Hazardous ingredients in batteries

Mercury battery

A mercury battery (also called mercuric oxide battery, mercury cell, button cell, or Ruben-Mallory [1]) is a non-rechargeable electrochemical battery, a primary cell. Mercury batteries use a reaction between mercuric oxide and zinc electrodes in an alkaline electrolyte. The voltage during discharge remains practically constant at 1.35 volts

Hazardous ingredients in batteries

Both in Switzerland and in the EU, the trade and sale of batteries containing mercury (chemical: Hg) or cadmium (Cd) are severely restricted. There is a limit value for mercury in batteries of 5 mg/kg and of 20 mg/kg for cadmium. For a lead content of more than 40 mg/kg, a corresponding declaration on the battery or on the packaging is mandatory.

6 FAQs about [Is there mercury in lead-acid batteries Why ]

Which batteries contain mercury?

Today the only types of batteries in the United States that contain mercury are button cell batteries and mercuric oxide batteries. The Mercury-Containing and Rechargeable Battery Management Act of 1996 prohibits the use of mercury in all other types of batteries.

Are mercury batteries bad for the environment?

Mercury became a popular component of batteries in the 1940s due to its highly stable voltage. Mercury batteries also had a greater capacity than others at the time, which was another reason for their success. But in recent times, the negative impact of mercury on the environment has been realized, particularly when it is not disposed of correctly.

Why do button cell batteries contain mercury?

Build-up of hydrogen gas can cause the battery to leak, limiting the ability of the battery to function. Mercury suppresses this zinc corrosion, which is why it is added to button-cell batteries. These batteries may contain mercury in the insulating paper surrounding the battery, or mercury may be mixed in the anode itself.

How to prevent mercury from entering the environment from batteries?

The most effective and also the most economical way to prevent mercury from entering the environment from batteries is to phase out the use of mercury in batteries to the fullest extent possible, an effort already instituted by the battery manufacturers, and to maintain an effective collection system for the mercury batteries still in use. Y P 5.

What is a mercury battery used for?

Mercury batteries were used in the shape of button cells for watches, hearing aids, cameras and calculators, and in larger forms for other applications. For a time during and after World War II, batteries made with mercury became a popular power source for portable electronic devices.

Can battery recycling reduce mercury?

The battery industry has made a concerted and relatively successful effort during the past decade to eliminate mercury from their products, and, in combination with mercury recycling, these efforts may be expected to significantly reduce the addition of mercury from batteries to communal waste streams.
