Abstract
Nanocavity-enriched Co3O4@ZnCo2O4@NC porous nanowires have been successfully prepared by a two-step annealing process of one-dimensional (1D) coordination polymer precursors. Such unique nanowires with nanocavity-based porous channels can provide a large specific surface area, which allows fast electron/ion transfer and alleviates the volume expansion caused by strain during the charge/discharge processes. While used as the anode material of lithium-ion batteries (LIBs), Co3O4@ZnCo2O4@NC electrodes exhibit outstanding rate capacity and cycling stability, such as a high reversible capacity of 931 mA h g-1 after 50 cycles at a current density of 0.1 A g-1 and a long-term cycling efficiency of 649 mA h g-1 after 600 cycles at 1 A g-1. This coordination polymer template method lays a solid foundation for the design and preparation of bimetal oxide materials with outstanding electrochemical performance for LIBs.

The Carbon-Coated ZnCo2O4 Nanowire Arrays Pyrolyzed from PVA for Enhancing Lithium Storage Capacity. Processes (Basel) 2020.

Abstract
In this paper, ZnCo2O4 nanowire arrays with a uniform carbon coating were introduced when polyvinyl alcohol (PVA) served as the carbon source. The coating process was completed by a facile bath method in PVA aqueous solution and subsequent pyrolyzation. The PVA-derived carbon-coated ZnCo2O4 nanowire array composites can be used directly as the binder-free and self-supported anode materials for lithium-ion batteries. In the carbon-coated ZnCo2O4 composites, the carbon layer carbonized from PVA can accelerate the electron transfer and accommodate the volume swing during the cycling process. The lithium storage properties of the carbon-coated ZnCo2O4 composites are investigated. It is believed that the novel carbon-coating method is universal and can be applied to other nanoarray materials.
