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, ...

Scientists design organic cathode for high performance batteries

Researchers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have designed a new, organic cathode material for lithium batteries. With sulfur at its core, the material is more energy-dense, cost-effective, ...
