Abstract:

Energy storage plays an important role in the modern world. One of the main trends that drive energy storage development is the rise of electrical devices (e.g. smart phones, smart watches, e-books, smart keys), internet of Things (IoT) in our daily life. Despite their great success, lithium ion batteries (LIBs) still need improvements in energy density, fast charge capabilities, cyclic durability and cost. LIBs are not fully safe in certain conditions and the commercial failure of Samsung Galaxy Note 7 in 2016 is an incontestable example. Extensive efforts have been devoted to either improve LiBs by replacing the commercial cathode (e.g. LiCoO2) or by designing new batteries without Lithium (Li) (e.g. Al, Mg, Na, Zn batteries) responding to the concern about the limited Li resource. New devices are required to be more sustainable and greener with respect to our environment. In this context, vanadium oxides, graphene and their related compounds are nowadays the most appealing materials for applications in energy harvesting.

VANABATSUP project intends to synthesize, test and develop advanced batteries or super capacitors based on doped vanadium oxide/graphene composites as sustainable, eco-friendly and ultra-performance storage resources. Despite their good promises, the commercialization of hybrids vanadium oxides-graphene based composites is hampered by various obstacles including fastidious synthesis methods, including the current use of graphene oxide which can lose its efficiency due to a tendency to aggregate. Recently, the project leader has demonstrated not only the possibility to synthesis few layers of graphene by physical vapor deposition (PVD) method, but also shown their applicability as electrochemical devices. A recent review underlined that those graphene layers have not yet been tested for energy storage application. Therefore, VANABATSUP intends to fill this gap and aims to propose alternative cathodes for energy storage application.
