Abstract

Defect engineering has been used for centuries to enhance the mechanical strength of metals and alloys, but its application to cathodes remains largely unexplored. Conventional cathode synthesis aims for defect-free crystals to maximize capacity, but such structures degrade easily through interlayer gliding and microcracking, both of which are reported for single-crystal LiNi 0.8 Mn 0.1 Co 0.1 O 2 (SC-NMC811). Dopant substitution or surface coating has been explored to address these issues but introduce foreign elements that complicate recycling. Here, we present a scalable method to introduce a controlled amount (
