Ecological power storage battery made of vanillin

Researchers at TU Graz have found a way to convert the aromatic substance vanillin into a redox-active electrolyte material for liquid batteries. The technology is an important step toward ecologically sustainable energy ...

Lithium batteries charge faster thanks to nanochannels

New technology to be used in lithium batteries can make them charge faster. The material graphite that was often used, already had a successor that could not further be improved, was the assumption. Until now, as researchers ...

Researchers create better material for wearable biosensors

Biosensors that are wearable on human skin or safely used inside the body are increasingly prevalent for both medical applications and everyday health monitoring. Finding the right materials to bind the sensors together and ...

Materials in lithium-ion batteries may be recycled for reuse

China expects to generate 2.5 billion end-of-life lithium-ion batteries from portable electronics such as smartphones and laptops in 2020, but very few are recycled. Although these batteries are discarded, the metals inside ...

Thin layer protects battery, allows cold charging

In the search for a reliable, quick-charging, cold-weather battery for automobiles, a self-assembling, thin layer of electrochemically active molecules may be the solution, according to a team or researchers.

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.
