Argonne researchers find cathode material synthesis a key reason for performance degradation of sodium-ion batteries

Green Car Congress

One of the more promising candidates for batteries beyond the current standard of lithium-ion materials is the sodium-ion (Na-ion) battery. Na-ion is particularly attractive because of the greater abundance and lower cost of sodium compared with lithium. In addition, when cycled at high voltage (4.5

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.

nm, average) of iron pyrite (FeS 2 ) nanoparticles are advantageous to sustain reversible conversion reactions in sodium ion and lithium ion batteries. In the paper, they reported reversible capacities of more than 500 and 600 mAh/g for sodium and lithium storage for ultrafine nanoparticles, along with improved cycling and rate capability.

CO2-neutral hydrogen storage with a bicarbonate/formate system

Green Car Congress

Practical hydrogen storage materials must take up and give off hydrogen at standard pressure and room temperature; accommodate a large amount of hydrogen in as little space as possible; and release it rapidly and on-demand. The nontoxic aqueous solution of formate is easily stored and transported. —Matthias Beller.

Fresh water is then used to release the stored lithium. Purification of the lithium, then reaction with sodium carbonate to convert it to lithium carbonate. All Eramet’s CSR standards will be applied on the activity. Once filtered again and washed, it achieves the chemical quality of the finished product.

Rio Tinto commits $2.4B for Jadar lithium project; planning 58,000 tons/year lithium carbonate by 2029

Green Car Congress

The Jadar project would support the evolution of Rio Tinto—one of the world’s largest miners—into a chemical producer to make battery-grade lithium carbonate, a critical mineral used in large-scale batteries for electric vehicles and storing renewable energy.

New solid hydrogen-on-demand fuel cell from HES Energy Systems flies UAV for record 6 hours

Green Car Congress

Besides achieving a significant technical and performance milestone for hydrogen-on-demand enabled fuel cells, it is also the first time that a fuel cell has moved beyond the prototype stage and entered the standard products list of a UAV manufacturer. It took HES several years to achieve this performance.
