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. Structural schematic of a Li/LFP cell with the ETG as electrolyte. V versus Li, and unable to stop the growth of lithium dendrites.

Researchers demonstrate high-capacity Mn-rich Li-ion cathodes; a design pathway away from cobalt and nickel

Green Car Congress

Researchers led by a team at UC Berkeley have demonstrated high-capacity manganese-rich cathodes for advanced lithium-ion batteries. Low cost and low toxicity make the Mn 2+ /Mn 4+ couple particularly desirable for designing high-performance Li-ion batteries that are also inexpensive and eco-friendly. …

Study shows paper-folding concepts can compact a Li-ion battery and increase its areal energy density

Green Car Congress

Researchers at Arizona State University have shown that paper-folding concepts can be applied to Li-ion batteries in order to realize a device with higher areal energy densities. These initial results showed that the Li-ion batteries can still exhibit good electrochemical performance even after multiple folds, they said.

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

Ford and Samsung outline R&D efforts for next-generation non-hybrid battery technology; dual-battery systems and lightweight Li-ion

Green Car Congress

For the near term, they have been working on a dual-battery combining a lithium-ion battery with a 12-volt lead-acid battery that could enable regenerative braking technology in non-hybrid vehicles for greater fuel savings. The research advances lithium-ion battery technology currently available on Ford’s electrified vehicles.
