The EPSRC Centre for Doctoral Training (CDT) in Renewable Energy Northeast Universities (ReNU)is a collaborative doctoral training programme run by the Universities of Northumbria, Newcastle and Durham. In addition to undertaking an individual scientific research project at one of the three partner Universities, doctoral candidates will engage with added value training opportunities, for example in business, innovation and internationalisation through a 4-year training programme that has been designed to maximise the benefits of a cohort approach to doctoral training. The start date is 1st March 2023.
Silicon-based anodes for lithium ion batteries (LIBs) offer considerably higher energy density than graphite ones and better stability than lithium ones, but have a key problem in which silicon is susceptible to swelling upon lithiation, thus causing surface cracking and rapidly decreased energy storage performance.
This project aims to improve the efficiency of batteries using a cost-effective manufacturing approach to fabricate novel graphene/silicon composite anode with high-efficiency nanostructured heterogeneous designs. The performance and stability of LIB anodes can be boosted using graphite-silicon composites, without apparent swelling issues. To take advantage of silicon’s high storage capacity for lithium, there is a requirement to improve stability, which is achievable using new material design and/or new production techniques. Different anode process techniques and their impact on anode structure and performance will be determined, including methods of graphene coated silicon structure in order to address stability issues and avoid direct contact of the silicon surface with the electrolyte, which may cause a reduction of silicon contact with the current collector. The key research topic will be focused on the study of their degradation mechanisms and relationship between performance and microstructures. Electrochemical performance of the anode materials and their structural characterisations will be performed to determine the charge/discharge mechanisms during cycling.
Key novelties: Create invented multifunctional surfaces with designed morphology and the crystal growth mechanisms; Design the anode’s structures to reduce ions diffusion and improve charge/discharge rate, and control homogenously diffusive surface interactions; Provide highly active sites and large surface areas to increase Li-ions’ storage, specific capacity, and high diffusion of the Li-ions; Construct electrodes using 2D nanostructures to facilitate the transfer of electrons, active sites formations, and achieve outstandingly electrochemical performance.
Applicants for this position should have a solid foundation and passion for carbon-based nanomaterials such as graphene and carbon nanotubes, and an excellent knowledge of their applications within energy storage devices. Experience of preparing, developing and characterising dispersions of such materials would be highly desirable for this role.
Currently, relatively large amount of intellectual properties exist within the relatively narrow fields of lithium-silicon batteries, and so a good knowledge of relevant IPs within this field would also be beneficial.
The project is supported by an industry partner: Applied Graphene Materials UK Ltd.
