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 this work we explore the sodium and lithium conversion of ultrafine FeS 2 nanoparticles, with a tight size distribution centered around ∼4.5 nanometers in size.

Aqua Metals is building a more sustainable battery recycling ecosystem

Charged EVs

The economic benefits of recycling Li-ion batteries are clear, but at present, only a small percentage of them are recycled. In contrast, lead-acid batteries have a 99% recycling rate in the US. The two main processes for recycling lithium-ion batteries are pyrometallurgy and hydrometallurgy.

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.

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.
