“…The commercially dominating anode materials are graphite and lithium titanate [ 13 ]. Battery experts also anticipate the transition to alloyed silicon and silicon oxide, SiO x , because of their higher specific capacities compared to carbon-based anodes [ 14 , 15 , 16 , 17 , 18 ]. Although the development of electrode materials for LIBs is actively progressing [ 19 , 20 , 21 , 22 , 23 ], research in electrolyte has also gained interest from both academic and industry practitioners [ 24 , 25 , 26 , 27 ].…”

Searching for a suitable electrolyte in a lithium-ion battery is a challenging task. The electrolyte must not only be chemically and mechanically stable, but also be able to transport lithium ions efficiently. Ionic liquid incorporated into a metal–organic framework (IL@MOF) has currently emerged as an interesting class of hybrid material that could offer excellent electrochemical properties. However, the understanding of the mechanism and factors that govern its fast ionic conduction is crucial as well. In this review, the characteristics and potential use of IL@MOF as an electrolyte in a lithium-ion battery are highlighted. The importance of computational methods is emphasized as a comprehensive tool to investigate the atomistic behavior of IL@MOF and its interaction in electrochemical environments.

“…To address the issues associated with Si, especially volume expansion, massive efforts have been made, including: avoiding materials pulverization via the design of silicon nanostructures, ( An et al, 2020 ; Qi et al, 2020 ; Sun et al, 2022a ; Sun et al, 2022b ; Li et al, 2022 ) improving cycling stability through SiO/SiO x -based anode materials, ( Wang et al, 2020a ; Tian et al, 2022 ) and increasing electronic/ionic conductivities through utilizing advanced electrolyte additives and novel binders. ( Huang et al, 2019 ; Zhao et al, 2021 ; Zhou et al, 2021 ; Zhu et al, 2021 ) The 3D porous Si-based materials have enough internal voids to accommodate volume expansion due to the existence of their large pores, so that their structures can maintain their integrity during the processes of lithiation/delithiation, avoiding pulverization of silicon-based materials.…”

Silicon (Si)-based anode materials have been the promising candidates to replace commercial graphite, however, there are challenges in the practical applications of Si-based anode materials, including large volume expansion during Li+ insertion/deinsertion and low intrinsic conductivity. To address these problems existed for applications, nanostructured silicon materials, especially Si-based materials with three-dimensional (3D) porous structures have received extensive attention due to their unique advantages in accommodating volume expansion, transportation of lithium-ions, and convenient processing. In this review, we mainly summarize different synthesis methods of porous Si-based materials, including template-etching methods and self-assembly methods. Analysis of the strengths and shortages of the different methods is also provided. The morphology evolution and electrochemical effects of the porous structures on Si-based anodes of different methods are highlighted.

“…However, two major issues impede the commercialization of silicon anodes. Specifically, the dramatic volume change (>300%) during Li alloying and dealloying processes ( Jin et al, 2017 ) and poor electronic conductivity ( Liang et al, 2014 ; Sun et al, 2022 ) of silicon result in drastic capacity decay ( Xu et al, 2019 ) and inferior rate capabilities, respectively ( Ozanam and Rosso, 2016 ). Therefore, two main strategies have been proposed to improve the electrochemical performance of the Si anodes.…”

Silicon is considered as the most promising candidate for anodes of next generation lithium-ion batteries owing to its natural abundance and low Li-uptake potential. Building a macroporous structure would alleviate the volume variation and particle fracture of silicon anodes during cycling. However, the common approaches to fabricate macroporous silicon are complex, costly, and high energy-consuming. Herein, bamboo leaves are used as a sustainable and abundant resource to produce macroporous silicon via a scalable magnesiothermic reduction method. The obtained silicon inherits the natural interconnected network from the BLs and the mesopores from the BL-derived silica are engineered into macropores by selective etching after magnesiothermic reduction. These unique structural advantages lead to superior electrochemical performance with efficient electron/ion transport and cycling stability. The macroporous Si@C composite anodes deliver a high capacity of 1,247.7 mAh g−1 after 500 cycles at a current density of 1.0 A g−1 with a remarkable capacity retention of 98.8% and average Coulombic efficiency as high as 99.52% for the same cycle period. Furthermore, the rate capabilities of the Si@C composites are enhanced by conformal carbon coating, which enables the anode to deliver a capacity of 538.2 mAh g−1 at a high current density of 4.0 A g−1 after 1,000 deep cycles. Morphology characterization verifies the structural integrity of the macroporous Si@C composite anodes. This work demonstrated herein provides a simple, economical, and scalable route for the industrial production of macroporous Si anode materials utilizing BLs as a sustainable source for high-performance LIBs.
