Cobalt phosphide nanoparticles which were uniformly embedded in N-doped C nanosheets (CNSs) were prepared via the facile one-step calcination of a Co-based metal–organic framework (MOF) and red P, and the composite exhibited a high capacity, excellent rate performance, and a long cycle life. The outstanding performance of the composite is attributed to the P–C chemical interactions and highly conductive CNSs.

Trivalent titanium doped titania/carbon (TiO2–x/C) composite microspheres have been fabricated by a facile aerosol method. The obtained TiO2–x/C composite microspheres exhibit a high specific capacity (286 mA·h·g–1 at 50 mA·g–1) and excellent cycling stability (retaining 249 mA·h·g–1 after 180 cycles at 50 mA·g–1) in sodium storage.

Layered SnS nanosheets/carbon anodes were synthesized near room temperature using a simple one-step chemical bath deposition approach, followed by a solution-based carbon precursor coating and subsequent carbonization strategy. When used as sodium ion battery anodes, the as-prepared binder-free SnS/C electrodes showed excellent performance.

Ultra-fine SnO2 nanocrystals anchored on the well-interconnected, three-dimensional (3D) macro-porous reduced graphene oxide (rGO) matrix showed outstanding performance as bifunctional electrodes for Li-ion and Na-ion batteries. Insights obtained from in situ X-ray diffraction (XRD) measurements combined with various electrochemical techniques suggested that the conductive, 3D porous rGO matrix has a more significant impact on Na-ion batteries.
