A series of glass cathode materials [Formula: see text]Li2O–50V2O5–(50−[Formula: see text])P2O5 ([Formula: see text], 25, 30, 35 and 40) have been synthesized by a simple melting–quenching method. 30Li2O–50V2O5–20P2O5 glass (LVP30) shows the best cycling performance with a preferable capacity retention after 50 cycles. Then, we prepared a series of carbon-coated LVP30 glass-ceramic cathode materials by carbon coating and heat treatment. The carbon-coated LVP30 samples consist of the crystalline phase V2O3, VO2 and Li2O–V2O5–P2O5 glass. Among the carbon-coated LVP30 samples, LVP30-15C sample exhibits the best cycling and rate performance. It can retain a discharge capacity of 140[Formula: see text]mAh[Formula: see text]g[Formula: see text] after 100 cycles. This unique glass-ceramic structure can result in good conductivity and structural ductility.

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.
