Carbon nanotubes (CNTs) with excellent electron conductivity are widely used to improve the electrochemical performance of the SnO anode. However, the chemical bonding between SnO and CNTs is not clearly elucidated despite it may affect the lithiation/delithiation behavior greatly. In this work, an SnO @CNT composite with SnC and SnOC bonds as a linkage bridge is reported and the influence of the SnC and SnOC bonds on the lithium storage properties is revealed. It is found that the SnC bond can act as an ultrafast electron transfer path, facilitating the reversible conversion reaction between Sn and Li O to form SnO . Therefore, the SnO @CNT composite with more SnC bond shows high reversible capacity and nearly half capacity contributes from conversion reaction. It is opposite for the SnO @CNT composite with more SnOC bond that the electrons cannot be transferred directly to CNTs, resulting in depressed conversion reaction kinetics. Consequently, this work can provide new insight for exploration and design of metal oxide/carbon composite anode materials in lithium-ion battery.

A simple hydrothermal route was designed to prepare 3D flower‐like MoS2/graphene composites (FL‐MoS2/graphene). Herein, two products, denoted C‐FL‐MoS2/graphene and N‐FL‐MoS2/graphene, were produced by facile glucose‐ and glucosamine‐mediated methods, respectively. Both composites were found to show a well‐defined morphology with a unique structure, in which the dispersed MoS2 nanoflowers are tightly anchored onto the graphene nanosheets. Moreover, the nanoflowers are constructed by a lot of wrinkled MoS2 thin nanosheets, which generates numerous open voids. In the process, glucose or glucosamine as the binder plays a similar role in regulating the growth of flower‐like MoS2 on graphene. In terms of electrochemical performance, the FL‐MoS2/graphene composite demonstrates superior lithium‐storage capabilities, including a high reversible capacity, excellent cycle stability, and good rate capability, than N‐MoS2/graphene (without the addition of any binder). Specifically, C‐FL‐MoS2/graphene shows a high reversible capacity of 980 mA h g−1 at a current of 100 mA g−1 even after 100 cycles, and a significantly improved high rate capability of 740 mA h g−1 is also retained at a current density of 1000 mA g−1. The remarkable performance of FL‐MoS2/graphene was determined to result mainly from the unique architecture comprising 3D flower‐like MoS2 particles and graphene nanosheets with superior conductivity.

One of the biggest challenges in the commercialization of tin dioxide (SnO2)-based lithium-ion battery (LIB) electrodes is the volume expansion of SnO2 during the charge–discharge process. Additionally, the aggregation of SnO2 also deteriorates the performance of anode materials. In this study, we prepared SnO2 nanoflowers (NFs) using nanocrystalline cellulose (CNC) to improve the surface area, prevent the particle aggregation, and alleviate the change in volume of LIB anodes. Moreover, CNC served not only as the template for the synthesis of the SnO2 NFs but also as a conductive material, after annealing the SnO2 NFs at 800 °C to improve their electrochemical performance. The obtained CNC–SnO2NF composite was used as an active LIB electrode material and exhibited good cycling performance and a high initial reversible capacity of 891 mA h g−1, at a current density of 100 mA g−1. The composite anode could retain 30% of its initial capacity after 500 charge–discharge cycles.
