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. —Linda Nazar. Resources.

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. of peak charge capacity.

UP Catalyst CO2-derived carbon nanotube electrode material boosts cycle life in Na-ion batteries

Green Car Congress

The results showed 93.75% capacity retention after exceeding 4000 charge and discharge cycles. P Catalyst uses a molten salt carbon capture and electrochemical transformation method to reprocess the CO 2 -rich flue gases from heavy industry emitters, biogenic origin and even direct air captured (DAC) CO 2.

The Case for Nuclear Cargo Ships

Cars That Think

The European Union plans to begin charging shippers for carbon emissions this year. Researchers are considering three different types: a lead-cooled fast reactor, a uranium-fueled, helium-gas-cooled reactor, and a molten-salt-cooled reactor, shown here [below, at bottom]. One is a thorium-fueled molten-salt reactor.

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. But this particular salt, it happens, is very good at preventing that malfunction.

Energy storage: the key to a decarbonised future

Setec Powerr

Technologies include energy storage with molten salt and liquid air or cryogenic storage. Molten salt has emerged as commercially viable with concentrated solar power but this and other heat storage options may be limited by the need for large underground storage caverns.
