Akshara Nadukkandi Purayil is a first-year PhD researcher in Energy at Teesside University. Her research focuses on battery diagnostics, safety assessment and classification techniques for second-life lithium-ion batteries, with the aim of developing battery passport-oriented frameworks to enable the safe, traceable and reliable repurposing of retired electric vehicle batteries. Her work investigates battery degradation mechanisms, state-of-health estimation and future performance prediction to support informed lifecycle decision-making. As part of her doctoral research, she is investigating non-destructive battery diagnostic approaches, including ultrasonic sensing and advanced signal processing techniques, to improve battery condition assessment without invasive testing. She is particularly interested in integrating battery performance, safety and sustainability metrics to support battery passport development, circular energy systems and responsible battery lifecycle management.
Akshara presented a research poster at the ECR Net Zero Conference 2026, where she was awarded a travel bursary by the Supergen Energy Networks Hub, and has been selected to attend the Safe Battery Summer School at Lund University. She is an IEEE member, and her research aims to advance safe, data-driven and sustainable second-life battery reuse in support of the net-zero energy transition.
