1D Building Blocks-Intermingled Heteronanomats as a Platform Architecture For High-Performance Ultrahigh-Capacity Lithium-Ion Battery Cathodes.

The cathode active particles‐embedded polyacrylonitrile nanofibers/multiwalled carbon nanotubes heteronanomat cathode (HM cathode) is demonstrated as an effective and versatile electrode platform to address the long‐standing challenges of conventional cathodes. The material/structure uniqueness of the HM cathode enables substantial improvements in rate capability, cycling performance and, most notably, areal capacity far beyond those accessible with conventional cathode technologies.
