“…27 Graphene was considered as a rapidly rising star material and attracted a great deal of attention owing to its excellent mechanical, electrical, thermal, and optical properties. [28][29][30][31] A key topic in the research and applications of graphene is the reduction of graphene oxide (GO). Nowadays, many different synthesis strategies have been developed to produce graphene through the reduction of GO.…”

Multifunctional integration is an inherent characteristic for biological materials with multiscale structures. Learning from nature is an effective approach for scientists and engineers to construct multifunctional materials. In nature, mollusks (abalone), mussels, and the lotus have evolved different and optimized solutions to survive. Here, bio-inspired multifunctional graphene composite paper was fabricated in situ through the fusion of the different biological solutions from nacre (brick-and-mortar structure), mussel adhesive protein (adhesive property and reducing character), and the lotus leaf (self-cleaning effect). Owing to the special properties (self-polymerization, reduction, and adhesion), dopamine could be simultaneously used as a reducing agent for graphene oxide and as an adhesive, similar to the mortar in nacre, to crosslink the adjacent graphene. The resultant nacre-like graphene paper exhibited stable superhydrophobicity, self-cleaning, anticorrosion, and remarkable mechanical properties underwater.

“…As a kind of carbon materials, graphene has attracted attention in increasing the electrochemical performance of LiFePO 4 because of its large specific surface area (theoretical value of 2630 m 2 g −1 ), flexible structure, superior chemical/thermal stability, and most importantly excellent electric conductivity [89][90][91][92][93][94]. With the help of graphene, the electrons could be transferred easily between the LiFePO 4 particles and current collectors, reducing the internal resistance and enhancing the power density of the batteries [95,96].…”

Abstract:Olivine lithium iron phosphate (LiFePO4) is considered as a promising cathode material for high power-density lithium ion battery due to its high capacity, long cycle life, environmental friendly, low cost, and safety consideration. The theoretical capacity of LiFePO4 based on one electron reaction is 170 mAh g −1 at the stable voltage plateau of 3.5 V vs. Li/Li + . However, the instinct drawbacks of olivine structure induce a poor rate performance, resulting from the low lithium ion diffusion rate and low electronic conductivity.In this review, we summarize the methods for enhancing the rate performance of LiFePO4 cathode materials, including carbon coating, elements doping, preparation of nanosized materials, porous materials and composites, etc. Meanwhile, the advantages and disadvantages of above methods are also discussed.

“…The CDM is capable of dealing with systems containing a large number of atoms and the effects caused by the structure orientations. It is well-known that graphene is an extraordinary material due to its fascinating properties and possible applications [18]. Graphene also provides state-of-the-art classes of material such as carbon nanotubes (CNTs), bulky balls, graphene nanoribbons (GNRs) and GNWs (see Fig.1).…”

The van der Waals interactions between two parallel graphitic nanowiggles (GNWs) are calculated using the coupled dipole method (CDM). The CDM is an efficient and accurate approach to determine such interactions explicitly by taking into account the discrete atomic structure and many-body effect. Our findings show that the van der Waals forces vary from attraction to repulsion as nanoribbons move along their lengths with respect to each other. This feature leads to a number of stable and unstable positions of the system during the movement process. These positions can be tuned by changing the length of GNW. Moreover, the influence of the thermal effect on the van der Waals interactions is also extensively investigated. This work would give good direction for both future theoretical and experimental studies.
