2023年のチュートリアル*

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.

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.

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.

Significant growth of lithium-ion batteries (LIB) for electrified transportation and renewable grid are expected in the next 10 years. Due to the characteristics of current LIB technologies, there is potential of for thermal runaway and fires as evidenced by recent fires in Tesla Model S, Chevy Bolt, and grid storage system in an Arizona Utility. Increase severity of fire incidents with more advanced energy-dense LIBs, especially cathodes with higher Ni and anodes with silicon or lithium is expected. In this Tutorial/Seminar we will 1. discuss fundamental causes for safety issues leading to thermal runaway and fire, 2. review abuse behavior of cells and packs through characterization, testing, and modeling/simulations, 3. provide overview of approaches that could reduce safety risks and detect impending failures, and 4. provide references as a resource for accessing more information. This tutorial/seminar is provided by Dr. Ahmad Pesaran with 25+ years of experience in lithium-ion battery R&D&D including safety testing and modeling with perspectives of his participation at USABC Technical Advisory Committee. He will provide the audience with information and understanding needed to handle Li-ion batteries safety in both their work at their companies and in products they deliver to the market.

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.

Na-ion batteries (SIB) are rapidly developing as potential alternatives to complement Li-ion battery (LIB) technology. The energy densities of SIB are close to LIB, but at the same time they avoid or reduce the amounts of many critical elements used for LIB. Due to their conceptual similarity, SIB can be produced on the same manufacturing lines like LIB, 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.

This tutorial will cover critical techniques and analysis for making sure researchers extract the maximum information out of standard electrochemical testing data.

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 other 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.

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.

Battery management systems must perform several tasks including estimating state of charge, state of health, state of power, and state of energy. Various approaches are available to accomplish these goals. This tutorial will give an overview of commonly used methods and discuss some of their individual advantages and disadvantages. Methods based on empirical equivalent circuit models will be highlighted but methods using physics-based models will also be introduced.
