A billion holes can make a battery

Researchers at the University of Maryland have invented a single tiny structure that includes all the components of a battery that they say could bring about the ultimate miniaturization of energy storage components.

Efficiency of water electrolysis doubled

Researchers have boosted the efficiency of water electrolysis. They applied a layer of copper atoms in a conventional platinum electrode. Thus, reaction intermediates could desorb a bit more easily from the catalyst surface. ...

Kitchen sponge supercapacitor has many porous benefits

By dipping small pieces of an ordinary kitchen sponge into solutions of nanoscale electrode materials, scientists have created a light-weight, low-cost supercapacitor that benefits from the sponge's porous structure. The ...

Engineers develop floating solar fuels rig for seawater electrolysis

In a single hour, more energy from the sun hits the Earth than all the energy used by humankind in an entire year. Imagine if the sun's energy could be harnessed to power energy needs on Earth, and done in a way that is economical, ...

New manufacturing approach slices lithium-ion battery cost in half

An advanced manufacturing approach for lithium-ion batteries, developed by researchers at MIT and at a spinoff company called 24M, promises to significantly slash the cost of the most widely used type of rechargeable batteries ...

Electrode

An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte or a vacuum). The word was coined by the scientist Michael Faraday from the Greek words elektron (meaning amber, from which the word electricity is derived) and hodos, a way.
