TL;DR: In this paper, a rational relation between GO sheet size and polydispersity, concentration, liquid crystallinity, and spinnability is proposed, leading to an understanding of lyotropic LC behavior and fiber spinnable.

TL;DR: In this article, a proof-of-concept study on the active site evaluation for a highly oriented pyrolytic graphite catalyst with specific pentagon carbon defective patterns (D-HOPG) is presented.

TL;DR: The use of Na4C8H2O6 as the initial active materials for both electrodes provided the first example of all-organic rocking-chair SIBs with an average operation voltage of 1.8 V and a practical energy density of about 65 Wh kg(-1) with excellent cycling.

TL;DR: In this paper, the fundamental principles and applications of Mg-air batteries are introduced and the design of electrode materials both for anodes and cathodes for further performance improvement is discussed.

TL;DR: Considering that the high capacity, long-term cycle life, and high-rate capability of anode materials for sodium-ion batteries (SIBs) is a bottleneck currently, a series of Co-doped FeS2 solid solutions with different Co contents were prepared by a facile solvothermal method, and for the first time their Na-storage properties were investigated.
