MIT team develops data-driven safety envelope for lithium-ion batteries for EVs

Green Car Congress

Researchers at MIT, with a colleague from Tsinghua University, have developed a safety envelope for Li-ion batteries in electric vehicles by using a high accuracy finite element model of a pouch cell to produce more than 2,500 simulations and subsequently analyzing the data with Machine Learning (ML) algorithms. —Li et al.

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 —Sun et al.

New Lithium-intercalated graphene materials good candidates for Li-ion battery applications

Green Car Congress

Variation in discharge capacity vs. cycle number for graphite, RGO, and Li-RGO cycled at a current rate of 25 mA/g between 3.0 V vs Li/Li +. Cyclic voltammograms (CV) of the Li-RGO electrode demonstrated that lithium could reversibly intercalate and deintercalate into graphene sheets. Credit: ACS, Kumar et al.
