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.

TRANSLATING FROM THE BENCH TO PRODUCTION
Mary Ann Brown, Executive Director, Conferences, Cambridge EnerTech
Translating Research Data into Battery Metrics
Translating research data into battery metrics (e.g., Wh/L, Wh/kg, $/kWh, etc.) is important for understanding the potential of newly proposed materials to compete with current lithium-ion technologies. The Battery Performance and Cost (BatPaC) Model is a free tool from Argonne National Laboratory, which translates lab-scale results into battery-scale performance. This talk highlights the use of BatPaC for understanding the main factors driving the translation from research data to battery metrics.
Accelerating Cell and Process Development with Ultrasound Inspection and Machine Learning
In this talk, we demonstrate the use of ultrasound inspection and machine learning to rapidly iterate through multi-variable designs of experiments, specifically in electrolyte fill/soak and SEI formation process steps. We discuss ultrasound inspection’s ability to assess the impact of electrolyte formulation, soaking time, formation protocol, and condition choices on cell quality, without the need for long-term cycling. We enable LIB cell and process development to optimize process conditions to quickly ramp up implementation into production.
Sionic Energy has taken a complete “system approach” to lithium-ion batteries, creating a full battery technology platform for the next generation of high-performance batteries. The silicon anode/nickel-rich cathode chemistry is widely regarded as the highest energy Li-ion system. Sionic batteries enable low cost Si materials for high-capacity anodes, high-energy nickel-rich cathodes, safe electrolytes and delivering dramatic enhancements in energy, life, safety, and cost.

SAFETY CONSIDERATIONS FROM CELLS TO PACKS
Battery technology research needs to move quickly to enable rapid scaling of the North American and Global supply chains. Using NOVONIX’s own high-throughput Ultra High Precision Coulometry (UHPC), a nimble, highly repeatable R&D-scale pilot cell line, and expertise in anode, cathode, and electrolyte material development, we will share how to leverage the right testing and R&D approaches to move the industry forward faster through material, cell, and process/manufacturing development stages.
The Consequences of Cathode Microcracking at the Particle, Electrode, and Cell Level
Cathode micro-cracking is important degradation mechanism in lithium-ion batteries. Using new x-ray imaging techniques developed with Jeff Dahn we can now image micro-cracking in-situ using commercial pouch cells. This work is of interest to both battery materials scientists and cell engineers as it shows how a material-level failure mechanism has significant and practical consequences for cell engineering demonstrating the dramatic effects of cathode micro-cracking propagate throughout the cell at the particle, electrode, and cell level. It also provides a case study for how newly-developed imaging methods can be used to better understand micro-structural changes in commercial form-factor cells.
2023 Global Regulatory Compliance Update
2023 Global Regulatory Compliance Update will provide a comprehensive look at the regulatory landscape in 2023 for small format battery packs in the global markets. We will provide details on the global markets that have current mandatory and voluntary requirements, what these requirements entail, and talk through some of the things to look out for in each case. The focus of the presentation will be limited to small format batteries for use in mainly consumer electronics as well as the safety requirements.
The development of a safe lithium-ion battery is crucial for the future of electrification. Nanotech Energy revisited the design of lithium-ion battery electrodes, electrolyte and separators to develop a novel battery concept that is competitive in both safety and cell performance. This talk presents our efforts in the development and production of a battery with dramatic improvements in achievable energy density, cycling life, operational temperature window and, more importantly, safety.

Lithium Ion Batteries Development for Motor Sports: High Power, High Energy and Fast Charging
The motor sports require very high powerful lithium ion chemistry for both hybrid vehicle and electric vehicle to improve energy efficiency and fast charging capability.

In this talk, we will give an introduction on the cell and battery development, characterization, and accurate duty cycling testing.
For Solid-State Batteries to penetrate the Electric Vehicle market will require a competitive pack cost and this is highly dependent on the cost and scalability of the electrolyte employed.

In this talk, I will present our recent advances in additive manufacturing of SSLMBs, including selective laser sintering for garnet-type solid state electrolytes, and direct ink writing for polymer electrolyte based SSLMBs.
The Rise of Polymers as an Essential Component of Solid-State Batteries
State-of-the-art Li metal solid-state batteries show huge promise but ceramic or sulfide electrolyte-based batteries still face significant hurdles before they can be produced in large volumes with the performance and cost profile the industry needs. This talk will look at the roles polymers can play in solving many of those challenges and how using polymers can enable the industry to move toward manufacturing low-cost, next-generation EV batteries at scale.
