Faradion demonstrates proof-of-concept sodium-ion electric bike

Green Car Congress

For the proof-of-concept, the cells were manufactured to be larger than necessary to avoid unnecessary costs and lengthy manufacturing processes at this early stage. Sodium-ion intercalation batteries—i.e., Thus, insertion/deinsertion of sodium ions in a host material is much more difficult than that of lithium ions.

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.

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.

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.

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. The present sodium-sulfur battery operates above 300 °C. A typical Li-air battery discharges at 2.5-2.7
