This presentation discusses the motivations and the testing methods that support them. Most testing methods are common to all these motivations, but the data are collected and used differently. This presentation gives some clarity to the complexities of battery testing and how resources can be efficiently used to achieve more with better test planning.

Many computing devices that use batteries can enhance system performance by peak-power mode. In this mode, system extracts higher current from a battery for a short period. While this makes computing speed faster, arbitrary peak power may cause battery degradation. This session talks about a method to enable peak power mode while mitigating battery degradation.

Supply of Li-ion battery has turned to surplus since 2019 due to the production capacity expansion and EV subsidy facing out. Battery cell manufacturers are seeking new customers and applications in order to increase their cash flow. Portable home appliances become an attractive sector due to the exponential growth in demand and short payment terms. However, the product requirements of home appliances are different from EV, and new cell technology and design are required. Hence, a new trend in cell technology and product development strategy are evolving. Analysis of this dynamic situation, technical advancement, and business opportunity will be presented in detail.

Medical device applications have various unique needs for batteries. This brings challenges to battery design, medical device and application design, supply chain design and management, and lifecycle management. This presentation will provide the product managers, medical solution and service architects, design engineers, and procurement leaders with an overview of the best practices of design, supply chain management, data and lifecycle management, and quality assurance that should be taken into consideration for medical device applications to benefit the customers and to deliver business objectives.

The growing wearables market accounts for 100’s of millions of batteries each year. The small footprint of wearables and growing customer expectations of them present unique challenges for battery performance, design, manufacturing, and safety compared to larger secondary batteries found in phones, tablets, and laptops. We will discuss some limitations and advantages, as well as the advances required to meet the demands of future wearables.

Prediction of remaining capacity is less meaningful than prediction of number of pulses. In addition, power tool applications have a series of challenges related to the need of fast charging while achieving acceptable cycle life. This presentation covers the key aspects of gauging and fast charging for highly intermittent load applications.

Formerly niche battery applications have grown considerably since 2016 and continue to be a profitable space for those suppliers willing and able to meet some extreme requirements. Two interesting product categories will be discussed in this presentation, each with its own specific challenges.

This talk will include: 1) determining the electrolyte imbibition rate in LiNi0.5Mn0.3Co0.2O2 cathodes, graphite anodes, and separators; 2) processing effect on electrolyte wetting; and 3) how the pores are filled with electrolytes.

Fast charging is a highly desired feature in many applications. This talk will overview results of fast charging using several different protocols. For each protocol, questions such as how long does it take to charge and to what state of the charge the cells get to will be answered. Once a particular protocol is identified to be the most optimal, further experiments can be done to understand impact on safety and aging.

Michael will be available to take your questions from his live tutorial given earlier in the day. A recording of the tutorial is scheduled to be available for on demand viewing by 10:00am on July 30, 2020 and the original live broadcast will take place at 7:30am - All Times Eastern Daylight (UTC-04:00)

As EV and Grid applications grow and dwarf the consumer electronics, light industrial and medical appliance industries in the use of batteries, the criticality of materials becomes more important. Critical does not mean scarce. Beyond this are the needs for materials that are ethically derived, and used sustainably, which requires a measure of recycling. Where possible, battery materials and or battery use should be directed towards carbon abatement strategies.
