Additional Desirable Experience: Background in inks chemistry, including rheology, binder solvent interactions and substrate compatibility. Experience with advanced materials characterisation techniques such as SEM and Raman. Experience working with gloveboxes or moisture‑sensitive materials A track record of translating research into commercially viable products or solutions and delivering projects that meet commercial and regulatory requirements. What you will do Key responsibilities include: Conducting R&D into next‑generation energy storage materials and devices using Gii electrodes, prioritising commercially viable solutions. Apply advanced materials chemistry principles to develop next-generation printed primary and secondary batteries prioritising the innovation of non-lithium rechargeable systems and their associated active materials. Analyse battery mechanisms, reaction kinetics and material interactions to understand performance, stability, and degradation pathways. Design and execute electrochemical tests using potentiostats and battery cyclers, including impedance and voltammetric methods. Prepare high‑precision solutions and maintain strong GLP/GMP laboratory standards. Perform materials characterisation using analytical techniques such as SEM and Raman. Independently plan and execute experiments (including DOEs) in line with project timelines, budgets, SOPs and safety requirements. Take ownership of technical project delivery, identifying risks and driving innovative solutions to complex challenges. Analyse complex electrochemical and materials data and present insights clearly to technical and non‑technical audiences. Write technical reports, contribute to presentations, and support the creation and maintenance of SOPs, SWPs, COSHH and risk assessments.
