Altris presents high-capacity Prussian White cathode material for Na-ion batteries; 160 mAh/g

Green Car Congress

Swedish sodium-ion battery developer Altris presented a pure Prussian White cathode material with a capacity of 160 mAh/g, making it the highest capacity declared to date. Prussian White is a framework material consisting of sodium, iron, carbon and nitrogen (Na x Fe[Fe(CN) 6 ] with x>1.9). Earlier post.)

Researchers show that inherent lithium ions in bioderived borate polymer enhance extreme fast charging capability in graphite anodes

Green Car Congress

Anodic half-cells with the novel binder delivered a discharge capacity of 73 mAh/g at 10 C, which is three times higher than the those of the polyvinylidene fluoride (PVDF) and sodium carboxymethyl cellulose/polystyrene-polybutadiene rubber (CMC-SBR) counterparts, with a high capacity retention for more than 1000 cycles. —Pradhan et al.

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 6.9 100 to 150 mA h g ? 100 to 150 mA h g ?1

New Na-ion battery combining intercalation and conversion could be promising low-cost energy storage system

Green Car Congress

Scheme of the new full sodium-ion battery, which combines an intercalation cathode and a conversion anode. Mn 0.25 ]O 2 layered cathode (NFM), and NaClO 4 in fluoroethylene carbonate and ethyl methanesulfonate electrolyte. For the anode, they selected carbon-modified iron oxide (C-Fe 3 O 4 ) conversion material.
