New Na-ion battery combining intercalation and conversion could be promising low-cost energy storage system

Green Car Congress

Scheme of the new full sodium-ion battery, which combines an intercalation cathode and a conversion anode. Mn 0.25 ]O 2 layered cathode (NFM), and NaClO 4 in fluoroethylene carbonate and ethyl methanesulfonate electrolyte. For the anode, they selected carbon-modified iron oxide (C-Fe 3 O 4 ) conversion material.

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

Green Car Congress

Researchers from Ulsan National Institute of Science and Technology (UNIST) in Korea and Karlsruher Institute of Technology in Germany have developed a novel energy conversion and storage system using seawater as a cathode. Similarly, sodium has recently attracted attention as a replacement for lithium in alkali-metal-air batteries.

Isfahan University of Tech team reports new efficient pretreatment method for rice straw to boost yield of cellulosic ethanol

Green Car Congress

Researchers at Isfahan University of Technology (Iran) report the efficient production of cellulosic ethanol from rice straw using a new sodium carbonate pretreatment method. Rice straw was treated with sodium carbonate (Na 2 CO 3 )prior to enzymatic hydrolysis and fermentation. and 1 M sodium carbonate solution.

Converting Coal Power Plants to Nuclear Gains Steam

Cars That Think

On a planet aspiring to become carbon neutral, the once-stalwart coal power plant is an emerging anachronism. Department of Energy (DOE) released a report suggesting that, in theory, over 300 former and present coal power plants could be converted to nuclear. Conversion backers say the process has benefits for everybody involved.

Researchers Develop Lithium-Water Electrochemical Cell for the Controlled Generation of H2 and Electricity

Green Car Congress

Although direct chemical reactions between water and certain metals—alkali metals including lithium, sodium and others—can produce a large amount of hydrogen in a short time, these reactions are too intense to be controlled. the high-school chemistry demonstration of the violent reaction between sodium and water.).
