Everything You Need to Know the Minerals in Batteries

Battery, Batteries, Rechargeable, Energy, ElectricityBatteries are powered by a variety of minerals from all over the world. This is an exploration of which minerals are used, how these minerals work, and how the battery industry is faring today.

Which Minerals Are Used in Batteries?

When you build a battery, there are four overarching components that you need to fill. These are the internal hardware, the electrolyte, the chemistry, and the casing. The core of these components is made of up foundation blocks; foundation blocks are the raw versions of materials that are needed to construct a battery.

There are numerous materials and minerals involved in the physical construction of a battery. However, the most important mineral is the battery’s chemical. This might be several different types of mineral:

  • Nickel
  • Lithium
  • Lead
  • Cobalt
  • Cadmium
  • Other rare earth minerals

Why is the chemical component of a battery so important? Batteries, broken down to their most basic form, are systems that are designed to convert and store electrochemical energy. This electrochemical energy is then used to provide portable power sources to an appliance or other device. If chemistry didn’t change the stored chemical energy into electric energy, the batteries wouldn’t be able to power anything. This is why it’s crucially important for the minerals used in batteries to be available.

The price of a battery tends to be dictated by the supply of the necessary raw material that is available. If raw materials are in short supply, the cost of the battery will be higher than it would be if there was an abundance of raw material. In the United States, 6,841 mining operations are unearthing everything from zircon to aluminum. Though this sounds like a large number of mining operations, that number must then be evaluated against the total mineral demand. Every American who was born in 2007 is expected to use these amounts of mineral commodities over the span of their life:

  • 5,677 pounds of aluminum
  • 65,480 pounds of cement
  • 19,245 pounds of clay
  • 1,309 pounds of copper
  • 1,576 ounces of gold
  • 29,608 pounds of iron ore
  • 928 pounds of lead
  • 19,815 pounds of phosphate rock
  • 1.61 million pounds of gravel, sand, and stone
  • 671 pounds of zinc

In 2007, 4,315,000 babies were born in the United States. That’s more than four million people using up this massive amount of minerals. When compared to the numbers, 6,481 mines isn’t nearly enough to cover the massive demand for minerals.

Minerals Broken Down By Numbers

Currently, Chile is the leading producer of lithium chemicals. The following most major producers of the chemical are China, Argentina, and the United States. The United States is the lead consumer of lithium-related minerals and compounds. In addition, the US is the foremost producer of lithium materials with value added. Only one company in the US produced any lithium compounds — Silver Peak Mine, run by the Chemetall Foote Corporation in Nevada.

Not only is lithium used in batteries, but it’s used in glass, ceramics, lubricating grease, polymers, pharmaceuticals, aluminum production, air conditioning, chemical processing, continuous casting, and treatment of bipolar disorder. The USGS estimates that the United States used 5,000,000 pounds of chemical lithium in its batteries in 2005.

Meanwhile, cadmium was estimated to have seen 1,312,000 pounds of use in rechargeable batteries over the same time period.

Cobalt, which is primarily used for the electrodes of a battery, has a usage total of a staggering 23,800,000 pounds in rechargeable batteries.

Regarding the annual quantity of overall nickel consumption, the estimate by the USGS places nickel usage at 426,000,000 pounds of nickel used in rechargeable batteries.

What’s the Demand?

An estimated 350 million batteries are purchased in the United States each year. This means that billions of batteries have been bought and are currently in circulation. Such demand will ensure that mining operations continue for a long time. Right now, enough metals and minerals are available for extraction from mines. But decades down the road, the mineral industry could face serious problems.
