New organic flow battery brings decomposing molecules back to life

After years of making progress on an organic aqueous flow battery, Harvard University researchers ran into a problem: the organic anthraquinone molecules that powered their ground-breaking battery were slowly decomposing ...

Here's why your internet may be delivered by a drone someday soon

As the pilotless flying wing came in for a landing, winds suddenly picked up. Facebook Inc.'s Aquila drone—powered by the sun and wider than a Boeing 737 jetliner—struggled to adjust. Just before landing, part of the ...

Startup aims to clean up the lithium-ion battery supply chain

Li-Cycle was little more than a drawing on the back of a napkin in a Yorkville coffee shop three years ago. Today, the startup founded by University of Toronto alumni is on the verge of an international expansion that its ...

Good news for rooftop solar, not for home batteries

The energy produced over the lifetime of typical rooftop solar panels more than makes up for the energy it takes to make, mount and then eventually recycle them. But adding a home battery usually lowers those dividends, according ...

New 'blue-green' solution for recycling world's batteries

Rice University researchers literally have a solution to deal with the glut of used lithium-ion batteries left behind by the ever-increasing demand for electric vehicles, cellphones and other electronic devices.

New approach could boost energy capacity of lithium batteries

Researchers around the globe have been on a quest for batteries that pack a punch but are smaller and lighter than today's versions, potentially enabling electric cars to travel further or portable electronics to run for ...

Team predicts the useful life of batteries with data and AI

If manufacturers of cell-phone batteries could tell which cells will last at least two years, then they could sell only those to phone makers and send the rest to makers of less demanding devices. New research shows how manufacturers ...

Battery (electricity)

In electronics, a battery or voltaic cell is a combination of many electrochemical Galvanic cells of identical type to store chemical energy and to deliver higher voltage or higher current than with single cells.

The battery cells create a voltage difference between the terminals of each cell and hence to its combination in battery. When an external electrical circuit is connected to the battery, then the battery drives electrons through the circuit and electrical work is done. Since the invention of the first Voltaic pile in 1800 by Alessandro Volta, the battery has become a common power source for many household and industrial applications, and is now a multi-billion dollar industry.
