The battery packs are used in items such as cordless telephones, cordless power tools, hand-held vacuums and video cameras. These batteries are rechargeable and are found in traditional cylindrical battery sizes as well as in a wide variety of battery packs. Nickel cadmium batteries consist of a nickel cathode, a cadmium anode, and an alkaline solution for an electrolyte. Rechargeable Battery Types Nickel Cadmium Batteries Please note that AERC charges fees to recycle these battery types.Īlkaline and zinc carbon battery types no longer contain mercury and they may be disposed in your normal household trash. AERC Recycling Solutions in Allentown (1-86) does recycle these battery types. There are limited options for recycling alkaline and zinc carbon batteries. Today, alkaline batteries on the market are required to have zero-added mercury and are no longer hazardous.
Recent laws have restricted the levels of mercury allowed in alkaline and zinc-carbon batteries. In the past, mercury was added to these batteries to prevent corrosion and the creation of hydrogen gas. The electrolyte in an alkaline battery is usually potassium hydroxide or sodium hydroxide, while in a zinc carbon battery the electrolyte is ammonium chloride or zinc chloride. Non-Rechargeable Battery Types Alkaline and Zinc Carbon BatteriesĪlkaline and Zinc Carbon Batteries typically contain a manganese dioxide cathode and a zinc anode. The following summary provides general information on the recycling options for household batteries. Various metals are used in the cathodes and anodes. The anode is a positive terminal, the cathode is the negative terminal, and the electrolyte is the chemical solution through which the electrons flow from the anode to the cathode, creating an electrical charge. Household batteries, commonly known as dry cell batteries, are comprised of an anode, a cathode, and an electrolyte.
