“…Comparing with bare Si/CNT or Si/Graphene anodes, Si-CNT/FSG hybrid electrode, it delivers 1100 mAh/g at 0.2 A/g current density after 100 cycles. Addition of CNT was involved to disperse the Si NPs on the surface and provide network between the graphene sheets for conductivity enhancement as well as improved Li ion intercalation for efficient charge transfer [52].…”

Free-standing graphene (FSG) paper like electrodes has paid attention to the energy storage device application in the past decade. It befits to fabricate flexible devices due to its remarkable mechanical strength and offers high electrical conductivity. In this chapter, we explore the advantages and future prospects of FSG fresh candidate in rechargeable batteries. Herein, we summarized the synthetic strategies used for FSG fabrication and its properties, followed by its application in rechargeable batteries. Extensively, this chapter deals with fabrication of FSG hybrid composite papers for battery applications to understand the overall device performance. Specifically, we discuss the benefits of FSG electrodes over conventional electrode material and its fabrication in battery system. Ultimately, we conclude with the significance of FSG paper in battery application and forthcoming advantage for recycling purposes.

A flexible self-standing Si–CNT/graphene paper was fabricated with 3-D sandwich-like structure by Cai's group [ 85 ] after combining with graphene sheets. The self-standing Si–CNT/graphene paper anode exhibited a high specific capacity of 1100 mAh g −1 even after 100 cycles at 200 mA g −1 current density with a coulombic efficiency of above 99%.…”

Lithium-ion batteries are widely used in various industries, such as portable electronic devices, mobile phones, new energy car batteries, etc., and show great potential for more demanding applications like electric vehicles. Among advanced anode materials applied to lithium-ion batteries, silicon–carbon anodes have been explored extensively due to their high capacity, good operation potential, environmental friendliness and high abundance. Silicon–carbon anodes have demonstrated great potential as an anode material for lithium-ion batteries because they have perfectly improved the problems that existed in silicon anodes, such as the particle pulverization, shedding and failures of electrochemical performance during lithiation and delithiation. However, there are still some problems, such as low first discharge efficiency, poor conductivity and poor cycling performance, which need to be improved. This paper mainly presents some methods for solving the existing problems of silicon–carbon anode materials through different perspectives.
