“…Most of the reported electrochemical cycling performances of porous Si‐based anode materials prepared by combining HEMM of low‐cost Si sources and etching process were found to be stable with high reversible capacities above 1000 mAh g −1 . Several recently published review articles have largely discussed Si‐based anode materials for LIBs, but none of them focused mainly on low‐cost ball‐milling and etching routes for the synthesis of Si/C anodes for next‐generation LIBs. The following section highlights some recent advances made for the preparation of Si/C electrodes by combining simple, scalable, and low‐cost HEMM and etching processes.…”

“…[5][6][7][8] Binder has a significant impact on the electrochemical performance of the silicon-based anode featured with large volume expansion upon lithiation. [9,10] Poly (vinylidene fluoride) (PVdF), Poly (acrylic acid) (PAA), sodium alginate (SA) and sodium carboxymethyl cellulose (CMC)/styrene-butadiene-rubber (SBR) have been used as binder. [11] However, the PVdF binder fails to endure the huge external stress generated by volume expansion of the silicon because of its weak interaction with the silicon.…”

Binders play a crucial role in maintaining mechanical integrity of electrodes in lithium‐ion batteries. However, the conventional binders lack proper elasticity, and they are not suitable for high‐performance silicon anodes featuring huge volume change during cycling. Herein, a poly(siloxane imide) copolymer (PSI) has been designed, synthesized, and utilized as a binder for silicon‐based anodes. A rigidness/softness coupling mechanism is demonstrated by the PSI binder, which can accommodate volume expansion of the silicon anode upon lithiation. The electrochemical performance in terms of cyclic stability and rate capability can be effectively improved with the PSI binder as demonstrated by a silicon nanoparticle anode.

“…Studies have shown that nanostructures including 0D nanoparticles (Xu Y. et al, 2017 ), 1D nanowires/nanotubes (Ge et al, 2012 ; Kennedy et al, 2017 ), 2D nanofilms, and 3D porous structures (Yang et al, 2015 ; Xu et al, 2017 ; Chen et al, 2018 ; Mu et al, 2019 ; Fang et al, 2020b ) can significantly reduce the volume effect and shorten the diffusion distance of lithium-ion. Combining Si with other matrices is also an efficient alternative way to alleviate the volume expansion stress (Cheng et al, 2018 ; Jo et al, 2019 ; Tao et al, 2019 ). Mu et al used self-assembly and magnesiothermic reduction to prepare a pomegranate-like core-shell structured Si@C composite (Mu et al, 2019 ).…”

Silicon anodes with an extremely high theoretical specific capacity of 4,200 mAh g −1 have been considered as one of the most promising anode materials for next-generation lithium-ion batteries. However, the large volume expansion during lithiation hinders its practical application. In this work, pomegranate-like Si@SiO x composites were prepared using a simple spray drying process, during which silicon nanoparticles reacted with oxygen and generated SiO x on the surface. The thickness of the SiO x layer was tuned by adjusting the drying temperature. In the unique architecture, the SiO x which serves as the protection layer and the void space in pomegranate-like structure could alleviate the volume expansion during repeated lithium insertion/extraction. As a lithium-ion battery anode, pomegranate-like Si@SiO x composites dried at 180 • C delivered a high specific capacity of 1746.5 mAh g −1 after 300 cycles at 500 mA g −1 .
