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

Cycling performance of Li/SeS 2 ?C, 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. Unlike the widely studied Li/S system, both Se and Se x S y can be cycled to high voltages (up to 4.6

Researchers call for integration of materials sustainability into battery research; the need for in situ monitoring

Green Car Congress

In a review paper in the journal Nature Materials , Jean-Marie Tarascon (Professor at College de France and Director of RS2E, French Network on Electrochemical Energy Storage) and Clare Gray (Professor at the University of Cambridge), call for integrating the sustainability of battery materials into the R&D efforts to improve rechargeable batteries.

Electric Car Manufacturers Inspire New Paradigms -- Seeking Alpha

Tony Karrer Delicious EVdriven

The MiEV runs on a lithium-ion battery pack that can be charged in seven or so hours on a 240-volt line. The electric car features three different battery options, two different Lithium-based (LI) systems – A123Systems and Enerdel as well as a Sodium-Nickel battery Zebra (Mes-Dea). safety requirements.
