"Wet spinning of hollow graphene fibers with high capacitance" by Kezhong Wang, Yunfeng Chao et al.

Herein, we report a facile coaxial wet-spinning strategy to continuously produce hollow graphene fibers (HGF) with the merits of high conductivity, excellent flexibility, and enhanced electrode–electrolyte contact. The hollow structure is achieved by introducing reductant-containing coagulant solution into the fiber core with a composition identical to the spinning bath. The produced fibers were assembled into a supercapacitor device with an ultra-high specific capacitance of 711 mF/cm2 (i.e. 33.5 mF/cm or 190F/cm3). The combination of outstanding electrochemical and mechanical properties makes this HGF a promising candidate for use in wearable supercapacitors and electronics. ....

"Recent Progress of Conductive Metal–Organic Frameworks for Electrochem" by Zhiyuan Sang, Yueyu Tong et al.

The development of reliable and low-cost energy storage systems is of considerable value in using renewable and clean energy sources, and exploring advanced electrodes with high reversible capacity, excellent rate performance, and long cycling life for Li/Na/Zn-ion batteries and supercapacitors is the key problem. Particularly because of their diverse structure, high specific surface area, and adjustable redox activity, electrically conductive metal–organic frameworks (c-MOFs) are considered promising candidates for these electrochemical applications, and a detailed overview of the recent progress of c-MOFs for electrochemical energy storage and their intrinsic energy storage mechanism helps realize a comprehensive and systematic understanding of this progress and further achieve highly efficient energy storage and conversion. Herein, the chemical structure of c-MOFs and their conductive mechanism are first introduced. Subsequently, a comprehensive summarization of the current applic ....

"Graphene-based fiber for energy and health" by Kezhong Wang

Portable, wearable and implantable medical devices that chronically monitor or communicate with the nervous system are indispensable in healthcare. Currently the development of these versatile devices is limited by two bottlenecks: functional microelectrodes to communicate with central and peripheral nervous systems and the power sources to drive the devices. The microelectrode needs to be flexible, capable of delivering high charge capacity and inducing minimal immune rejection response. In addition to the need for high energy density, the power supply should be flexible and robust enough to accommodate the volume and shape requirements of the electronic devices, and deformable to be adapted with human movements.
Graphene fiber (GF) is a microscopic carbonaceous fiber composed of nanoscopic graphene sheets with highly ordered structure. It is a promising candidate for wearable and implantable electronics due to its robustness and flexibility, high surface area and charge injection ....
