Sino-EU Joint Laboratory of New Energy Materials and Devices

In recent years, the development of energy storage device is conducted in two main directions: supercapacitors (SCs) and lithium-based batteries, i.e. Lithium-ion (Li-ion) and Lithium-sulphur (Li-S) batteries.  SCs demonstrate high power density, short charging time, long cycle life and reliability. Besides, SCs can potentially support more than one million charge/discharge cycles without substantial capacity drops or internal resistance increases. Although SCs provide significantly higher power in the same volume, they are not able to store the same amount of energy per unit weight and volume as Li-based batteries. Moreover, the cost per energy unit of SCs is more than 20 times higher than in case of batteries.  The main disadvantages of Li-ion and Li-S batteries include high self-discharge rate and low cycling stability.  To overcome the above mentioned problems of existing energy storage devices, the research in the Sino-EU joint lab is directed towards the development of nanostructured porous electrode materials with high pseudo-capacitance, i.e.  carbon-based electrodes modified by redox active components (conducting polymers, oxides and sulfides of transitional metals). The developed cathode materials are intended both for batteries with organic electrolyte, and for water power sources. Special attention is paid to the development of gel electrolytes with set of properties required for certain type of power source. Besides, an important direction of Sino-EU joint lab is the development of photovoltaic energy device integrated with supercapacitor for harvesting the ambient energy and self-charging without using any external supply.

The design of energy storage devices at Sino-EU joint lab is carried out in collaboration with the following organizations:

East China University of Science and Technology in Shanghai, China

Solar Energy Research Institute in Yeungnam University, South Korea

Institute of Macromolecular Compounds, Russian Academy of Sciences, St. Petersburg

Ton Duc Thang University, Vietnam
