Lehigh team develops new more effective carbon capture sorbent; seawater effective regenerant

Green Car Congress

In addition, similar to other amine-based sorbents, this hybrid sorbent is regenerable with waste heat or thermal energy at The desorbed CO 2 is simultaneously sequestered as innocuous baking soda (sodium bicarbonate, NaHCO 3 ). Concept of CO 2 sorption by polyamine-Cu(II) complex. Resources Hao Chen, Hang Dong, Zhongyu Shi and Arup K.

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.

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.

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.

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.
