New high energy, highly stable cathode for sodium-ion batteries

Green Car Congress

F 0.7 , for sodium-ion (Na-ion) batteries (NIBs). While high-energy Li-ion batteries (LIBs) are expected to contribute in part to the solution, the high cost and low stability prohibit wide application in this area, the researchers observe. In a prior study, they developed a new Li-ion battery electrode—Li 1.1

U Waterloo team identifies key reaction in sodium-air batteries; implications for improving Li-air

Green Car Congress

Chemists at the University of Waterloo have identified the key reaction that takes place in sodium-air batteries. Understanding how sodium-oxygen batteries work has implications for developing the more powerful lithium-oxygen battery, which has been proposed by some as the “holy grail” of electrochemical energy storage.

ANL team develops new class of Li- and Na- rechargeable batteries based on selenium and selenium-sulfur; greater volumetric energy densities than sulfur-based batteries

Green Car Congress

Researchers at Argonne National Laboratory have developed selenium and selenium–sulfur (Se x S y )-based cathode materials for a new class of room-temperature lithium and sodium batteries. A paper on their work is published in the Journal of the American Chemical Society. V) without failure. However, both Li/S and Li/O 2. S y systems.

European automotive and automotive battery industries call for extension of the exemption of lead-based batteries from the EU ELV Directive

Green Car Congress

The EU must continue to allow the use of lead-based batteries in vehicles as they are essential for the needs of future generations of European cars, according to the automotive and automotive battery industries in Europe. This electrical system is in all cases supplied by a 12V lead-based battery, the groups said.
