Chalmers team develops graphite-like anode for Na-ion batteries; Janus graphene

Green Car Congress

Researchers at Chalmers University of Technology, Sweden, have developed a nanometric graphite-like anode for sodium ion (Na + storage), formed by stacked graphene sheets functionalized only on one side, termed Janus graphene. The estimated sodium storage up to C 6.9 Na is comparable to graphite for standard lithium ion batteries.

Chinese steel group Tsingshan investing $375M to build lithium plant in Argentina with Eramet

Green Car Congress

The project consists in extracting brine from the salar and processing it into lithium carbonate. Fresh water is then used to release the stored lithium. Purification of the lithium, then reaction with sodium carbonate to convert it to lithium carbonate.

Researchers develop rechargeable hybrid-seawater fuel cell; highly energy density, stable cycling

Green Car Congress

The circulating seawater in the open-cathode system results in a continuous supply of sodium ions, endowing the system with superior cycling stability that allows the application of various alternative anodes to sodium metal by compensating for irreversible charge losses. an alloying material), in full sodium-ion configuration.

Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. The present sodium-sulfur battery operates above 300 °C. A = lithium or sodium (Li or Na), M represents a metal and 1 ≤ n < z. —Lu et al.

Drexel researchers demonstrate intercalation of MXenes with a variety of ions; high volumetric capacitance

Green Car Congress

A variety of cations, including Na + , K + , NH 4 + , Mg 2 + , and Al 3 + , can also be intercalated electrochemically, offering capacitance in excess of 300 farads per cubic centimeter (much higher than that of porous carbons). This capacity is significantly higher than what is currently possible with porous carbon electrodes.

Researchers demonstrate concept desalination battery

Green Car Congress

A team from Stanford University and Ruhr-Universität Bochum have demonstrated the novel concept of a “desalination battery” that uses an electrical energy input to extract sodium and chloride ions from seawater and to generate fresh water. Wh l –1 ), the most efficient technique presently available. Click to enlarge.

UW researchers discover major lithium resource in Wyoming; potential integrated brine production/CO2 storage system

Green Car Congress

Researchers at the University of Wyoming Carbon Management Institute (CMI) discovered a major new lithium resource near Rock Springs during a geological carbon dioxide storage site characterization project sponsored by the US Department of Energy. Presently, the US imports more than 80% of the lithium used domestically.
