Battery Ageing – How Modeling is Used to Predict Battery Life
Battery modeling and simulation makes it possible to analyze multiple operating conditions and design parameters for batteries and other electrochemical systems and processes. By developing mathematical models you can begin to understand the interaction of electrochemical and chemical processes in the battery and how these processes affect the performance and life of the battery.
In this presentation, we will take a look at the benefits of modeling and simulation in the design, selection, and operation of a lithium-ion battery. We will especially take a look at how modeling can be used together with testing. These results provide manufacturers and application experts with the data to not only predict battery life but to analyze the implications of design parameters and operating conditions to better understand the limitation of the battery.
This webinar will focus on the following key topics:
• Benefits of modeling and simulations in the design, selection, and operation of a lithium-ion battery
• Implications of design parameters and operating conditions with respect to experimental observations of battery performance, aging, and battery safety
• How battery modeling can be used together with testing

Recycling of Lithium Ion Batteries From Electric Vehicles
The recycling of lithium-ion batteries – from EVs and others – will be discussed in this webinar.
Recently, the pilot plant of project LithoRec II could prove that a newly developed combination of process steps enables the recovery of a mass fraction of 75 % and more on a material recycling basis from lithium-ion batteries. This is supposed to be much better than state of the art. Combining different process steps like discharging, dismantling, shredding, sifting and air-jet separation the project partners were able to achieve their goal: proving that lithium-ion batteries can be recycled better. One interesting process dealing with the electrolyte came in a black box (which was actually white) and this was because of another ongoing patenting process of Lion Engineering. A modified and simplified process works to directly recycle scraps from the production of lithium-ion batteries – in order to protect both: the environment and the stakeholder’s money.
This webinar will focus on the following key topics:
• Recycling of Lithium Ion Batteries
• Recycling Yields and how to regain 75% and more – on a material recycling basis
• Direct Recycling of LIB-Production Scraps

Battery Selection Tutorial Course 3/3: Integrating Your Battery Into Your Product – Designing for Worst-Case Scenarios
The last part in Exponent’s three-part series, this webinar will focus on the finished product from the viewpoint of the battery. How can you best protect your battery within your device? Is your battery going to be user-replaceable? If you’re creating multi-cell packs, how should they be separated from (yet still connected to) each other? Should a thermal event occur, how can you prevent that from cascading through the whole pack? This webinar will help to answer many of those questions, and discuss design questions to help safeguard your battery pack throughout its entire lifecycle.
This webinar will focus on the following key topics:
• Creating multi-cell packs
• Containing thermal runaway events

Stability of Li7La3Zr2O12 Garnet Solid-State Electrolyte Against Metallic Lithium
Energy storage demands will require safer, cheaper and higher performance electrochemical energy storage. While the primary strategy for improving performance has focused on state-of-the-art Li-ion batteries, this work seeks to develop solid-state batteries employing metallic Li anode. Recently, the ceramic electrolyte, Li7La3Zr2O12 (LLZO) cubic garnet, has shown promise owing to its unique combination of properties such as high Li-ion conductivity and electrochemical stability. Generally, LLZO is synthesized through powder processing and sintering at high temperature to produce dense membrane. Processing of the ceramic materials produces internal and surface flaws which will inhibit lithium transport creating localized current density and control the stability against Li dendrite propagation. This presentation will discuss new improvement in methodology to evaluate the integrity of LLZO membrane.
This webinar will focus on the following key topics:
• Methodology to evaluate the integrity of LLZO by identifying the microstructural flaws and their impact on mechanical properties
• DC cycling, EIS, XPS will be shown to determine the reactions that govern the maximum current density
• Correlate the electrochemical stability and critical current density with defects in polycrystalline solid state LLZO electrolyte
