“…The broad bump and low diffraction peaks imply that the synthesized ZnSb nanowires are in weak crystallinity. This feature is similar to other works of Zinc antimony, in which the nanostructures usually crystallize weakly or even in amorphous phase [16,21]. Noticeable, there is tiny ZnO in the sample as confirmed by the XRD result.…”

The development of new anode materials having high electrochemical performances and interesting reaction mechanisms is highly required to satisfy the need for long-lasting mobile electronic devices and electric vehicles. Here, we report a layer crystalline structured SnP3 and its unique electrochemical behaviors with Li. The SnP3 was simply synthesized through modification of Sn crystallography by combination with P and its potential as an anode material for LIBs was investigated. During Li insertion reaction, the SnP3 anode showed an interesting two-step electrochemical reaction mechanism comprised of a topotactic transition (0.7–2.0 V) and a conversion (0.0–2.0 V) reaction. When the SnP3-based composite electrode was tested within the topotactic reaction region (0.7–2.0 V) between SnP3 and LixSnP3 (x ≤ 4), it showed excellent electrochemical properties, such as a high volumetric capacity (1st discharge/charge capacity was 840/663 mA h cm−3) with a high initial coulombic efficiency, stable cycle behavior (636 mA h cm−3 over 100 cycles), and fast rate capability (550 mA h cm−3 at 3C). This layered SnP3 anode will be applicable to a new anode material for rechargeable LIBs.

“…The poor capacity retention of the ZnTe electrode may be caused by the large volume change that occurs on the formation of Li 2 Te and LiZn phases during the discharge step, followed by pulverization of the active material and its subsequent electrical isolation from the current collector. [36][37][38][39][40][41][42] In Fig. 3a and b, the DCP and CV of the first and second cycles of the ZnTe electrode show several peaks during its discharge and charge reactions.…”

ARTICLE This journal isZinc telluride (ZnTe) and a nanostructured ZnTe/C composite were prepared by a simple solidstate synthetic route and their potential as electrode materials for rechargeable Li-ion batteries was investigated. The electrochemical conversion/partial recombination reactions between ZnTe and Li were determined using ex situ X-ray diffraction and extended X-ray absorption fine structure analysis. X-ray diffraction and high-resolution transmission electron microscopy confirmed that the ZnTe/C nanocomposite consisted of ZnTe nanocrystallites that were uniformly distributed within an amorphous carbon matrix. The nanostructured ZnTe/C composite electrode exhibited excellent electrochemical properties with a high capacity (1st charge: 530 mAh g -1 ), cycling durability (over 200 cycles), and fast rate capability (1C: ca. 550 mAh g -1 , 3C: ca. 504 mAh g -1 ).
