Oxygen Vacancy for Energy Conversion and Storage Devices?: Shanqing Zhang1; 1Griffith University
Oxygen vacancy (OV) can be considered as a defect when the number of oxygen atoms expected in a compound is less (or missing) than what it should be in its perfect crystal lattice, it is known as In this talk, OV in titania and lithium titanate nanomaterials achieved via numerous ways (hydrogenation, cold quenching and chemical reduction) is characterized and applied for photocatalysis and lithium ion battery applications. The preliminary results suggest that the OV could bring about significant enhancement in energy conversion efficiency and energy storage capability and stability.

Electrochemical Engineering of Graphene Oxide for Wearable Smart Devices: Yu Lin Zhong1; 1Griffith University
While significant progress has been made on developing an electrochemical route to GO, existing methods have key limitations regarding their cost and scalability. To overcome these challenges, we employ a combination of highly robust boron-doped diamond (BDD) with a wide electrochemical potential window and commercially available fused deposition modelling (FDM) 3D printing to fabricate a scalable packed-bed electrochemical reactor (PBER) for GO production. The simplicity, cost-effectiveness and unique EGO properties make our current method a viable contender for large-scale synthesis of graphene oxide. Subsequently, we have demonstrated a new efficient technique for 3D printing of conductive PDMS/graphene ink by using an emulsion method to form a uniform dispersion of PDMS nanobeads, EGO and PDMS precursor binder. The formulated nanocomposite ink exhibits high storage moduli and yield stress that can be employed for Direct Ink Writing (DIW) 3D printing.

Bio-inspired Superhydrophobic and Superhydrophilic Materials: Ziqi Sun1; 1Queensland University of Technology
Superhydrophobic and superhydrophilic surfaces have been extensively investigated due to their importance for industrial applications. It has been reported, however, that the superhydrophobic/superhydrophilic surfaces are very sensitive to heat, ultraviolet (UV) light, and electric potential, which interfere with their long-term durability. Biological species in nature have developed unique structures and functions very close to perfection to suit their specific living environments after millions of years of evolution and selection, which offer us excellent inspirations on developing artificial nanomaterials with extraordinary properties. In this study, we introduce a novel approach to achieve robust superhydrophobic/superhydrophilic surfaces by designing architecture-defined complex nanostructures by learning from natural species. Bio-inspired nanostructures with designed wetting behaviors have been successfully fabricated by mimicking the natural structures, such as fish scales and fly eyes. The unique surface properties of the bio-inspired nanostructures open a new way to design novel multifunctional nanomaterials.

Integrated Sensor Network and Battery Management System for State of Health Estimation and Safety Control of Lithium- ion Batteries: Bing Li1; Vikas Tomar1; Thomas Adams2; Corey Love3; Vilas Pol1; 1Purdue University; 2Naval Surface Warfare Center; 3U.S. Naval Research Laboratory
Despite its wide application, safety and reliability of lithium- ion battery (LIB) remains as public concerns nowadays. There are numerous reports on unexpected LIB failure and accident, including severe capacity drop, explosion, etc. Due to the complex nature of battery composition, structure and working condition, there is limited research relating LIB degradation with change within the batteries. Although battery management systems (BMS) are widely applied, the data collected by BMS is limited and cannot well represent the battery state of health (SOH). In this work, a sensor network was developed with resistance temperature detector, eddy current probe, shunt resistor and BMS chip to provide a comprehensive understanding of SOH degradation during the service in dynamic environment described in NAVSEA 9310 testing standard. The LIB performance degradation and potential failure were correlated with change in battery structure and composition, and a model for SOH estimation and failure prevention was developed.

The Impact of Solar Thermal Resource Characteristics on Solar Thermal Pre-heating of Manganese Ores: Susanna Hockaday1; Reiner Buck2; Martina Neiseis-van Puttkamer2; Willie Smit3; 1MINTEK; 2DLR; 3Stellenbosch University
The proposed paper evaluates an alternative ferromanganese production flowsheet seeking to preheat manganese ores with concentrating solar thermal energy to 600 °C with heated air being the heat transfer medium. The benefits of solar thermal preheating will be evaluated based on a cost discounted economic model taking into account the variability of the solar resource, capital costs and operating costs of a solar thermal plant as well as the preheater over the lifetime of the project. Solar variability will be discussed based on possible implementation sites for such technologies and the cost and benefits of thermal storage in the flowsheet will also be evaluated.This work is part of the PRéMA project, aiming to advance novel energy systems in the drying and preheating of furnace materials. The PRéMA project has received funding from the European Union’s Horizon 2020 Research and Innovation Programme under Grant Agreement No 820561.

The Compatibility of Metallic Thermal Storage Materials and Housing Materials: A Computational Survey and Accelerated Reaction Experiment Results: Anthony Rawson1; Tina Gläsel1; Benedikt Nowak1; David Boon1; Veronika Stahl2; Florian Kargl1; 1Institute of Material Physics in Space, German Aerospace Centre (DLR); 2Institute of Vehicle Concepts, German Aerospace Centre (DLR)
Metals can provide an energy dense, high conductivity solution to the problem of storing heat latently in electric vehicles for space heating. However, many molten metals will react with container materials (e.g. stainless steel) when held for long periods at high temperatures. In this work, a computational and experimental method are introduced and results presented for the compatibility of the eutectic alloy Al-12.7 wt.% Si with a number of potential container materials. Several promising new container materials are identified from a survey of two CALPHAD databases. Sodium silicide and vanadium silicide were identified as compatible at equilibrium and both viable options as they have been applied as coatings on steel in past work. Experimental results for static pellet compatibility tests for periods of up to two weeks are given for several other materials and are shown to conform to literature and computational predictions. Recent developments in experimental apparatus for simulation of thermal storage materials undergoing erosive-corrosive wear are briefly discussed, providing an outlook for future research at the German Aerospace Centre (DLR).

Optimization and Management of On-site Power Plants Under Time-of-use Power Price: A Case Study in Steel Mill: Xiancong Zhao1; Huanmei Yuan2; Zefei Zhang2; Hao Bai2; 1Peking university; 2University of Science and Technology Beijing
The implementation of time-of-use (TOU) power tariff in Chinese steel industry provides an opportunity for steel mills to reduce electricity bills through an optimal collaboration between the on-site power plant (OSPP) and energy storage equipment(gasholders). In this paper, a mixed-integer linear programming (MILP) based scheduling model was proposed to achieve the optimal operation of OSPP and gasholders in a steel mill under TOU tariff. Compared with previous models, we considered the influence of TOU power tariff on the optimal scheduling of OSPP. The results of a case study demonstrate that the optimization model can achieve better peak-valley shifting of the electricity generation and decrease the electricity purchasing cost by 7.5% with improved gasholder stability.In addition,the overall power generation efficiency by can be increased by 2.13% using the proposed model, which indicates that the byproduct gases can be effectively and efficiently used.
