I expect better from Scientific American, yes technology these days stands on the shoulders of many smaller innovations, but it is the sum of all these small components and the software that makes a tech product innovative.
Also, the article refers to lithium-ion/lithium polymer batteries as lithium batteries. This is wrong, as lithium batteries are what you call primary cells with lithium anodes (e.g. button cells), not secondary cells like are used in a cellphone.
