Lithium & Lithium Ion Batteries: Explained In Simple Terms

By now anyone who uses cordless tools has heard at least something about lithium-ion batteries. In fact, they're currently one of the battery's most popular selling types, even with their added cost. So then what is it that makes this one particular type so different from the others?

One Type is Rechargeable and the Other is Not

The first thing you should know is that non lithium-ion and disposable lithium batteries are two completely separate types. Of course, one can be recharged, and the other can't, but their differences go much further than that. So to understand why this is so, you must know what an ion is. You can also look for the custom pack enclosures from NuEnergy Storage Solutions.

Lithium is in fact a metal

In simple terms, ions come in many forms, and they can best be described as free singular atoms that are free to engage in chemical reactions in solution. Lithium is actually a metal, and if you were to drop a chunk of it in water, it would just sit there.

Lithium Salts are Water Soluble

However; when lithium is paired up with another molecule, such as sulfur, it becomes lithium sulfide which is classified as salt. Now it's common knowledge that salts dissolve in water, so now if you drop a piece of lithium sulfide in water, it melts and the lithium atoms are freed up in the ionic form.

Do You Have a Clearer Picture Now?

So now you can perhaps get some idea how one type of battery that contains lithium in its non-ionic metal form can function so differently from Makita batteries that contain lithium in an ionic form. One has solid lithium metal in it, and the other has a salt of lithium in it.
