Engineers reveal cause of key sodium-ion battery flaw

Scientists have discovered the source of a problem limiting the durability of sodium-ion batteries. Scientists provided manufacturers with new strategies for powering the 21st century. Sodium-ion batteries are a promising technology for electric vehicles. As they are made from abundant materials that are energy...

New fuel cells can operate at temperatures between -20 to 200°C

Proton exchange membrane fuel cells are power cells. It can transform the chemical energy produced in the time of electrochemical reaction between hydrogen and oxygen into electrical energy. These cells are highly promising energy solutions. They operate at limited temperature ranges like 80 to...

Scientists explore the reason why some attempts to convert the greenhouse gas into fuel fails

Scientists have tried to chemically convert carbon dioxide into fuels. But these processes did not work out well in real life. Scientists from MIT have identified the major reason for poor performance in such conversion systems. The reason is a local depletion of the carbon...

‘Ocean battery’ targets renewable energy quandary

A wind turbine sitting idle on a calm day and spinning swiftly when power demand has a problem for renewables. Scientists think this problem can be sorted under the sea. Offshore wind farms can use seawater to essentially store energy. This helps us in fossil...
