If a Lithium-ion Cell Can Operate for More Than 6 Months at 85°C How Long Can It Last at Ambient Temperature?
In a few of our recent papers, we have presented Li-ion cell designs with liquid electrolytes that give astounding lifetime at temperatures as high as 85°C. In fact, we have been testing these cells now at 100°C and they are operating well for more than one month so far. I will discuss what is required to make such awesome cells and then consider what their lifetime at ambient temperature might be. I will show that the energy density of these cells is very reasonable and that Co-free moderate-nickel designs also work equally well.
Next-Generation Batteries - An Update on Li Metal Battery and All Solid-State Battery
With the recent success in deploying lithium-ion batteries for light-duty passenger cars, it is time for researchers and scientists to work on a road map of next-generation batteries beyond lithium-ion. In this talk, I will give an update on the current status of research efforts in enabling lithium metal batteries and all solid-state batteries. A few cutting-edge scientific tools will be introduced, including X-ray CT, Cryo-EM, Titration GC, and more, all aimed at quantitative understanding of the failure mechanisms of next-gen batteries.

ADVANCED BATTERY DEVELOPMENT FOR MEDICAL APPLICATIONS
Craig Wohlers, Executive Director, Conferences, Cambridge EnerTech
Powering Medical Devices - Application Needs and Battery Technology Drivers
Medical devices including implantable, wearable, surgical tools, and hospital equipment are increasingly being powered by battery cells and packs. Innovations in primary and secondary battery technology have enabled advances in medical device technology. This presentation will describe current applications of batteries in medical devices and examine drivers for battery technology in future medical devices.
Miniaturization of Lithium Batteries
The proliferation of connected devices has led to a need for miniaturized batteries with reliable performance. There is a limit to how much conventional designs can be downsized before they become inefficient from a process and performance perspective. Novel design approaches have been developed that can be produced by a scalable process and provide reliable seals, high volumetric efficiency, and predictable performance.

Some Thoughts on Battery Quality
The first major Lithium-ion battery technology application was portable electronics. In today’s world Lithium ion has found its way into the vehicle and stationary power markets. This new market demand influences the quality of supplies available to the consumer market. This presentation is focused on lifelong quality and will discuss some general trends. The implications in the marketplace of these trends and the need for a holistic design approach in product and manufacturing. A few hypothetical situations will be used to illustrate the challenges.
Enhancement of Battery Sustainability by Charging Algorithms
Li-ion batteries are used in many industries, such as consumer electronics, electric vehicles, and internet-of-things. With the substantially increasing demand, sustainable battery technologies are desired. This talk explains several battery algorithms: adaptive charging, situational charging, context-based battery charging, etc. All algorithms extend battery longevity and require less battery replacement, thus contributing to sustainability enhancement.
Fast-charging advances in nanostructured electrode materials for cathodes and anodes. Includes an update on nanostructured Niobium anode, and introduces a Nickel and Cobalt free nanostructured cathode developed from NSF SBIR STTR Phase 1 development.

Overcoming Battery Systems Challenges for Consumer Electronics Applications
The 3C battery market consumes about 80GWh annually. It used to be the largest battery market up until 5 years ago when it was surpassed by the EV market. It looks to be going to 3rd place with the upcoming ESS market as well. How does this shift affect the 3C OEMS? What challenges will this place on them with resources, suppliers, and ability to innovate? The panel will discuss how these other battery markets will shape the 3C battery design and what changes need to take place in order for the 3C OEMS to stay abreast of new technologies.
Atomic Layer Deposition has shown to improve battery performance, using thin film coatings to modify interface surfaces. ALD coatings have been applied to cathode, anode, and separator materials to modify the surface interfaces, and improve battery performance. ALD has been studied for uses in battery applications on small scale batch systems. This presentation describes how Beneq developed a high throughput roll to roll ALD system for high throughput production scale manufacturing.

INNOVATION & DESIGN IN NEXT-GEN CONSUMER ELECTRONICS APPLICATIONS
Talk Title to be Announced
Outdoor power equipment, such as riding lawn mowers and snowthrowers, have traditionally been powered by internal combustion engines with very limited pollution controls and high noise levels. These environmental factors coupled with legislation mandating the transition to electric-powered equipment has made this industry a prime target for electrification. This presentation outlines a path to transforming an industry that will benefit consumers, professional users, and the planet.
Battery Electrodes: Nano- vs Micro-Structuring
In this talk, I will compare nano with micro-particle electrodes, and discuss why the battery industry is unlikely to replace micro with nano-size particles. Given this, I will address the question as to whether there is a place for nanomaterials in battery design. I will show that the way forward lies in micro-particles constructed by the assembly of nanoscale building blocks and in micro-particles with engineered or natural nano-porosity. Such multiscale particles offer exciting possibilities to develop the next generation of battery electrodes that are quintessentially both micro and nano with respect to their performance attributes.
The Effects of Fast Charging on Battery Performance
The increased power carrying capability of USB-C has enabled fast charging in many consumer products. When designing a battery into a product with fast charging capabilities, it is critical to understand the impact on battery functional parameters like cycle life, energy density, and more. Fast charging also has an influence on cost. This talk will address these tradeoffs and attempt to set reasonable battery performance expectations.
Gauging for the Applications with Dynamic Loads
Robotic vacuums, drones, electric lawn movers, and other self-moving devices require exact remaining run-time to return to charging port. However, predicting it is complicated by highly variable load patterns. For example, vacuum robot can run on power-hungry patch of carpet on normally hardwood floor. Basic gauging methods are highly inaccurate under such conditions, forcing to leave up to 30% of capacity in reserve - cost saved by correctly modeling usage patterns.
Beyond the 2024 Ban of Gas Outdoor Power Equipment
Beginning in 2024, California will ban all new sales of fuel-powered outdoor power equipment. Similar to autos, a traditional ICE industry showcases a boom in adoption towards alternative power sources with a focus on battery life-cycle processes. OPEI is an international trade association representing more than 100 manufacturers and their suppliers of gas and electric-powered outdoor power and transport equipment with domestic shipments of nearly 40 million products each year.
Impact of 5G Circuits on Battery Management System Reliability
While 5G changes how the world communicates, network or component failures are not an option. As data rates increase and latency decrease, critical applications are emerging that rely on the benefits of the network. Many of these applications may rely on portable or mobile devices that are powered by batteries that require failure resistant battery management systems.This presentation covers why critical applications are emerging and leveraging the benefits of 5G and discusses why reliability of a battery management system is now more critical at a printed circuit level. Number of different tests that can be performed to validate and qualify the battery management circuit board for its reliability robustness will be covered along with its benefits.
