“…Last but not least, the special 2D lamellar structure of graphene had was strong and tough which effectively alleviated the large expansion of Si NPs during the charge and discharge process. A comparison with other Si/C anode materials is shown in Figure 8, the rGO@Si NPs composite film electrode materials exhibit excellent cycling stability [32,[57][58][59][60][61][62][63][64][65]. In this regard, rGO@Si NPs-2 had the best electrochemical performance for the following reasons: first, compared with rGO@Si NPs-3, the Si NPs were evenly distributed in the rGO sheets, and no agglomeration was observed.…”

This paper describes a strategy for preparing free-standing reduced graphene oxide@Si nanoparticles (rGO@Si NPs) composite membranes. Graphene oxide (GO) was reduced and self-assembled synchronously with nanoparticles of silicon (Si NPs) on a metal surface and the composite film was subsequently used in a lithium-ion battery (LIB). This work describes several important novel aspects of the reported technology. Firstly, the composite membrane has a flexible self-supporting structure, allowing it to function as an anode material without requiring binders and current collectors. Secondly, the successful assembly of Si NPs and reduced Graphene oxide (rGO) sheets has enabled the production of the rGO@Si NPs composite film with high controllability and orderliness. Thirdly, the conductive nature of graphene has significantly decreased the resistivity while enhancing the electron transport capacity of the battery anode. Lastly, the robust and flexible structure of the graphene sheet has greatly mitigated the large volume variation in Si NPs during charging or discharging, resulting in the rGO@Si NPs composite film exhibiting excellent energy density and high-power density.

Recycling spent lithium-ion batteries (LIBs) have attracted increasing attention for their great significance in environmental protection and cyclic resources utilization. Numerous studies focus on developing technologies for the treatment of spent LIBs. Among them, the regeneration of functional materials from spent LIBs has received great attention due to its short process route and high value-added product. This paper briefly summarizes the current status of spent LIBs recycling and details the existing processes and technologies for preparing various materials from spent LIBs. In addition, the benefits of material preparation from spent LIBs, compared with metals recovery only, are analyzed from both environmental and economic aspects. Lastly, the existing challenges and suggestions for the regeneration process are proposed.

“…However, traditional commercial lithium batteries have potential safety hazards such as liquid electrolyte leakage, flammability [1,2] or fire and explosion caused by a large amount of heat-in-process use of the battery [3]. Although the above-mentioned hidden dangers can be effectively controlled through cooling schemes [3,4], solid-state rechargeable Lithium Batteries are considered to be the best candidate to fundamentally cope with the challenge, because their electrolytes do not contain any flammable liquids, and the rigidity of solid materials effectively resists the formation of lithium dendrites to avoid short circuits [5][6][7][8][9]. However, the further development of all-solid-state rechargeable lithium batteries still needs to break through the difficulties of how to reduce the interface resistance between the electrolyte and the electrode, as well as how to improve the ionic conductivity and stability of the electrolyte [10,11].…”

The application of rechargeable lithium batteries involves all aspects of our daily life, such as new energy vehicles, computers, watches and other electronic mobile devices, so it is becoming more and more important in contemporary society. However, commercial liquid rechargeable lithium batteries have safety hazards such as leakage or explosion, all-solid-state lithium rechargeable lithium batteries will become the best alternatives. But the biggest challenge we face at present is the large solid-solid interface contact resistance between the solid electrolyte and the electrode as well as the low ionic conductivity of the solid electrolyte. Due to the large relative molecular mass, polymers usually exhibit solid or gel state with good mechanical strength. The intermolecules are connected by covalent bonds, so that the chemical and physical stability, corrosion resistance, high temperature resistance and fire resistance are good. Many researchers have found that polymers play an important role in improving the performance of all-solid-state lithium rechargeable batteries. This review mainly describes the application of polymers in the fields of electrodes, electrolytes, electrolyte-electrode contact interfaces, and electrode binders in all-solid-state lithium rechargeable batteries, and how to improve battery performance. This review mainly introduces the recent applications of polymers in solid-state lithium battery electrodes, electrolytes, electrode binders, etc., and describes the performance of emerging porous polymer materials and materials based on traditional polymers in solid-state lithium batteries. The comparative analysis shows the application advantages and disadvantages of the emerging porous polymer materials in this field which provides valuable reference information for further development.
