Learn how electricity is made with rechargeable batteries

The secret ingredient in a lot of rechargeable batteries is a substance called Lithium carbonate.

Here in the States, Lithium carbonate is mined in a small town in Nevada by Western Lithium.

This documentary shows how Lithium carbonate is used to make rechargeable batteries:

Note: a commenter on YouTube disagreed with much of this documentary and said:

* Lithium is not rare. For example, it is 10,000 times more common that Uranium.

* Lithium-carbonate is not that expensive. It is actually pretty cheap. There is roughly $10 worth of lithium in a laptop computer, and well under $1 worth for a phone…

*Almost all battery cells can be recharged several times.

* Lithium batteries have a high electric potential. In fact, it is the highest of all fundamental elements. Only lead comes close. Besides high potential, it has a low physical mass. This combination makes lithium virtually unbeatable. Only hydrogen comes close, but it is hard to contain. Hydrogen batteries do exist and are fairly efficient.

* It is true about thinner layers increasing power. But at the same time, it decreases capacity.

* 150Wh/kg is not that impressive for a Lithium-carbon or cobalt based battery. Its actually a tradeoff for making them more powerful. Cellphone batteries have regularly over 200Wh/kg, and some high-spec laptop batteries draw almost 250Wh/kg.
