DeWalt just sent us an interesting analogy explaining their new Nano technology by comparing it to a bucket filled with balls: 

There are many types of lithium ion batteries- you can add many different combinations of chemical formulas. We specifically use phosphate in ours. Nano is a measurement of size. It is very small- there are 25 million nano-meters in an inch. Nano sized particles gives you energy density. Imagine two identical 5 gallon buckets. In the first bucket, you fill it with softballs. In the second bucket, you fill it with marbles. The bucket with marbles will be more densely packed (less air around the marbles due to the smaller size). Nano is like the marble example.

So essentially, DeWalt's Nano batteries allow more energy to be stored in the same amount of space. Interesting!
