Strategic defense and federal initiatives to secure the battery supply chain
ABSTRACT: The rapid expansion in demand for li-ion batteries in the commercial sector has led to a projection of over 6TWh in annual capacity in the near future. In the Defense sector, reliance on lithium batteries to support key operational capabilities has driven the Department to review its current posture with respect to policy, infrastructure, standardization, and supply chain security. The one year report to Executive Order 14017, Securing Defense-Critical Supply Chains, summarizes recommendations/actions the Department will take to address these challenges, in close coordination with Interagency partners.

U.S. Battery Supply Chains: Locally Charged?
ABSTRACT: Mr. Coffin and Mr. Horowitz will be discussing the U.S. EV battery supply chain, building off research from the Supply Chain for Electric Vehicle Batteries, and Supply Chain for EV Batteries: 2020 Trade and Value-added Update, which established a methodology for measuring value-added at different stages of the value chain from cell to vehicle, and analyzed existing battery trade data. They will also incorporate upstream trade data to examine the foreign sources for battery inputs which U.S. battery production relies on. Next they will examine the development of a domestic battery supply chain, including recent investments and joint ventures by vehicle manufacturers and challenges with onshoring the pre-cell portions of that supply chain.

Enabling High-Rate Lithium Metal Anodes by Tailored Structures and Interfaces
ABSTRACT: Oxide-based solid-state Li-batteries (SSLiBs) have the potential to be a transformational and intrinsically safe energy storage solution due to their non-flammable ceramic electrolyte that enables the use of high-capacity Li metal anodes and high voltage cathodes for higher energy density over a much wider operating temperature range. However, their progress has been limited due to electrode/electrolyte interfacial issues. In particular for Li-metal anodes concerns over dendrite formation/propagation and the requirement for elevated temperature and high stack pressure are still prevalent. To eliminate these concerns a rational design of tailored structures and interfaces in Li-metal anodes will be presented. In addition, progress toward full cells using these tailored structures and interfaces will be presented.

Aqueous solid polymer L-ion battery electrolytes: safely enabling high energy batteries with domestically sourced components
ABSTRACT: As use of lithium-ion batteries continues to grow, concerns over their safety, and more recently material supply chain security, have influenced research for alternative electrolyte materials. Our battery systems offer the opportunity to enable high energy cells using Si anodes with materials-level intrinsic safety, enabling domestic production, and improving supply chain security by utilizing domestically sourced materials. Solid polymer electrolytes (SPEs) offer a safer approach due to their inherit nonflammability, while offering decreased cost and weight, ease of processibility, and increased long-term chemical and mechanical stability. Our work builds upon the concept of plasticization of polymer networks with strong oxidative stability. Small-molecule “plasticizers” can disrupt inter- and intrachain interactions to reduce the overall crystallinity of the network, impart mobility to polymer chains, and reduce impedance for lithium-ion movement. By using water as a plasticizer, we can create aqueous SPEs that exhibit preferential Li + transport and high ionic conductivity. Inclusion of a second, non-aqueous solvating molecule can extend the electrochemical stability window (ESW).

Fluorinated Materials for Battery Electrolytes: Enablers and Key Challenges
ABSTRACT: Fluorinated polymers (e.g., PVDF) have long been used in Li-ion cells, as well as the critical salt LiPF6. PVDF is commercially being replaced by other binders, however, to enable aqueous electrode processing. But advanced electrolyte formulations by battery researchers have increasingly embraced the use of fluorinated materials. Such novel electrolytes may prove to be enablers for the more challenging active materials essential for ultra-high energy cells, but key challenges must be taken into consideration and perhaps overcome for commercialization of cells with these relatively new fluorinated battery materials.

Cathode supply chain considerations with focus on North America
ABSTRACT: The U.S. market for Lithium-ion batteries is forecast to grow by more than 10X by 2030 driven primarily by the electrification of light duty automobiles. Moreover, today’s battery market is supplied primarily by cathode manufactured in Asia. This dependence on global supply presents challenges that go beyond the existing supply chain concerns for raw material availability. Global automakers are investing $100’s Billions to adapt their businesses to the new electrified vehicle model including investment in necessary battery supply chains. This is resulting in transformation of battery supply chain to accommodate the unprecedented demand growth. The presentation will discuss cathode supply chain considerations with focus on North America.

Challenge of Supporting Lithium Battery with Domestic Suppliers
ABSTRACT: Demand for lithium batteries is rapidly growing worldwide. The supply chain to support the domestic & foreign production of lithium batteries is ramping up to meet the growing demand. The large volume battery needs are for electric vehicles. Not to be forgotten are the thousands of types of low volume batteries familiar to the extreme battery community--specialized batteries for defense, space, medical, and more. The presentation will survey the current landscape of U.S. companies supplying materials and components for domestic cell producers. The presentation will focus on understanding what is needed for U.S. battery materials, equipment, and software supply to ramp up domestic production for extreme batteries. EV's will also be mentioned.

Battery chemistries for relieving supply chain issues of today, tomorrow and day-after-tomorrow
ABSTRACT: Lithium-ion batteries have become the choice of power source for portable electronics and electrification due to their high energy density. However, with the rapid proliferation of battery technologies for electric vehicles and grid storage, cost, sustainability, and supply chain issues will be the single dominant factor as we move forward. Cobalt use is a problem today due to limited abundance and ethical concerns and air pollution associated with mining. Although nickel has become indispensable to replace cobalt, nickel will become a problem tomorrow, and as we move forward, any mined metal, including lithium, can be a problem day-after-tomorrow. This presentation will focus on battery chemistries that can progressively address or relieve these challenges.

High Safety, High Energy and High power LiVPO4F Battery
ABSTRACT: LiVPO4F is an intrinsically safer cathode material than other available cathodes such as Lithium Cobalt Oxide (LCO), Nickel Cobalt Aluminum Oxide (NCA), and Nickel Manganese Cobalt Oxide (NMC) because of the presence of PO4 group in its tavorite structure, which is similar to lithium iron phosphate. In addition, LiVPO4F has a higher energy density than LiFePO4 due to the higher lithiation/delithiation potential (4.2V) than that of (3.4V) LiFePO4. LiVPO4F does not have transition metals Co or Ni, which may increase in price as a large amount of Li-ion batteries with NMC and NCA, LCO cathodes are manufactured. With sponsor from ARL & CREB and collaboration from our cathode supplier, Saft is developing High Safety, High Energy and High power LiVPO4F Batteries for army applications.
