Development and Demonstration of Advanced Nanostructured Materials for Energy Storage
Applications

Dr. Srinivasan Anandan, International Advanced Research Centre for Powder Metallurgy
and New Materials (ARCI), Hyderabad, September 29
th
Dr. Srinivasan Anandan is a Senior Scientist at International Advanced Research
Centre for Powder Metallurgy and New Materials (ARCI), Hyderabad, India. He
discussed development of nanostructure materials for energy storage
applications. The first part of the talk, he highlighted the development of Li-ion
battery (LIB) materials for Electric Vehicle (EVs) applications. Indigenous
electrode materials technology and associated components that are essential for
the manufacturing of Li-ion batteries within the country are the need of the hour.
He showed the ARCI developed low-cost high energy milling process for the
synthesis of in-situ carbon modified LFP for Lithium-ion batteries. Further, he
focussed on the simple, economical scalable, and energy-efficient process
developed by ARCI for the production of LTO anode material with a performance
at par with commercial LTO. He concluded that a large-scale demonstration of ARCI’s developed LTO
process has been initiated in collaboration with Industry. He concluded by giving some information about
the Patents which are filed in India, USA, Japan and China for their invention were granted recently
information that efforts are in progress for technology transfer to a private company.

Lanthanide based Phosphors for Smart Lightings

Dr. Sivakumar Vaidyanathan, IIT Hyderabad, October 31 st

Dr. Sivakumar Vaidyanathan is currently an Associate professor in the
Department of Chemistry, IIT Hyderabad. His talk explored the Phosphor
converted white light emitting diodes (pcLEDs) which attracted a great attention
in the past few decades owing to their several advantages like eco-friendliness,
low power consumption, high efficiency, small volume and long persistence. High
performance and ultra-stable oxide based narrow band red emitting phosphors
are still a bottleneck in white LED applications. In the talk various trivalent
europium based red emitting phosphors with different crystal structure was
discussed giving special emphasis on their optical properties as well as detailed
structure -compositions-property relationship. Trivalent europium-based
monochromatic red light-emitting phosphors are a vital component to recognize
high-performance smart lighting devices; however, the concentration and thermal quenching restrict their
usageHe also investigated trivalent ion based molecular complexes aiming to obtain high performance ed
emission for solid state lighting applications.
