Sodium Niobate with a Large Interlayer Spacing: A Fast-Charging, Long-Life, and Low-Temperature Friendly Lithium-Storage Material.

Niobate Li -storage anode materials with shear ReO crystal structures have attracted intensive attention due to their inherent safety and large capacities. However, they generally suffer from limited rate performance, cyclic stability, and temperature adaptability, which are rooted in their insufficient interlayer spacings. Here, sodium niobate (NaNb O ) micron-sized particles are developed as a new anode material owning the largest interlayer spacing among the known shear ReO -type niobates.

Carbon-Coated CuNbO as A New Anode Material for Lithium Storage.

Niobates are very promising anode materials for Li-storage rooted in their good safety and high capacities. However, the exploration of niobate anode materials is still insufficient. In this work, we explore ~1 wt% carbon-coated CuNbO microparticles (C-CuNbO) with a stable shear ReO structure as a new anode material to store Li.
