Interlayer‐Expanded Titanate Hierarchical Hollow Spheres Embedded in Carbon Nanofibers for Enhanced Na Storage (Small 16/2022). Issue 16 (21st April 2022) - Chen, Chong
Abstract : Sodium-Ion Capacitors In article number 2107890, Jieshan Qiu, Le Yu, and co‐workers report the design of magnesium titanate hierarchical hollow spheres embedded in carbon nanofibers by electrospinning for sodium‐ion capacitors (NICs). Three‐dimensional conductive carbon framework together with the expanded interlayer spacing of titanate hierarchical hollow spheres via the pillared Mg 2+ ions expose more active sites for fast kinetics and enable superior rate performance for the long‐term cycling of the assembled NIC device.
