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.

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.

Cathode micro-cracking is an important degradation mechanism in lithium-ion batteries. Using advanced x-ray imaging techniques, we can image microcracking in situ with unmodified commercial pouch cells. Using cells that were cycled for over two years, we show the dramatic effects of cathode microcracking at the particle-, electrode-, and cell-level. These tools are then used to quantify the extent of microcracking using different electrode materials and under different cycling conditions.

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 presentation will discuss StoreDot’s extreme fast-charging Si-rich anode technology evolution, the prototyping methodologies used, and the progress of performance over time, scaling up from 1Ah and 3Ah and to 30Ah large form factor pouch cell. This process resulted in exceeding the goal of 300Wh/Kg and 1000 consecutive extreme fast-charging cycles; These extreme fast-charging battery cells are currently undergoing testing by global EV OEMs.

Fast charging of lithium-ion batteries, being developed for electric vehicles, is needed to meet customer demands of time-parity with today’s gasoline-powered cars. This presentation is an overview of extreme fast charge studies being conducted at Argonne National Laboratory. Methodologies to monitor electrode polarization, detect Li-plating, examine lithium concentration gradients in electrodes, and investigate electrode materials changes, during and after exposure to high currents, will be discussed.

Motorsports require very high-power lithium-ion chemistry for both hybrid vehicles and electric vehicles to improve energy efficiency and fast charging capability. Saft already developed 400C rate high-power lithium-ion cell chemistry for hybrid applications, and high energy chemistry with 7.5C rate fast charging capability and 220 Wh/kg energy density. In this talk, we will give an introduction to cell and battery development, characterization, and accurate duty cycling testing.

SolidPAC toolkit is flexible, enabling the battery community to quantify the effects of materials' chemistry and fractions, electrode thicknesses and loadings, and electron flows on cell energy density and costs, and to use reverse-engineering concepts to correlate the cell energy density output of solid-state batteries to materials and cell design inputs.

Solid-state batteries are positioned to offer enhanced energy and power densities, system efficiency, and safety. These promised improvements are owed to the use of highly-conducting solid-state electrolyte SSE materials that eliminate the use of volatile electrolyte solvents and can have the potential to be compatible with a wide variety of desired electrode materials. In this presentation, we will discuss our efforts pertaining to designing and demonstrating new solid-state electrolytes that offer advantages over the current material systems. We also will outline remaining key challenges and offer future perspectives.

The lack of high performance and low-cost solid-state electrolytes has been a bottleneck of solid-state batteries development and commercialization. This presentation will highlight the latest advances of solid-state electrolytes development and manufacturing at Ampcera. Examples of the integration of Ampcera's solid-state electrolytes in solid-state batteries will be presented.

Whilst lithium-ion batteries are currently dominating the EV battery market, and will still improve for some years, it is expected that solid-state batteries will provide superior safety and operational performance, once fully developed. This presentation will describe the various solid-state chemistries and processes and how they compare. The outcomes of studies, carried out in collaboration with Ilika, will conclude on the equipment and resources required to build the "Solid-State Battery Factory" and how this compares to the equipment used currently in lithium-ion battery manufacturing plants. Ilika will finally provide its latest progress in developing solid-state batteries. 

Solid-state lithium batteries (SSLMBs) with promises of high energy density and safety are yet challenging in manufacturing due to issues like brittleness of solid-state electrolytes and interfacial stability with electrodes. 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.

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.
