Despite being one of the most promising materials in anode materials, molybdenum sulfide (MoS2) encounters certain obstacles, such as inadequate cycle stability, low conductivity, and unsatisfactory charge‐discharge (CD) rate performance. In this study, a novel approach is employed to address the drawbacks of MoS2. Carbon polymer dots (CPDs) are incorporated to prepare three‐dimensional (3D) nanoflower‐like...
The state‐of‐the‐art development progress of the fabrication, design, modification, and applications of TiO2‐B‐based hierarchical nanostructures with a well‐controlled size and morphology in lithium‐ion battery (LIB) applications has been summarized and discussed. Based on studying on lithiation/delithiation on mechanisms of a typical metal oxide nanomaterials, along with doping with foreign atoms...
Building a rechargeable battery with high capacity, high energy density, and long lifetime contributes to the development of novel energy storage devices in the future. Although carbon materials are very attractive anode materials for lithium‐ion batteries (LIBs), they present several deficiencies when used in sodium‐ion batteries (SIBs). The choice of an appropriate structural design and heteroatom...
In article number 1902201, Ming Zhang and co‐workers report a new anode of TiO2‐carbon fiber composites for Li/Na‐ion batteries. The porous properties arising from ultrasmall and uniformly distributed TiO2 nanoparticles and capacitance effects of S‐doping make the composites ideal for high specific capacity and good stability anodes, especially in Na‐ion batteries.
SnO2‐based lithium‐ion batteries have low cost and high energy density, but their capacity fades rapidly during lithiation/delithiation due to phase aggregation and cracking. These problems can be mitigated by using highly conducting black SnO2−x, which homogenizes the redox reactions and stabilizes fine, fracture‐resistant Sn precipitates in the Li2O matrix. Such fine Sn precipitates and their ample...
