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. Na is comparable to graphite for standard lithium ion batteries. The estimated sodium storage up to C 6.9

Ricardo and QinetiQ Demonstrate New Iron-Sulphide Li-ion Pack for HEVs

Green Car Congress

The aim of the project was to develop an alternative Li-ion cell chemistry that could be integrated within an HEV using a bespoke battery management system. QinetiQ has also been working on lithium-ion/iron sulphide cells for a number of years. Click to enlarge. For use as a cathode material, the iron sulphide must be lithiated.
