Chemical vapor deposition and filtration are commonly used to fabricate freestanding multiwalled carbon nanotube sheets containing iron(III) oxide (Fe2O3) (MWCNT–Fe2O3 sheets). However, the former is relatively expensive, and the latter suffers from poor scalability. Here, the authors develop an inexpensive, scalable, high‐throughput, tunable tape‐casting method for fabricating flexible, foldable freestanding MWCNT–Fe2O3 sheets. When tested as electrodes in lithium‐ion batteries, the sheets…

Nanoscopic and Macro-Porous Carbon Nano-foam Electrodes with Improved Mass Transport for Vanadium Redox Flow Batteries

A method to fabricate high performance macro-porous carbon nano-foam free standing sheets (Puffy Fibers), by implementing a freeze-drying step into the low cost and scalable surface-engineered tape-casting (SETC) fabrication method, and an electrolytic transport mechanism to relate ion diffusivity to different pore sizes to explain the different modes of charge transfer in the negative and the positive electrolytes.

Three-Dimensional Monolithic Organic Battery Electrodes.

Design of freestanding electrodes incorporated with redox-active organic materials has been limited by the poor intrinsic electrical conductivity and lack of methodology driving the feasible
