Generating electricity from renewable sources will soon become as easy as putting a brush and a tube in a tub of wastewater. A carbon fiber, bottle-brush anode developed by Penn State researchers will ...

Cathode is the single most-expensive element, accounts for up to a third of a cell's cost The individual cells in most rechargeable EV batteries today have the same basic components: Electrodes, ...

This article will provide an overview on how to design a lithium-ion battery. It will look into the two major components of the battery: the cells and the electronics, and compare lithium-ion cell ...

Redox flow batteries that incorporate solid energy-storing materials are attractive for high-capacity grid-scale energy storage due to their high theoretical energy densities. However, their practical ...

Electric current comes in many forms: current in a wire, flow of ions between the plates of a battery and between plates during electrolysis, as arcs, sparks, and so on. However, here on Hackaday we ...
