Interfacial engineering of metal oxide/graphene nanoscrolls with remarkable performance for lithium ion batteries

Graphene Nanoscrolls with Confined Silicon Nanoparticles as a Durable Anode for Lithium‐Ion Batteries

“…Hence, Si would be more inclined to attach tightly with GO originated from the heterogeneous electric attraction. In addition, citric group can be converted into amorphous carbon and coated on the surface of Si after the post annealing treatment at 900 °C when GO would transform to reduced graphene oxide (rGO) …”

“…In addition, GNS ensures the continuous conductive pathways for electrons through the electrode and the flexible galleries can promote facile strain alleviation without structure collapse during battery operation . Profited from the synergistic effect of conductivity and flexibility, when applied to Si‐based negative materials of Li‐ion batteries, it would show noteworthy enhancement in electrode electrochemical performance …”

“…[22] Profited from the synergistic effect of conductivity and flexibility, when applied to Si-based negative materials of Li-ion batteries, it would show noteworthy enhancement in electrode electrochemical performance. [23,24] Here, we designed a one-dimensional flexible graphene nanoscroll wrapped silicon nanoparticles composite through directly cold quenching of mixed suspensions contained surface modified Si nanoparticles and graphene oxide (GO) and followed by a heat treatment procedure. The detailed schematic illustration of the synthesis process is shown in Figure 1.…”

“…In addition, citric group can be converted into amorphous carbon and coated on the surface of Si after the post annealing treatment at 900°C when GO would transform to reduced graphene oxide (rGO). [24] Firstly, we have investigated the morphologies of all prepared composites. The different magnified morphologies of pure GNS are shown in Figure 2a and b.…”

Growth and growth mechanism of oxide nanocrystals on electrochemically exfoliated graphene for lithium storage

“…As a novel two dimensional carbon nanomaterial, graphene has attracted wide attention due to its unique properties such as large surface area, outstanding mechanical strength, and high electrical and thermal conductivities [1,2]. As an important application, graphene has been used as an ideal substrate to support various functional materials, in order to improve their properties for a variety of applications [3][4][5]. A case in point is graphene-Mn 3 O 4 composite used as an electrode material for lithium-ion batteries (LIBs), supercapacitors and fuel cells [6][7][8].…”
