The present invention provides a novel composite electrode and its method of preparation using synergy of PEDOT:PSS and SWCNT (Purity > 90%) with LiFePO4 active material. The prepared electrode has improved capacity as well as it works at very high current rate which can fulfil the requirement of electric vehicles. The composite electrode cell also shows low polarization and high Li-ion diffusion.The composition/process of the proposed electrode has very high improvement in the electrochemical performance of LiFePO4 cathode material as compared to conventional electrode. The electrode consists of water soluble polymer which is a replacement of a harmful chemical NMP used as solvent in conventional electrodes preparation.

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.
