Moving towards a more electrified world presents considerable energy storage challenges. Amongst these, the development of low cost, durable, high energy density, safe batteries is paramount for delivery of an all-electric vehicle market. A major theme of our research is to develop novel, facile routes to functional materials using our expertise in solid state and wet chemical synthetic methods to provide new battery electrodes and electrolytes across a range of battery chemistries. At the Energy Storage Research Centre (ESRC) at Sheffield, we apply a comprehensive range of lab- and synchrotron-based techniques to fully interrogate these materials to elucidate their structure and morphology, investigate their physical and dynamic properties and evaluate their electrochemical performance. Our current research in this area includes:
High nickel-content electrodes for Li-ion batteries
The benefits of moving to high nickel-content electrodes include potentially higher energy densities and reducing the cobalt content, which addresses the ethical implications and cost associated with this metal. Our group work on the synthesis of micron and nanosized NMC variants. Together with our collaborators in the Faraday Institution Degradation Fast Start project, we investigate the degradation mechanisms in these materials through a holistic approach and design methodologies to mitigate those deleterious effects.
Next generation cathode materials for Li-ion batteries
We are interested in new electrode architectures that enhance long-term performance and durability. Our group has experience in core-shell structures, faceted particles and composite materials. We also investigate coating strategies for electrode particles.
