Battery

​

Li ion battery has had a huge impact in technology today and it will have much higher impact in decades. As the battery life for most of these around 3-5 years depending on the usage, as we go more towards electric vehicle, there will be more batteries and there will be greater push towards recycling and reuse the battery components. We have over the years worked on some aspects of battery, focusing particularly on recycling Li ion systems. Creation of new designs methods of extraction of anode and cathode materials. Extraction of graphene from spent graphite and plasma based process to deposit recycled graphite for wide variety of applications.  Our ongoing work captures all these aspects of recycling of Li ion battery and we are constantly thinking about new formats for recycle, reuse and new products using recycled  Li ion battery.

Supercapacitors

​

Electric double layer capacitors (and pseudo capacitors) form the class of supercapacitors, are also electrochemical energy storage devices but with different characteristics than traditional battery. In these systems energy density of supercapacitors are much smaller than that of battery, but the power density may be orders of magnitude higher because of their fast charge. Carbon materials are typically used as electrodes in electric double layer capacitors whereas oxides and other electrode materials give pseudo-capacitance. Our research group currently working on three dimensional and 2D nanostructured electrode materials are being developed for the next generation of supercapacitor electrodes.
