Stage‐Specific Roles of Deep Eutectic Solvents in Recycling of Spent Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Deep eutectic solvents (DESs) offer tunable acidity, redox, and coordination properties for selective recycling of spent lithium‐ion battery cathodes. Through co‐dissolution, single‐ and two‐metal separations, DESs enable sustainable recovery of critical metals for closed‐loop regeneration of battery‐grade materials, advancing a circular economy for ...

Extending Battery Usage Time of a Heavy‐Duty Mecanum‐Wheeled Autonomous Electric Vehicle Used in Iron–Steel Industry by Considering Wheel Slippage

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
It is a fact that slippage causes tracking errors in both longitudinal and lateral directions which results to have less travel distance in tracking a reference trajectory. Less travel distance means having energy loss of the battery and carrying loads less than planned.

Modulating Li+ and Polysulfide Solvation with Low‐Density Moderately Solvating Electrolytes for Lithium–Sulfur Batteries

open access: yesAngewandte Chemie, EarlyView.
A low‐density, nonfluorinated moderately solvating electrolyte (MSE) composed of methyl tert–butyl ether concurrently tunes Li+ and polysulfide solvation, lowering desolvation barrier and mitigating polysulfide shuttling. It effectively stabilizes both electrodes and enables stable cycling of Li–S batteries under practical parameters at room ...
