INL, UCSD researchers find slow, low-energy charging of Li batteries creates glassy lithium; high-performance Li-metal batteries

Green Car Congress

The findings suggest strategies for fine-tuning recharging approaches to boost battery life and—intriguingly—for making glassy metals for other applications. Compared to crystalline Li, glassy Li outperforms in electrochemical reversibility, and it has a desired structure for high-energy rechargeable Li batteries.

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

Green Car Congress

Up until now, Li-ion batteries have been considered to exhibit no “memory effect”—a deviation in the voltage of the battery resulting from repeated charging after being only partially discharged that can limit the usability of the stored energy as well as the ability to determine the state of charge of the battery reliably.

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%.”
