In situ Interweaved Binder Framework Mitigating the Structural and Interphasial Degradations of High‐nickel Cathodes in Lithium‐ion Batteries

cathodes achieve 0.02 % capacity decay per cycle at 1 C rate over 1 000 deep cycles at 4.4 V (vs. graphite). This work demonstrates a rational structural and compositional design strategy of polymer binders to mitigate the structural and interphasial degradations of high-Ni cathodes in lithium-ion batteries.
