U Waterloo team shows four-electron conversion for Li-O2 batteries for high energy density; inorganic molten salt electrolyte, high temperature

Green Car Congress

The new work, published in Science , shows that four-electron conversion for lithium-oxygen electrochemistry is highly reversible. The Waterloo team is the first to achieve four-electron conversion, which doubles the electron storage of lithium-oxygen, also known as lithium-air, batteries. Resources. —Linda Nazar.

New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

The new sodium-based molten salt battery uses two distinct reactions. The team previously reported a neutral molten salt reaction. The new discovery shows that this neutral molten salt can undergo a further reaction into an acidic molten salt. Resources J. Mark Weller, Minyuan M.

Estonian startup UP Catalyst secures €2.09M; sustainable carbon nanomaterials and graphite from CO2

Green Car Congress

This has a major negative impact on the environment as they are either mined or synthesized from energy-dense fossil resources. UP Catalyst uses a molten salt carbon capture and electrochemical transformation method to reprocess the CO 2. separation of products and collection.

Researchers propose new aluminum–sulfur battery with molten-salt electrolyte; low-cost, rechargeable, fire-resistant, recyclable

Green Car Congress

An international team of researchers led by Quanguan Pang at Peking University and Donald Sadoway at MIT reports a bidirectional, rapidly charging aluminum–chalcogen battery operating with a molten-salt electrolyte composed of NaCl–KCl–AlCl 3. A paper on the work is published in Nature.

Stanford team devises new bio-inspired strategy for using CO2 to produce multi-carbon compounds such as plastics and fuels

Green Car Congress

In the paper in Nature they showed that intermediate-temperature (200 to 350 ˚C) molten salts containing caesium or potassium cations enable carbonate ions (CO 3 2– ) to deprotonate very weakly acidic C–H bonds, generating carbon-centered nucleophiles that react with CO 2 to form carboxylates.

Convert Oil Wells to Solve the Solar Storage Problem

Cars That Think

The idea, says Daniel Codd , a researcher in renewable energy systems at the University of California, San Diego, is to store solar-produced heat in rock formations below the surface, creating a solar-charged geothermal resource in which heat is stored for meaningful durations. But we can still reduce the carbon [cost] of that oil.”
