  • CSIR mentioned the research interests of N Kalaiselvi on its official website. These interests include lithium batteries, supercapacitors, waste-to-wealth driven electrodes, electrolytes for energy storage, and electrocatalytic applications. According to Dr T Prem Kumar, one of her former colleagues, electric mobility was very close to N Kalaiselvi’s heart. In a media interview, Dr T Prem Kumar said that she had a great interest in those things that needed improved batteries. He said,
    Electric mobility… that is something very close to her heart, and that needs improved batteries. Also, wider utilisation of renewable energies like wind or solar.”
  • A fast-track construction program of a low-cost toilet unit while using the technology of CSIR-CECRI was initiated by her in Chennai in January 2022.

  • According to the official website of CSIR, she worked as a guide to 8 research scholars for their PhD. degrees and 6 researchers were pursuing their PhD till August 2022. Till 2022, she has worked on over 125 research papers and credited six patents to her name.
  • Once, in a media conversation, she disclosed that she received her school education in Tamil medium school, which helped her to understand science subjects in her mother tongue. She added that learning subjects in her mother tongue helped her a lot in grasping the science concepts more easily in her college. She remembered,
    In fact, it has helped me in quick grasping of science concepts and I built on that foundation when I joined college.”
