“…With the late development, more and more inorganic materials have been used as cathode material for LIBs, while compared to the anode materials, there are only a few progresses with cathode materials for flexible LIBs. Until now, graphene paper , graphene/LiFePO 4 nanocomposite , graphene/V 2 O 5 paper , MoO 3 /graphene film , FeF 3 /graphene paper , and graphene/TiO 2 nanoparticles have been reported as cathode materials in flexible LIBs. Ding et al prepared 3D graphene/LiFePO 4 nanostructures by solvent evaporation method.…”

SUMMARYSustainable development of renewable energy sources is one of the most important themes that humanity faces in this century. Wide use of renewable energy sources will require a drastically increased ability to store electrical energy. Electrochemical energy storage devices are expected to play a key role. With the increased demand in flexible energy resource for wearable electronic devices, great efforts have been devoted to developing high-quality flexible electrodes for advanced energy storage and conversion systems. Because of its high specific surface area, good chemical stability, high mechanical flexibility, and outstanding electrical properties, graphene, a special allotrope of carbon with two-dimensional mono-layered network of sp 2 hybridized carbon, have been showing great potential in next-generation energy conversion and storage devices. This review presents the latest advances on the flexible graphene-based materials for the most vigorous electrochemical energy storage devices, that is, supercapacitors and lithium-ion batteries.

“…Many studies on flexible batteries have focused on secondary lithium ion batteries (LIB) that require conformable active electrode materials, current collectors, and solid electrolytes. Typical active materials used for flexible electrodes include carbon nanotubes (CNTs) [1e4], carbon nanofibers [5], graphene [6,7], metallic oxidebased nanowires [8], and slurry-type mixtures [9,10]. In most of the studies above, the electrodes were prepared through a simple method in which nano-sized active materials are mixed with a binder polymer and a conducting additive in order to make a slurry mixture, and this mixture is then coated on a metallic current collector.…”

“…The single atomic layer thickness results in an ultrahigh surface area of 2600 m 2 g −1 theoretically (although this is reduced upon electrode formation). This, in combination with its chemical inertness and low cost of exfoliated variants, makes graphene an ideal supercapacitor electrode material . In addition, a single layer, high quality graphene sheet produced by chemical vapor deposition (CVD) also exhibits high transparency with 2.4% absorption over the visible range, and high mechanical flexibility, making it a potential alternative indium doped tin oxide (ITO) .…”

Energy scavenging has become a fundamental part of ubiquitous sensor networks. Of all the scavenging technologies, solar has the highest power density available. However, the energy source is erratic. Integrating energy conversion and storage devices is a viable route to obtain self-powered electronic systems which have long-term maintenance-free operation. In this work, we demonstrate an integrated-power-sheet, consisting of a string of series connected organic photovoltaic cells (OPCs) and graphene supercapacitors on a single substrate, using graphene as a common platform. This results in lighter and more flexible power packs. Graphene is used in different forms and qualities for different functions. Chemical vapor deposition grown high quality graphene is used as a transparent conductor, while solution exfoliated graphene pastes are used as supercapacitor electrodes. Solution-based coating techniques are used to deposit the separate components onto a single substrate, making the process compatible with roll-to-roll manufacture. Eight series connected OPCs based on poly(3-hexylthiophene)(P3HT):phenyl-C61-butyric acid methyl ester (PC60 BM) bulk-heterojunction cells with aluminum electrodes, resulting in a ≈5 V open-circuit voltage, provide the energy harvesting capability. Supercapacitors based on graphene ink with ≈2.5 mF cm(-2) capacitance provide the energy storage capability. The integrated-power-sheet with photovoltaic (PV) energy harvesting and storage functions had a mass of 0.35 g plus the substrate.
