Researchers convert atmospheric CO2 to carbon nanofibers and nanotubes for use as anodes in Li-ion and Na-ion batteries

Green Car Congress

Researchers from George Washington University and Vanderbilt University have demonstrated the conversion of atmospheric CO 2 into carbon nanofibers (CNFs) and carbon nanotubes (CNTs) for use as high-performance anodes in both lithium-ion and sodium-ion batteries. —Stuart Licht. —Licht et al.

Graphene is a two-dimensional form of carbon in which the atoms are bonded into a honeycomb arrangement. Raindrops are not pure water; they contain salts that dissociate into positive and negative ions. The positively charged ions, including sodium, calcium, and ammonium ions, can bind to the graphene surface. Click to enlarge.

CMU study concludes lithium market fluctuations unlikely to impact Li-ion battery prices significantly

Green Car Congress

Furthermore, both lithium supply shortages and extreme price variations are frequently used as justifications for research on alternate cation electrochemical energy storage technologies such as sodium, magnesium, and potassium based systems. If prices do quadruple, it becomes, in principle, economical to extract lithium from sea water.

Researchers synthesize new Li-S cathode based on “carbon compartments”

Green Car Congress

Researchers from Texas A&M and Purdue have developed a new cathode material for Li-S batteries based on what they call carbon compartments (CCs)—conductive 3D carbon mesostructures that possess macro- and meso-pores that allow for high loading of sulfur nanoparticles and enhanced electrolyte-sulfur contact.

It was placed on care and maintenance by CBA in 2016, when CBA also placed its Niquelandia mine and processing plant in Brazil on care and maintenance due to prevailing market conditions at the time. Niquelandia provided the SMP Refinery with nickel carbonate. The facility is located in an industrial zone in São Paulo, Brazil.
