up to 4 years in factory packaging).The battery will work for about 2-4 months after unpacking.

9) Nickel-metal hydride cells (rechargeable cells)
