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

24M emerges from stealth mode with new semi-solid Li-ion cell; <$100/kWh by 2020

Green Car Congress

Stealth-mode battery start-up 24M has introduced its new semi-solid lithium-ion cell. Together, our inventions achieve what lithium-ion has yet to do—meet the ultra-low cost targets of the grid and transportation industries. The lithium-ion battery is a brilliant, enabling technology, but its economics are flawed.

Paul Scherrer Institute and Toyota RD team finds tiny memory effect in Li-ion batteries; implications for vehicle battery management systems

Green Car Congress

The memory effect of the battery is written in a cycle with partial charging (here, 50% of the battery’s storage capacity) followed by complete discharge. In the subsequent cycle, the memory effect is evident through an overvoltage (small “bump”) at precisely the same point at which the partial charging cycle terminates. Sasaki et al.

Li-Ion Battery Researchers Work To Improve Precision Measurements of Charging, Estimations of Cycle Life; Highlight Need For Further Order of Magnitude Improvement In Accuracy

Green Car Congress

Researchers at Dalhousie University in Halifax, Nova Scotia have called for new tools that can more accurately measure an electrochemical cell’s Coulombic efficiency (CE) when evaluating cycle life of lithium-ion cells as well as other battery chemistries. Such CE measurements would have to be precise on the scale of at least ±0.01%.”
