Copper Contact for Perovskite Solar Cells: Properties, Interfaces, and Scalable Integration

Advanced Energy and Sustainability Research, EarlyView.
Copper electrodes, as low‐cost, scalable contacts for perovskite solar cells, offer several advantages over precious metals such as Au and Ag, including performance, cost, deposition methods, and interfacial engineering. Copper (Cu) electrodes are increasingly considered practical, sustainable alternatives to noble‐metal contacts in perovskite solar ...

Atomic Level Fabrication of Oxychloride Interface for High‐Rate and High‐Voltage Lithium‐Ion Batteries

Angewandte Chemie, EarlyView.
Synthesis of a lithium‐ion conductive aluminum‐based oxychloride (LAOC) thin film is realized by a facile atomic‐level chemical fabrication method. LAOC coating enables lithium cobalt oxide (LCO) cathode superior cycling performance at high rates and elevated voltages, owing to the fast interfacial ionic transport and excellent interfacial stability ...

Redox‐Mediated Electrochemical Regeneration of Spent LiFePO4 Battery Cathodes

Angewandte Chemie, EarlyView.
This work demonstrates a redox‐mediated electrochemical method for direct recycling of spent LiFePO4 battery cathodes. A water‐soluble mediator, iron propylenediamine tetraacetate (Fe‐PDTA), transports electrons into an off‐electrode reservoir where it drives compositional and structural repair of degraded LiFePO4.

Core‐Shell: Resolving the Dilemma of Hard Carbon Anodes by Sealing Nanoporous Particles With Semi‐Permeable Coatings

Angewandte Chemie International Edition, EarlyView.
A core–shell strategy is presented to overcome the high first‐cycle losses of non‐graphitic hard carbon anodes. Activated carbon is sealed by gas‐phase carbon deposition to create semi‐permeable shells that spatially separate SEI formation from Na storage in a retained nanoporous core. The resulting anode delivers 400 ± 24 mAh g−1 with an ICE of 82 ± 2%
