Flexible Li ion Batteries via Nanocrystal-Nanocarbon Scaffolded Structures

Li ion batteries have fuelled a revolution in the development of electronic gadgets such as smart phones, laptops and miscellaneous devices which in turn have transformed human perception of the world in unprecedented ways. These electronic devices are mostly powered by Li ion batteries, and as these technologies evolve further, Li ion batteries also need to evolve to meet increasingly stringent standards and conditions for their sustained applications. Recently, one particular trend is the emergence of flexible electronics ranging from wearables and smart cards to body-worn health monitors and humanoids. To support the development of these further, Li ion batteries need to be physically flexible and highly performing and capable of delivering simultaneously the functionality, compatibility, reliability and longevity. This project has been focused on the development and characterisation of novel material platform (namely nanocarbon and nanocrystal) by demonstrating their use in the next-generation batteries and by enabling a new understanding of the complex battery electrochemistry to guide the design of energy materials and fabrication of battery electrodes. To this end, this project has provided timely opportunities to contribute to research programs that have achieved new design and fabrication method for flexible batteries with ultra-thick electrodes offering battery performance beyond the state-of-the-art. Further, applying rigorous methodologies for battery characterisation via the use of battery advanced diagnostics tools (e.g. operando neutron depth profile and operando x-ray) has shed new light on battery electrochemistry (including post Li ion chemistries such as lithium-oxygen and lithium-sulphur), thus developing new design principles for next-generation batteries with improved energy density, mechanical pliability, cost-efficiency, battery safety and longevity. These can also be extended to design electrode materials and batteries for electric vehicles and grid-scale storage, thus aiding adaptation of renewable energy.

Цел на проекта

The aim of this proposal is to develop next generation flexible high-energy density Li ion batteries. This project seeks to advance this field by developing generalized methodologies to effectively interface flexible nano carbon scaffolds with inorganic nanocrystals, and to obtain tailor made hierarchical assemblies as building blocks. Fabrication of these hierarchical materials whose chemical and mechanical properties can be optimized at the nano, micro and millimeter scale are key to ensure both high energy and power density, and structurally flexible components. Our strategy will significantly increase the loading of electro-active particles (nanocrystals) and maximize their contact/exposure to electrolytes in optimized conditions, which will improve the electrochemical properties of nanostructures. Parallel, by applying in situ electrochemical-Li-NMR-Neutron depth profile and XRD, the proposed multi-scale approach will deepen the understanding of fundamental issues such as Li+ diffusion path ways in nanocrystal-carbon scaffolded structures (Li ion kinetics), volume expansion of nanocrystals (stress/strain issues), thermal management (heat dissipation), gas evolution (via electrolyte decomposition) and various modes of particle degradation during battery charge/discharge cycling.
