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. —Sun et al.

Researchers in Belgium develop new class of solid composite electrolytes for Li-ion batteries: Eutectogels

Green Car Congress

Researchers at Hasselt University in Belgium are proposing a new class of solid composite electrolytes (SCEs) for Li-ion batteries: deep eutectic solvent (DES)–silica composites. The DES-based gel electrolytes—to which the team refers as eutectogels (ETGs)—are characterized by high ionic conductivity (1.46 Joos et al. …
