Energy Storage Technology for the Future

 

Research Overview

Advanced functional nanomaterial design for use in electrochemical energy storage devices: Designing ultra-porous carbon and metal-organic materials (e.g., graphene/metal-organic-framework composites), Producing highly electrical conductive, ionic conductive materials, Controlling the battery/supercapacitor metal oxide materials, Fabricating high specific energy and power batteries/supercapacitors from functional nanocomposites (e.g., graphene/metal oxide, manganese oxide, graphene aerogel, Li-S core shell, and conducting polymers).

Energy Storage Technology

Electrical energy plays a dominant role to the citizens’ well-being and the social prosperity of the developed economies. Electrical energy storage technology perspectives have attracted the research interest of the scientific community during the last two decades due to its determining impact upon transportation modes (electric-based mobility: electric vehicles–EVs, hybrid cars, and electric drive-trains), energy-consumed household tasks (Smart House and Smart Grid concepts), working environment, and portable electronic devices.

Our research team at VISTEC has been investigating the feasibility and capabilities of energy storage systems including electrochemical storages such as batteries and supercapacitors. This technology is proven more efficient compared to other candidate technologies, because it is more suitable in terms of the scalability, efficiency, lifetime, discharge time, and weight and/or mobility of the system. In particular, lithium sulfur batteries are proven the most successful portable electricity storage devices.

Li-S Batteries

The demand for rechargeable batteries in portable electronics and electric vehicles has stimulated extensive studies on various lithium-based electrode materials. Sulfur is nontoxic and earth-abundant, it hosts two lithium ions, and exhibits a theoretical capacity of 1675 mA h g−1, almost 10 times higher than that of LiCoO2. In terms of the gravimetric energy density, at 2.1 V versus Li/Li+, it is still 5 times higher than that of LiCoO2.

Supercapacitors

As supercapacitors are electrochemical energy storage devices, the way that supercapacitors store energy is based, in principal, on two types of capacitive behavior: the electrical double layer (EDL) capacitance from the pure electrostatic charge accumulation at the electrode interface, and the pseudo-capacitance developed from fast and reversible surface redox processes at characteristic potentials.
