Discovery of inorganic lithium solid electrolytes for all-solid-state batteries
- Supervisors: Prof Matthew Rosseinsky Dr Ruiyong Chen Prof Laurence Hardwick
All-solid-state Li metal batteries promise safer electrochemical energy storage with higher energy densities. Discovery of new high-performance Li solid electrolytes remains the core interest to advance the technological development. This project involves the experimental design and compositional exploration of a new class of inorganic materials, detailed characterisation of the materials and full-cell level optimisation of the electrochemical properties and understanding of relevant new mechanisms and chemistries.
The project will combine synthetic solid-state chemistry, advanced structural analysis and measurement of physical and electrochemical properties of new lithium solid electrolytes, enabling the successful candidate to develop a diverse experimental skillset in materials chemistry and battery chemistry. The focus will be on the discovery of new materials and structures with enhanced performance, accelerated by working with computational design experts. Owing to the multi-faceted nature of this dynamic project, the student will work closely with computer scientists, inorganic (electro)chemists, physicists, engineers, and material scientists, as part of the EPSRC Programme Grant “Digital navigation of chemical space for function”, to discover new solid electrolytes for all-solid-state Li metal batteries.
Qualifications: Applications are welcomed from students with a 2:1 or higher master’s degree or equivalent in Chemistry, Physics, Engineering, or Materials Science.
This position will remain open until a suitable candidate has been found.
The funding for this position may be a University of Liverpool School Funded Studentship (SFS) or an EPSRC Doctoral Training Partnership (DTP) studentship. The eligibility details are below.
Applications from candidates meeting the eligibility requirements of the EPSRC are welcome – please refer to the EPSRC website http://www.epsrc.ac.uk/skills/students/help/eligibility/.
If this studentship is funded by the EPSRC DTP scheme and is offered for 3.5 years in total. It provides full tuition fees and a stipend of approx. £17,668 (this is the rate from 01/10/2022) full time tax free per year for living costs. The stipend costs quoted are for students starting from 1st October 2022 and will rise slightly each year with inflation.
