Towards practical lithium metal batteries with composite scaffolded lithium metal: an overview
The successful employment of lithium metal substituting for the conventional graphite anode can promote a significant leap in the cell energy density for its ultrahigh theoretical specific capacity, the lowest electrochemical voltage, and low density. However, the notorious lithium dendrite growth, low Coulombic efficiency, and massive volume expansion seriously fetter its practical usage. Adopting three-dimensional (3D) structured scaffolds with large specific surface area and porous structure to stabilize lithium metal inside has been regarded as one of the most effective strategies to enhance the electrochemical performance of Li metal and eliminate the safe concerns. Herein, the current progress of composite scaffolded Li metal anodes is reviewed according to the host types, lithiophilic sites, structure, and the preparation technology to stimulate the development of Li metal batteries. Furthermore, to boost the commercialization of the composite scaffolded Li metal anode, the perspectives and critical challenges of the scaffolded Li metal anodes toward practical usage have also been prospected.
Graphical abstract
3D scaffolds joint with lithiophilic sites enable highly stable scaffolded Li metal and high-performance practical Li metal batteries.
期刊介绍：
Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field.
The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest.
Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials.
Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
