PhD Position Design-led synthesis of nanostructured energy storage materials

University of Limerick

Background
Sustainable and application-tailored long-duration energy storage technologies will be critical for the mass
deployment of renewable energy sources. Lithium ion batteries remain the powerhouse of current energy
storage but are not suitable for high energy density needed for, e.g., electric vehicles. Lithium metal batteries
naturally provide superior energy density, far beyond current Li-ion batteries, but practical applications are
hindered mainly by electrical shorting due to dendrite formation and build-up of ‘dead Li’ during cycling. At
the Bernal Institute at UL we are combining modelling and experimental efforts to develop more efficient
nanomaterials for metal anode batteries. These hosted anodes will allow safer, higher energy density
batteries to be produced. The combination of modelling with experimental approaches within the project
will provide a powerful atomic-level understanding of the complex metal stripping/plating processes, paving
the way for rational design of better performing batteries.
Project Objectives
 Synthesise new host materials for high performance metal anodes
 Diagnose failure mechanisms from experimental characterisation and modelling
 Pre-screen material for metallophilicity and enable a ‘guided by modelling’ approach for material design
 Examine Li ion transport using electrical measurements and diffusion models
Methodology
The project will apply a multidisciplinary focus to a complex material development problem.
The PhD. researcher will develop a well-rounded skillset including:
 Wet chemical approaches for hosted anodes on lightweight support substrates including commercial
carbon papers. Material design will aim to minimise adding excess mass into the final cell.
 Electrochemical testing including galvanostatic charge/discharge testing, with cells examined in half and
full cell geometries. Extensive ex-situ analysis will be used to inform synthesis.
 Characterization of active materials using state of the art equipment including TEM, SEM, XRD and
measurements such as Raman/FTIR. In-situ TEM will be used to probe Li plating directly.
 Density functional theory (DFT) and molecular dynamics (MD) simulations performed on highlyparallelised supercomputing platforms.
