A New Power Sources: Self-powered Wearable Tech

For emerging wearable tech to advance, it needs improved power sources. Now researchers have provided a potential solution via crumpled carbon nanotube forests, or CNT forests.

Potassium Metal Battery Emerges As a Rival to Lithium-ion Technology

Researchers demonstrate how they can overcome a persistent challenge known as dendrites to create a metal battery that performs nearly as well as a lithium-ion battery, but relies on potassium -- a much more abundant and less expensive element.
