In recent years, metal compound-based heterojunctions have received increasing attention from researchers as a candidate anode for lithium/sodium-ion batteries, because heterojunction anodes possess unique interfaces, robust architectures, and synergistic effects, thus promoting Li/Na ions storage and accelerating ions/electrons transport.
In recent years, heterojunctions have received increasing attention from researchers as an emerging material, because the constructed heterostructures can significantly improve the rate capability and cycling stability of the materials.
The defective TiO 2 @Co@NC heterojunction anode using self-assembled nanotubes as a scaffold exhibits enhanced lithium-ion storage performances. Besides, Ni et al. 15a prepared ordered S−Fe 2 O 3 nanotubes by combining electrochemical anodization of Fe foil and subsequent sulfurization process.
Rechargeable batteries are key in the field of electrochemical energy storage, and the development of advanced electrode materials is essential to meet the increasing demand of electrochemical energy storage devices with higher density of energy and power. Anode materials are the key components of batteries.
Those heterogeneous catalysts facilitate the adsorption of polysulfides, enhance their conversion to lower-order species, promote efficient redox reactions, and mitigate the notorious shuttle effect, leading to improved performance and enhanced cycling stability of Li-S batteries.
In addition, building blocks undergo phase variation during the charging and discharging process, which may damage the heterostructures, thus severely limiting the practical application of heterojunction in energy storage.
