Expanding the temperature range of lithium-ion batteries

Electric cars struggle with extreme temperatures, mainly because of impacts on the electrolyte solutions in their lithium-ion batteries. Now, researchers have developed new electrolytes containing multiple additives that ...

Toward a low-cost industrialization of lithium-ion capacitors

Combining two additives instead of one to facilitate the incorporation of lithium within capacitors: that is the solution proposed by researchers from l'Institut des matériaux Jean Rouxel (CNRS/Université de Nantes), in ...

An affordable way to store clean energy

Renewable energy sources can fluctuate in the amount of power they are able to provide—which is why batteries are used to temporarily store the energy. The problem with lithium ion batteries is their short service life, ...

The most complete study of battery failure sees the light

An international team of researchers just published in Advanced Energy Materials the widest study on what happens during battery failure, focusing on the different parts of a battery at the same time. The role of the ESRF, ...

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.
