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

French researchers develop sodium-ion battery in 18650 format; performance comparable to Li-ion

Green Car Congress

Researchers within the RS2E network on electrochemical energy storage (Réseau sur le stockage électrochimique de l’énergie) in France have developed the first sodium-ion battery in an 18650 format. The main advantage of the prototype is that it relies on sodium, an element far more abundant and less costly than lithium.

CATL launches “condensed battery” with an energy density of up to 500 Wh/kg for aircraft; automotive version this year

Green Car Congress

Currently CATL has an extensive technology roadmap for batteries, and has developed the capability to turn fundamental research to industrial application, and then to large-scale commercial applications. For example, in 2021, CATL rolled out the first generation of sodium-ion battery with an energy density of 160 Wh/kg.
