Cathodes: 1D Building Blocks‐Intermingled Heteronanomats as a Platform Architecture For High‐Performance Ultrahigh‐Capacity Lithium‐Ion Battery Cathodes (Adv. Energy Mater. 2/2016)

In article number 1501594, Sang-Young Lee and co-workers demonstrate a heteronanomat cathode (HM cathode) as an effective and versatile electrode platform to address the long-standing challenges of conventional cathodes. The HM cathode is fabricated via a simultaneous electrospraying and electrospinning process without the use of binders, carbon powder additives, or metallic foil current collectors. The material/structural uniqueness of the HM cathode provides substantial improvements in redox reaction kinetics, cycling performance and ultrahigh-areal capacity far beyond those achievable with conventional cathode technologies.
