A new tellurium‐based Ni ₃ TeO ₆ ‐carbon nanotubes composite anode for Na‐ion battery

Abstract

In this study, nickel tellurium oxide (Ni 3 TeO 6 ) was composited with carbon nanotubes (CNTs) through the high-energy ball-milling method and proposed as a high-energy conversion-type anode for sodium-ion batteries (SIBs) for the first time. Upon mechanical milling, the Ni 3 TeO 6 nanoparticles were uniformly encapsulated and wedged within the CNTs matrix, which produced a nano/micro hybrid structure. The interconnected CNT network in the composite provided conductive paths for rapid electron transport while effectively suppressing the local stress caused by large volume changes of Ni 3 TeO 6 during the sodiation-desodiation process. The Ni 3 TeO 6 @CNTs exhibited a high Na +ion storage capacity of 495 mA h g À1 , good cycling stability at 200 mA g À1 , and high-rate performance up to 2000 mA g À1 .

Hydrothermal Synthesis of Ni3TeO6 and Cu3TeO6 Nanostructures for Magnetic and Photoconductivity Applications

“…Three notable spin lattices, namely, equilateral triangle, isosceles triangle, and planar hexagon, are built by CuO 6 octahedra via corner-sharing or edge-sharing. Concerning the low-temperature AFM property, CTO adopts a bixbyite-type crystal structure and orders in a "three-dimensional spin web" with hexagonal arrangements of the magnetic moments below T N = 63 K. 3,11,12 Besides these reports, which mainly focus on magnetoelectric application, an additional report also explores the photocatalytic activity 13 and electrochemical properties 14 of NTO and their application as sensor of CTO, 15 While the role of transition metals in several transition metal-based complexes including MTO has been already been studied, 16 the role of tellurium (Te) in such compounds is still a paradox. Te, a chalcogenide high-Z element, has already provided great development potential in the fields of highperformance photodetectors, field effect transistors, and thermoelectric devices in recent years.…”

“…However, due to the low conductivity of the converted anode materials and the large volume change in the process of intercalation/deintercalation, their practical application has been hindered. Therefore, effective strategies to solve these problems have been explored through carbon recombination [53], core-shell structures [54], defect engineering [55], etc.…”
