Toward Complete CO2 Electroconversion: Status, Challenges, and Perspectives

open access: yesAdvanced Energy Materials, EarlyView.
Electrocatalytic CO2 reduction and CO2 batteries face challenges in achieving complete CO2 conversion with high conversion rates and Faradaic efficiency simultaneously. Existing systems compromise one for the other with incomplete CO2 conversion and inefficiencies, hindering practical applications. This perspective highlights state‐of‐the‐art progress,

Innovative Approach to Recycle Lithium‐Ion Battery Electrolytes via Sequential Chemical Processes

open access: yesAdvanced Energy Materials, EarlyView.
A chemical separation method is developed to recycle and purify nonaqueous electrolytes from spent lithium‐ion batteries. The new process consists of a sequence of precipitation in tandem with each distillation and solvent‐assisted vacuum extraction to obtain high‐quality electrolyte precursors.

Cathode Upcycling for Direct Recycling of Lithium‐Ion Batteries Using a Precipitation Approach

open access: yesAdvanced Energy Materials, EarlyView.
To improve the circularity of lithium‐ion batteries, researchers develop a low‐cost method to increase the energy density of directly recycled cathodes. Through a precipitation process, low‐nickel materials are converted to high‐nickel compositions. Using synchrotron 3D X‐ray imaging and diffraction, they track nickel diffusion during high‐temperature ...
