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.

Researchers improve the performance of sodium-ion batteries by using tailored carbon anodes with hierarchical porosity

Green Car Congress

Researchers at Justus Liebig University, Giessen, Germany, have improved the performance of sodium-ion batteries ( earlier post ) by using tailor-made carbon materials with hierarchical porosity for the anode instead of common carbon-based anode materials.

WUSTL team develops high-power direct borohydride fuel cells; double the voltage of conventional H2 fuel cells

Green Car Congress

We identify an optimal flow regime range, broadly applicable to other liquid-fed fuel cells, in terms of the standard dimensionless Reynolds number (Re) and the Damkohler number (Da). By following our guidelines, even current, commercially deployed liquid fuel cells can see gains in performance. times higher power density at 1.5
