Abstract:
Lithium-ion batteries (LIBs) are the most powerful way of energy conversion and storage. Thin film batteries are the next generation of Li-ion battery technology with the thickness of tens µm and aimed to power a diverse range of microdevices. In order to increase the storage possibility of such batteries, new high capacity electrode materials should be developed. Silicon(Si)-based materials are the most promising anodes due to the highest theoretical capacity and a low potential. However, the current drawbacks of Si such as significant material degradation, low conductivity, and unstable solid electrolyte interphase layer impede its practical application and commercialization. In this doctoral thesis, the research has been performed in two main directions in order to improve the performance of current microbatteries.

The first direction is devoted to an investigation of novel monocrystalline silicon carbide thin film (3C-SiC) with a cubic lattice as an anode for LIBs. The advanced method of “single” particle measurement for studying the electrochemical properties of an individual microparticle provided the real data which allowed suggesting the mechanisms of lithiation/delithiation in 3C-SiC film. The use of the characterization techniques confirmed the high mechanical stability of the 3C-SiC crystal lattice after cycling. The obtained cutting-edge results demonstrated that 3C-SiC thin film exhibits the near-surface activity towards Li ions occurring through intercalation/deintercalation mechanism.

The second direction is aimed at the design of the three-dimensional (3D) amorphous Si (a-Si) thin film anode. The improvement of a-Si thin film anode was achieved through studying the effects of substrate surface condition, dopants incorporation, electrolyte additive and use of graphene (GF) underlayer. The designed 3D pure a-Si and a-Si/GF thin film anodes exhibited high electrochemical performance for several hundred cycles.

Presentation 1.      

Title: Energy Storage and Renewable Energy Deployment: Empirical Evidence from OECD counties (1 hour including Q&A)

Abstract: Renewable energy can reduce greenhouse gas emissions by providing renewable electricity, heating, cooling and transportation. The main disadvantage of renewable energy supply is that once it reached a high share in electricity generation, the intermittency caused by renewable energy sources makes balancing of the energy system challenging. This study answers the question “What is the impact of renewable energy on public investment in R&D of energy storage technologies?” Empirical literature studying investments in renewable energy technologies is abundant, however empirical literature studying investments in energy storage technologies is highly limited. Using annual panel data from 28 OECD countries over the period 1990-2014 this paper provides an empirical evidence on the role of renewable energy deployment on public investments in energy storage technologies. The results of fixed effects estimation provide an empirical evidence that governments from countries with greater share of renewable energy invest more in energy storage technologies. Drawing from the empirical results, this paper provides policy recommendations on the need in investments in energy storage technologies due to a growing supply of renewable energy. Although this paper provides lessons from countries which experienced problems with high share of renewable energy and started to promote energy storage alongside with renewable energy, the results will be useful for policy-makers from developing countries with a growing share of renewable energy in total electricity. https://doi.org/10.1016/j.egypro.2019.01.897

Presentation 2.      

 Title: Opportunities for collaboration and funding: Energy Studies Institute National University of Singapore (1 hour including Q&A)

Abstract: In this presentation Dina will provide a brief description about National University of Singapore including Energy Studies Institute. Dina will also explain application process for AUA Scholars Award and other research collaboration opportunities.

 

Presentation 3.      

Title: Accessing global renewable energy and energy storage data using Bloomberg terminal (1 hour including Q&A)

Abstract: Usually researchers think of Bloomberg terminal as a source of financial data from stock exchanges, for example Green Bonds or Green Sukuk. However Bloomberg also provides data on investments, costs, capacities and projections carefully collected from various sources. In this presentation Dina will provide an overview which energy data is accessible from Bloomberg terminal and how to find it. Four Bloomberg terminals are located at the NU Library and can be used by NU staff free of charge.
