Flow-through electrodes make hydrogen 50 times faster

Electrolysis, passing a current through water to break it into gaseous hydrogen and oxygen, could be a handy way to store excess energy from wind or solar power. The hydrogen can be stored and used as fuel later, when the ...

Self-healing liquid brings new life to battery alternative

Rechargeable lithium-ion (Li-ion) batteries are a revolutionary technology, found in everything from cellphones to cars. Their ubiquity and role in breaking dependence on fossil fuels earned a trio of researchers this year's ...

Tomorrow's coolants of choice

Later during this century, around 2060, a paradigm shift in global energy consumption is expected: we will spend more energy for cooling than for heating. Meanwhile, the increasing penetration of cooling applications into ...

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 ...
