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. Earlier post.) —Stuart Licht. —Licht et al.

IBC demonstrates highly selective high-yield direct lithium extraction from Salar de Maricunga brine

Green Car Congress

Exceptionally high selectivity for lithium over other ions present in the brine (including sodium, potassium, magnesium, calcium, and boron), meeting specifications for subsequent direct production of battery-grade lithium hydroxide monohydrate, without the need to first produce lithium carbonate. g/L) and Ca (7.2 m3 per day.

Researchers develop all-weather solar cell that generates power from rain as well as from sun

Green Car Congress

While many technical advances have made solar cells more efficient and affordable, a disadvantage remains in the fact that solar cells produce no power when it’s raining. c), d) The operational principle of the flexible solar cell under sunlight. The droplets are injected by a medical syringe by controlling injection velocity.

DOE awards Cummins $5M for automation of electrolyzer cell and stack assembly

Green Car Congress

Proton exchange membrane (PEM) electrolyzers use a solid polymer electrolyte, and alkaline electrolyzers use an electrolyte solution, such as potassium hydroxide or sodium hydroxide mixed with water. When any type of electrolyzer is powered by renewable energy sources, such as wind, solar or hydro, it produces “green” hydrogen.

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.
