Another nugget from the same article.....

By simplifying and standardizing the process used to convert silicon into nano-sized particles, the market potential of silicon anode batteries (and the products which could potentially utilize them) could be vastly expanded.

The latest lithium-ion batteries on the market are likely to extend the charge-to-charge life of phones and electric cars by as much as 40 percent. This leap forward, which comes after more than a decade of incremental improvements, is happening because developers have started working towards replacing the battery’s graphite anode with one made from silicon.
