Abstract:
Supercapacitor has been identified as one of the future energy storage devices due to its high power delivery capabilities, long cycle life, high operational temperature range and low charging/discharging time. One of the major issues with the supercapacitor based commercial devices is their poor energy density (5-10Wh/kg) as compared to those of lead acid (~30-40 Wh/kg) and Lithium-ion batteries (100-250Wh/kg), thereby limiting their applications as a substitute to the batteries. However, the supercapacitor may find supremacy in those areas where high power density is required. This would allow the burst-mode power deliveryas required in load-levelling,acceleration/brakes in vehicles and memory backup (static random access memory (SRAM)). It is, therefore desirable to improve the energy density of supercapacitors while maintaining the power density. The present invention provides a greener wet method for the synthesis of nitrogen-doped reduced graphene oxide (N-rGO) as an electrode material, exhibiting high potential window with high energy density for high performance supercapacitor employing environment friendly aqueous electrolytic system. 

 
THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
