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.) Earlier post.)

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.

Hollow carbon nanowires show high capacity and cycle life as anodes for sodium-ion batteries; insight into Na-ion insertion-extraction mechanism

Green Car Congress

Researchers at the Pacific Northwest National Laboratory have developed hollow carbon nanowires (HCNWs) for use as anode material for Na-ion batteries. The researchers attributed the good sodium-ion insertion properties to the short diffusion distance in the HCNWs and the large interlayer distance (0.37 Credit: ACS, Cao et al.

Xcel Terms First Phase of Sodium-Sulfur Battery Wind Energy Storage Test Project Successful

Green Car Congress

Xcel Energy has released the preliminary results from its wind-to-battery (W2B) storage project in Minnesota, and termed the technology successful. In October 2008, Xcel began testing a one-megawatt sodium-sulfur (NaS) battery ( earlier post ) to demonstrate its ability to store wind energy and move it to the electricity grid when needed.

KAUST uses laser pulses to boost performance of MXene electrode

Green Car Congress

The researchers hope that this strategy could help to engineer an improved anode material in next-generation batteries. Graphite contains flat layers of carbon atoms, and during battery charging, lithium atoms are stored between these layers in a process called intercalation. A paper on their work is published in the journal Small.
