TL;DR: In this article, a three-dimensional macroporous carbon film composed of interwoven connected carbon fibers containing around 10wt% oxygen and 8 wt% nitrogen was synthesized by carbonizing a common livestock biowaste in the form of chicken eggshell membranes.
Abstract: Supercapacitor electrode materials are synthesized by carbonizing a common livestock biowaste in the form of chicken eggshell membranes. The carbonized eggshell membrane (CESM) is a three-dimensional macroporous carbon film composed of interwoven connected carbon fibers containing around 10 wt% oxygen and 8 wt% nitrogen. Despite a relatively low surface area of 221 m2 g−1, exceptional specific capacitances of 297 F g−1 and 284 F g−1 are achieved in basic and acidic electrolytes, respectively, in a 3-electrode system. Furthermore, the electrodes demonstrate excellent cycling stability: only 3% capacitance fading is observed after 10 000 cycles at a current density of 4 A g−1. These very attractive electrochemical properties are discussed in the context of the unique structure and chemistry of the material.
TL;DR: Under the characterization measurements investigated, it was found that the pore structures of the two biomaterials belong to a typical Type II, indicating that they should be basically characteristic of nonporous materials or materials with macropores or open voids.
TL;DR: This design with CSEM allows the dissolved polysulfides to be localized and the electrochemical reactions within the cathode region to be stabilized, resulting in high discharge capacity, long-term cycle stability, and high sulfur loading.
Abstract: Carbonized sucrose-coated eggshell membranes (CSEMs) consisting of natural micropores function well as a polysulfide reservoir in Li/dissolved polysulfide cells. The bottom CSEM current collector encapsulates the active material, while the upper CSEM inhibitor intercepts the migrating polysulfides. This design with CSEM allows the dissolved polysulfides to be localized and the electrochemical reactions within the cathode region to be stabilized, resulting in high discharge capacity, long-term cycle stability, and high sulfur loading.
TL;DR: In this article, a feasible and low-cost method has been developed to synthesize an effective carbon-based microwave absorber, which achieved the maximum reflection loss value of −49.6 dB at 9.2 GHz with 30% loading in the paraffin matrix.
