Research

Rutooj’s research is mainly focused on understanding and improving lithium ion batteries through mathematical modeling and experiments. He modeled diffusion induced stresses to understand the mechanical degradation of anode material in lithium ion battery.  He is also doing experimental work and trying-out novel anode materials for better battery life.
