Project 1: Optimization of the Antiperovskite Structure, Morphology, and Electrochemical Properties for LIB Solid-state Electrolytes and Nanocomposite Cathodes
Lead PI / Presenter: Dr. Alevtina (Alla) White-Smirnova (South Dakota School of Mines and Technology)
The total 2017 solid state battery market ($53M) will reach $1.4B by 2025 at 49% Compound Annual Growth Rate (CAGR) from 2018 to 2025. Even higher CAGR (54% from 2018 to 2025) is projected in Europe. However, the risk-adjusted CAGR can be lower due to prohibitive cost and insufficient performance of conventional solid-state electrolytes. To minimize these risks, the project is focused on optimization of a new class of glass-ceramic solid state electrolyte materials - antiperovskites. In comparison to other conventional solid-state electrolytes, e.g. garnets, antiperovskites are at least 50 times less expensive, and have significantly lower melting points (300-400 deg. C vs. >1600 deg. C for garnets) that enables battery manufacturing more economically viable. The objectives of this project are: 1) Comparative study of doped and undoped glass-ceramic antiperovskites and their material characterization, including compatibility with lithium metal; 2) Design of the dense nanocomposite cathodes based on the best performing antiperovskite electrolytes in regarding electronic/ionic conductivity and electrolyte-cathode interfacial resistance; 3) Electrochemical characterization of the electrolyte and cathode materials, and full electrochemical cells in a low-power battery prototype configuration (e.g. CR2032).
Project 2: Battery Remaining Useful Life (RUL) Model & Assessment and Online Battery Management System (OBMS) for Optimization
Lead PI / Presenter: Dr. Huitian Lu (South Dakota State University)
To ensure a highly reliable and safe application of the LIB power, the online (real-time) battery management system (OBMS) is essential. The base function of an Online Battery Management System (OBMS) is to ensure the optimum use of the battery energy that powers the portable devices and to minimize the risk of battery damage (e.g. optimization of battery life and performance). These functions are achieved by real-time monitoring and controlling the battery charging and discharging processes. In OBMS, the electrochemical models are used to provide a correlation with the reactions that occur in the battery to validate and control the state of charge (SOC) and the state of health (SOH) for the online assessment. The OBMS project will produce an online self-assessment model for the evaluation of the internal impedance, battery capacity, and the SOC/SOH. Furthermore, OBMS project will result in a self-assessment of RUL using performance protocols for decision making in regard to the system performance and optimization strategy. The OBMS adopts technology of sequential Monte Carlo optimal filtering based on state-space models. The OBMS will provide a real-time display of the system dynamics in correlation with the previously acquired data.
Project 3: Additive Manufacturing/3D Printing of the Next Generation All-Solid-State Batteries (ASSBs)
Lead PI / Presenter: Dr. Abu Md Numan-Al-Mobin (South Dakota School of Mines and Technology)
Additive Manufacturing (AM) and 3D printing technologies lead their way to the next generation of the all-solid-state energy storage. From 2013 to 2018 the worldwide revenues from AM / 3D printing increased from $3B to $12B, and will exceed $21B by 2020. Development of the AM / 3D manufacturing for all-solid-state batteries (ASSBs) will result in reduced manufacturing time and lower $/KWh cost. The companies equipped with this flexible manufacturing technology may obtain a competitive advantage over those using more expensive approaches. The AM / 3D technology opens new opportunities in terms of battery production paradigm and manufacturing capabilities. AM / 3D manufacturing will substantially reduce lead times, allow new designs to have shorter time to the battery market, and will permit customer demands to meet more quickly. The goals of this project are: 1. Develop and demonstrate the feasibility to fabricate batteries using AM / 3D processes as a game-changing technology, 2. Design and deliver a functional battery product, and 3. Demonstrate unique AM / 3D integration, processing, and packaging concepts to prove economic feasibility, reliability, and provide low $/KWh cost.
Project 4: Using Quantum Chemical Methods to Aid Materials Design
Lead PI / Presenter: Dr. Bess Vlaisavljevich (University of South Dakota)
High-performance computing and predictive computational modelling of a ceramics, glass-ceramics, and metal organic frameworks (MOFs) is essential for materials design to streamline their improvement and discovery for all-solid-state energy storage. In close collaboration with experiment, computational models provide molecular-level insights into the electronic structure, reactivity, and stability of materials. Specifically, density functional theory and ab initio molecular dynamics simulations will be combined with experiment towards understanding the key physicochemical aspects controlling energy transfer within phases and at interfaces. The team has expertise in multiconfigurational electronic structure theory and classical simulations, if the need to use these tools arises. The objectives of this project are to: 1) Provide computational guidance in materials discovery for the benefit of CEPS industrial partners; 2) Rapidily identify new materials for all-solid-state energy technologies; and 3) Elucidate structure-property relationships that can only be understood by a combined experiment-theory approach (e.g.the nature of lithum transfer at an interface or the adsorption of guest molecules in a MOFs).
Project 5: Grid-Compatible Power Electronics Converters for Wind and Photovoltaic Solar Systems
Lead PI / Presenter: Malek Ramezani (South Dakota School of Mines and Technology)
Renewable energy contribution to the global energy consumption experiences a projected steady growth of 30% until 2023 with 70% growth of solar and wind power generation. However, the conventional power grids are not designed for adopting such intermittent resources. High penetration of renewables necessitates their contribution and service to the grid at abnormal and critical conditions such as voltage sag, frequency sag, fault, etc. This project involves: 1) Study and analysis of local, national and international grid code requirements and critical services which shall be provided to the grid in order to facilitate the integration of residential and utility-scale solar and wind energy systems; 2) Development of the control and synchronization mechanisms for the interfacing power electronic converters to provide the required grid services in a plug-n’-play fashion to advance current practices; 3) Integration of the required hardware and standard tests to verify the developed concepts and practices.
