From the article: "The tech supposedly makes the batteries up to ten times more efficient than their traditional counterparts, and even more importantly, the new tech is cheaper to produce."
Cheaper is meaningless in this context. For example, if the traditional counterparts cost $1,000/mile then $100/mile is still cheaper but still far from being pratical. We have no idea what it's cheaper than and by how much it's cheaper by.
Of course, my numbers are completely made. It's just meant as an example.
I'm pretty sure it is saying 10x better and cheaper than a standard lithium ion for the same battery size. If they are not saying that then the sentence makes no sense.
