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 ...

Al‐Doped LaTiO2N Prepared via Flame Spray Pyrolysis for Photocatalytic Hydrogen Evolution

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Flame spray pyrolysis enables the synthesis of La–Ti oxides with a simple perovskite‐type structure, and Al doping promotes the formation of the simple perovskite‐type La–Ti oxides. The Al‐doped LaTiO2N obtained by nitridation has a reduced defect concentration due to suppressed structural change, which contributes to the improvement of hydrogen ...
