Electrochemical Carbon Nanotube Synthesis for Application in Lithium-Ion Batteries Imperial College London in United Kingdom

This PhD project at Imperial College London focuses on the electrochemical synthesis of multi-walled carbon nanotubes (MWCNTs) from CO2 and their application in lithium-ion batteries. The research aims to evaluate the benefits of incorporating MWCNTs, produced in-house via molten carbonate electrolysis, into battery anodes and cathodes. This innovative approach leverages the expertise of Dr. Anna Hankin in carbon nanotube synthesis and Prof. M. Titirici in battery chemistry development, targeting more sustainable and cost-effective energy storage solutions that contribute to the net zero transition.

Conventional lithium-ion batteries use graphite as the anode and carbon black as a cathode additive. Carbon nanotubes, known for enhancing material properties, offer potential as alternative anode materials and cathode additives. The inclusion of CNTs can reduce reliance on carbon black, decrease battery weight, increase specific capacity, and eliminate chemical binders. However, traditional CNT synthesis via chemical vapour deposition is costly and emits CO2. The project addresses this by developing a scalable, energy-efficient process for CO2 capture and conversion to CNTs, which is significantly less energy intensive than conventional methods.

The research objectives include: (a) developing a deep understanding of carbon electrodeposition kinetics to achieve high selectivity in nanostructure synthesis; (b) evaluating the impact of different carbon nanostructures on battery performance, including trials in Na- and K-ion batteries; (c) determining optimal nanostructures and synthesis conditions; and (d) conducting a techno-economic evaluation of CO2-derived versus CH4-derived CNTs in battery electrodes. The project is based in the Hankin lab, which has already demonstrated successful CNT synthesis and reactor design, and will be extended to battery testing in the Titirici lab.

Applicants will conduct independent research, collaborate with a team, support ongoing projects, and maintain safe laboratory practices. The position is fully funded for 42 months and offers opportunities for intellectual property generation and collaboration with industrial partners. Candidates should have a first-class bachelor’s or distinction at master’s degree in chemical engineering, chemistry, physics, materials science, electrical engineering, or mechanical engineering, and demonstrate excellent communication skills. English language requirements must be met as per Imperial College London guidelines.

Applications should be submitted via the College’s online application system. Prospective candidates are encouraged to contact Dr. Anna Hankin ([email protected]) to discuss the opportunity before applying, citing ‘CNT PHD’ in the email subject. The application deadline is March 25, 2026.
