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. While numerous other laboratories are also working on Na-ion batteries (e.g., a cylinder 18mm in diameter and 65mm in height, the.

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
