Elastomeric Core‐Conductive Shell Slurry Additive Stabilizes High‐Voltage NCM811 Cathodes via Mechanical‐Electrical Dual Regulation

Advanced Science, EarlyView.
A core‐shell ASA slurry additive constructs a mosaic‐like interface on high‐voltage NCM811 cathodes. This architecture decouples interfacial functions: the elastomeric core buffers mechanical stress to prevent microcracking, while the conductive shell facilitates rapid ion/electron transport, enabling mechanical‐electrical dual regulation and enhanced ...
