Chalmers team develops graphite-like anode for Na-ion batteries; Janus graphene

Green Car Congress

Researchers at Chalmers University of Technology, Sweden, have developed a nanometric graphite-like anode for sodium ion (Na + storage), formed by stacked graphene sheets functionalized only on one side, termed Janus graphene. The estimated sodium storage up to C 6.9 Na is comparable to graphite for standard lithium ion batteries.

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.

Study suggests lithium and cobalt for batteries may face supply risks by 2050

Green Car Congress

The researchers present these results in the journal Nature Reviews Materials as part of a cost and resource analysis of sodium-ion batteries. … However, at present, the use of cobalt is still often necessary for cathode materials with high energy density owing to its stabilizing effect in layered oxides (including NCM(622) and NCA).

Chinese steel group Tsingshan investing $375M to build lithium plant in Argentina with Eramet

Green Car Congress

It is a key milestone in the deployment of our strategic roadmap which aims at positioning Eramet as a reference player in metals for the energy transition. Developed by Eramet in liaison with IFPEN (the French Institute of Petroleum and New Energies) and Seprosys, this works like a sponge, capturing the lithium contained in the brine.

Univ. of Tokyo researchers demonstrate new “oxygen-rocking” battery

Green Car Congress

Researchers at the University of Tokyo have developed a battery based on the concept of a combination of a perovskite-type cathode and a low-electrode-potential anode that can achieve high energy densities through the use of organic rather than aqueous electrolytes. Earlier post.). FeO z , with 2.58 ? —Hibino et al.
