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.

KAUST uses laser pulses to boost performance of MXene electrode

Green Car Congress

These nanodots, roughly 10 nanometers wide, were connected to the MXene’s layers by carbon materials. Finally, strong connections between the nanodots and the layers improve the MXene’s conductivity and stabilize its structure during charging and discharging. This offers several benefits. for pristine) over 1000 cycles. Alhajji, E.,

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

Green Car Congress

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. The battery installation is connected to a nearby 11-megawatt wind farm owned by Minwind Energy, LLC. A final report is expected in summer 2011.
