Batteries Ready to Turn the Corner

As the rest of the electronics industry has advanced by leaps and bounds, performance of the humble battery improves incrementally at best. Battery technology has remained relatively stagnant for more than a decade, while the impending explosion of the Internet of Everything (IoE) has increased the clamor for a more robust solution. This article reviews battery technology, looking at current champions like lithium-ion, along with flawed alternatives such as lithium-sulfur and lithium-silicon, as well as graphene-based designs and up-and-coming alternatives such as magnesium-ion. It discusses the benefits and drawbacks of each choice and tries to derive order out of the resulting chaos.
