• Solid-state batteries
• Ideas to enhance battery safety
  

Na-ion batteries (SIB) are rapidly developing as potential alternatives to complement Li-ion battery (LIB) technology. The energy densities of SIBs are close to LIBs, but at the same time they avoid or reduce the amounts of many critical elements used for LIBs. Due to their conceptual similarity, SIBs can be produced on the same manufacturing lines as LIBs, which is a great advantage for market implementation. This tutorial gives an overview on Na-ion battery development, with the focus on materials (anode, cathode) and electrolytes.

Part 1 of this tutorial will cover cover critical techniques and analysis for extracting the maximum insight from standard electrochemical testing data

Topics include: 1) Theoretical Capacity and Standard Reduction potentials; 2) Charge, discharge V-T data; 3) Rest Potentials; and 4) Constant Voltage Charging. This tutorial will help you make the most of this data so that you can detect and remediate battery defects sooner.

Part 2 of this tutorial will cover in-depth tools and analysis capabilities for extracting maximum mechanistic insight out of electrochemical data.

Topics include: 1) dQ/dV; 2) Pulse Characterization; 3) HPPC; 4) GITT; 5) Analytical Pulsing Protocol (APP); and 6) Battery manufacturing analysis. This tutorial will help you make the most of this data so that you can detect and remediate battery defects sooner.

This tutorial will give an overview of battery systems design. An overall product development process will be discussed for a typical system. Design aspects of each individual subsystem will be explored with cost impacts of different design choices. Testing, validation, and designing for safety will be other key areas of discussion.

Considering the increasing interest in supply chain due diligence related to initiatives, such as the US Inflation Reduction Act and the EU Battery Regulation, the ESG aspect of raw material production is becoming more and more important. However, the ESG landscape is one that merges several highly specialist fields, which can be tremendously confusing to the many stakeholders of the automotive battery value chain. The objective of the tutorial is to provide participants with an understandable overview of some of the latest and key aspects of sustainability initiatives in the automotive battery value chain. What is the best mining assurance standard? What about life-cycle assessment? How do companies work to improve footprints? What is the potential for improvement going forward?

Batteries have become daily use components for many applications. New growing segments like EV and grid storage batteries extend the traditional ordinary battery applications. In the race for energy density, we shouldn't forget safety. For example, the Samsung Galaxy Note 7 battery safety case. Unfortunately, we face daily safety events with injuries and severe damage. This workshop focuses on portable, stationary, and automotive battery safety along the battery cycle life (acceptance, testing, assembly, use, transportation, and disposal). This training incorporates Shmuel De-Leon’s and others' experiences on battery safety, representing over 26 years of work in the field. The motivation behind the training is to provide attendees with the knowledge needed to safely handle the batteries in their organization and to support reduction in safety events.

Technoeconomic analysis is often thought to be synonymous with cost estimation, but it is also a powerful tool for guiding process and product R&D as well as assessing competing technology. This tutorial will illustrate the value of integrating technoeconomic analysis into new product and process development from laboratory to plant construction, focusing on the early stages of development when critical decisions such as process route selection must be made with limited data. Techniques for estimating capital and operating costs will be covered, ranging from simple analogies to more complex methodologies. Using the results to differentiate between process options and proceed from “What can we do?” to “What should we do?” will be highlighted. These concepts and methodologies will be illustrated with real-world examples based on the instructor’s 40+ years of industrial experience.

TOPICS TO BE COVERED: 

- Factors that impact successful commercialization of battery materials.

- Technological feasibility versus economic practicality-market need/company capability intersection.

- Technoeconomic analysis methodology, focusing on the critical early stages of a project where product design and process chemistry and development occur amid significant technical and economic uncertainty.

In this tutorial lecture, the development of state-of-the-art solid-state Li-ion and Na-ion electrolytes for all-solid-state batteries with emphasis on ionic conductivity and chemical and electrochemical stabilities will be discussed.

Precursor cathode active materials (pCAM) are the weakest link in the North American battery supply chain, despite being critical high-value components. To localize and strengthen the continent’s battery and EV industry, large new pCAM manufacturing facilities are being built or planned across North America, most of which will produce ternary chemistry pCAM. As of today, approximately 800,000 metric tonnes per annum of pCAM capacity is under development. 

This tutorial will begin with an overview of Li-ion cell design for performance and manufacturability, including contrasting the performance and characteristics of commonly used materials. The tutorial will then lead to a detailed review of Li-ion cell manufacturing, from incoming raw materials through final cell formation, aging, and shipment.

As the world’s biggest EDV market, Chinese xEV industry has become the most important pioneering target. However, specially planned economy, localized regulations, and multiple business models exist and make international companies’ decision-making more difficult. Therefore, this tutorial will try to provide a whole picture of the Chinese EDV battery market including policies & regulations, future forecasts, competitive analysis, battery technology strategies, upstream supply chain, and positioning for foreign enterprises.

The key challenges in the use of silicon-based anodes, as well as progress in the implementation of silicon and what can we expect in the future. The latest improvements in other battery components are required to maximize the benefit of silicon-based anodes.

Application of lithium-ion batteries (LIB) in electrified transportation and renewable grid is growing at a very fast pace for decarbonization of the passenger vehicles by 2035. Due to the characteristics of current LIB technologies, although rare, there is potential for thermal runaway and fires, as seen by recent fires in Tesla Model S, Chevy Bolt, and grid storage system in an Arizona Utility. 

By 2025 the original lithium-ion battery manufacturing industry is on course to reach $98 billion worldwide. However, with so many uncertainties, the recycling market has projections of $14 to $40 billion. Recycling must be economically sustainable with future $10/kg cathodes, can it achieve such a goal? A supportive recycling industry will be expected to (1) operate with end-of-life batteries as an asset (2) produce cost-competitive elements, electrodes, or electrode precursor materials, (3) safely address large-scale throughputs, and (4) accommodate low cobalt or no cobalt cathode formulations. This tutorial will comprehensively address technologies of pyrometallurgy, hydrometallurgy, hybrid approaches, and direct recycling. The instructor will introduce these and discuss them in light of cost goals and market realities.
