The last ICNaB 2017 took place at Tokyo, Japan. After attending the conference last years, I
were able to obtain the valuable comments from the conference, and were able to publish mypaper to advanced sustainable system. I was fortunate that I am selected for this foundation thisyear to attend ICNaB 2018. This time the conference was held at St malo, France from 13-15
November 2018. It is one of the largest conferences in the area of sodium batteries which canbe understood by the number of invited talks and poster presentations. There were over 16
invited talks and 70 poster presentations by the prominent researchers from all over the world.
Researchers from all around the world: Germany, USA, France, Australia, China, Hongkon,
Spain, English, Japan and many more countries came to this event. Several famous companies
like Faradion, Biologic, Total, Natron Energy, etc also shared the latest technologies they areworking on.
In this academic meeting, a wide range of topics like novel analytic methods,electrolytes, cathodes, anodes, binders for sodium batteries were discussed. Although, manytalks were about cathodes and anodes yet electrolytes are getting attention of the researchers
owing to their vital role in improving battery performance and safety and vast design capability.
Among the major types of electrolytes, ionic liquids are widely investigated due to the highsafety and good performance in all the battery systems. From this conference, many findings
suggest ionic liquids as the promising candidate for the future electrolytes for batteries.
In my presentation, I reported tthat the uniform composite of NVP contained the CNFs
framework in interior its particles (NVPC@CNFs) are obtained utilizing the combination ofsonication and sol-gel method, and the electrochemical measurement is studied using a highmass loading electrode. NVPC@CNFs using Na[FSA]-[C2C1im][FSA] (C2C1im = 1-ethyl-3methylimidazolium, FSA = bis(fluorosulfonyl)amide) ionic liquid (IL) electrolyte exhibits
superior reversible charge-discharge performance, rate capability and cyclability at wide
temperature range.
I felt that this conference was very helpful in many perspectives. I presented a posterand got a lot of questions which increased my knowledge on my topic. In the poster sessions
was a really nice atmosphere for discussing the ideas in a better flow. Moreover, interactingwith other researchers provided me a glimpse of the research progress in other areas also. After
3 days of listening to the talks, meeting prominent professors and researchers, I felt more
confident and motivated to do better research in the future.
