TL;DR: Expanded graphite is reported as a Na-ion battery anode, prepared through a process of oxidation and partial reduction on graphite, which has an enlarged interlayer lattice distance yet retains an analogous long-range-ordered layered structure to graphite.

TL;DR: In this article, the electrochemical performance of mesoporous carbon (C)/tin (Sn) anodes in Na-ion and Li-ion batteries is systematically investigated, showing that the desodiation potential of Sn anodes is approximately 021 V lower than delithiation potential, due to the large Na ion size and large volume change of porous C/Sn composite anode during alloy/dealloy reactions.

TL;DR: Because of the efficient 1D sodium-ion transport pathway and the highly conductive network of SbNP@C, the electrode preserved high overall capacities even when cycled at high currents, extending its usability to high power applications.

TL;DR: An aerosol spray pyrolysis technique is demonstrated, as a facile and scalable method, to synthesize a nano-Sn/C composite with uniformly dispersed 10 nm nano- Sn within a spherical carbon matrix, which can provide high rate performance for Sn anodes.

TL;DR: In this paper, the cycling performance of graphite anode in K-ion batteries is demonstrated with a reversible capacity of 246 mAh g/1 and 89% retention of the initial capacity after 200 cycles.
