A team at the University of Maryland have synthesized a mixed conducting nanocomposite sulfur electrode that consists of different nanoparticles with distinct properties of lithium storage capability, mechanical reinforcement, and ionic and electronic conductivities. The poor performance of these ASSLSBs was related to two main challenges.

Argonne National Laboratory seeks to disrupt the steel industry by developing a potentially zero-carbon ironmaking process that eliminates the use of coke or natural gas and requires less energy than current processes. This would eliminate the ionomer, which conducts ions, but also poisons catalyst sites and obstructs oxygen transport.

In response to the Funding Opportunity Announcement issued by AFOSR on 3 April 2009, the Princeton-led team proposed a solution based on the use of graphene—molecular sheets of carbon atoms. Graphene is a one-atom thick planar sheet of carbon in a honeycomb lattice. The resulting flakes are 200- to 500-nanometers wide.

This includes research on appropriate anodes, cathodes, and electrolytes for magnesium (Mg)-, sodium (Na)-, and lithium (Li)-based batteries and novel transition metal oxide- and nitride-based supercapacitor electrode materials. Magnesium is much more abundant in the Earth’s crust, making it less expensive than Li by a factor of 24.

Rechargeable magnesium batteries are of great interest as potential “beyond Li-ion” systems for extended electric vehicle range. Because magnesium is divalent, it can displace double the charge per ion (i.e., Mg 2+ rather than Li + ). As an element, magnesium is more abundant than lithium, and more stable. Earlier post.)
