A team led by Argonne National Laboratory and including Brookhaven and Lawrence Berkeley National Laboratories and the University of Utah, is developing a new high energy redox couple (250 Wh/kg) based on a high-capacity full gradient concentration cathode (FCG) (230 mAh/g) ( earlier post ) and a Si-Sn composite anode (900 mAh/g).
Other silicon anode projects supported by the DOE includes those being done by Amprius, Angstrom Materials and NC State University. Consequently, the market may be poised for the entrance of a first wave of higher-energy density—and lower-cost—automotive Si-C cells in the 2014 or 2015 timeframe. Click to enlarge.
Tin (Sn) shows promise as a robust electrode material for rechargeable sodium-ion (Na-ion) batteries, according to a new study by a team from the University of Pittsburgh and Sandia National Laboratory. Rechargeable Na-ion batteries work on the same basic principle as Li-ion batteries—i.e., for the positive electrode.
