6 Frequently Asked Questions about “Mercury battery energy storage”

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.

How much mercury is in a battery?

The 1991 European Commission directive 91/157, when adopted by member states, prohibited the marketing of certain types of batteries containing more than 25 milligrams of mercury, or, in the case of alkaline batteries, more than 0.025% by weight of mercury. In 1998 the ban was extended to cells containing more than 0.005% by weight of mercury.

What are the advantages of a mercury battery?

Mercury batteries were very common in the 20th century and were used in many common small and large appliances. Advantages of the mercury battery include its long shelf life and steady voltage output. Mercury batteries use a mercury compound as the cathode with a zinc anode.

How many MW is a battery energy storage system?

It will have a total installed capacity of between 200-300MW. The BESS will connect to an existing 220 kV line via a new 33kV underground cabling into a new switching substation, and then into the Transpower substation, and onto the national grid. Why build a Battery Energy Storage System now?

What is the discharge curve of a mercury battery?

Mercury batteries using a mercury (II) oxide cathode have a very flat discharge curve, holding constant 1.35 V (open circuit) voltage until about the last 5% of their lifetime, when their voltage drops rapidly.

What mercuric oxide is used in a mercury battery?

Mercury batteries use either pure mercuric oxide or a mixture of mercuric oxide with manganese dioxide as the cathode. Mercury oxide cells are constructed with a zinc anode, a mercury oxide cathode, and potassium hydroxide or sodium hydroxide as the electrolyte. Since mercuric oxide is a non-conductor, some graphite is mixed with it.
