Summary
With the increased demand for portable and clean energy, supercapacitors are emerging energy storage devices that have attracted intense attention by virtue of its high power density, short charging time and outstanding cycle stability. However, their widespread use is restricted by low energy storage density and relatively high effective series resistance. For the purpose of achieving high-performance supercapacitors, it is extremely imperative to design novel electrode materials with rational structure and composition for meeting the requirements of ideal electrodes. Currently although great progress has been achieved for carbon-based supercapacitors, which are still limited by complicated or environmentally-unfriendly synthesis procedure, unsatisfied structure and low energy density, it is still remaining a grand challenge to prepare heteroatoms-doped three-dimensional (3D) carbon network as supercapacitive electrodes with superior electrochemistry performances via a low-cost, easily scalable and eco-friendly methods. To achieve this goal, inspired by the features of intumescent flame retardants (IFRs), including rich in heteroatoms (N, P), thermos-crosslinking, tailored composition and easy carbonization to form porous char, a self-assembling and self-activation strategy is proposed to produce N/P Dual-doped 3D Carbon Network by nano-CaCO3 template-assistant carbonization of IFRs. In this project, by taking the advantages of IFRs, further combining the characters of nano-CaCO3, as hard template to construct 3D framework, also as activating agent for creating pores, the prepared 3D carbon will be expected as a promising electrode materials for supercapacitors. The project is in line with the current European research trends and societal needs, and will bring great academic value and economic benefits. In addition, the researcher and the host organization will benefit from the two-way transfer of knowledge, and open up extensive international collaborations.
