Abstract

Abstract : In article number 2002837, Sang‐Young Lee and co‐workers present a 3D bicontinuous heterofibrous network scaffold (HNS), consisting of single‐walled carbon nanotubes and cellulose nanofibers as a new electrode architecture for rechargeable aqueous ZnMnO2 batteries. The HNS allows the formation of bicontinuous electron/ion conduction pathways, thereby facilitating the redox kinetics of MnO2 . Consequently, the HNS‐based MnO2 electrode offers exceptional improvements in energy/power densities.
