Meeting the demand for reliable energy storage, this work presents a machine-learning model for precise cycle life prediction in lithium-ion batteries (LIB). It explores battery aging features, utilizes data-driven methods for health assessment, and applies machine learning to predict cycle life. To address data limitations, synthetic data generation is employed, enhancing prediction accuracy. The presentation concludes by demonstrating the practical deployment of the proposed ML model for accelerated degradation prediction (for battery cell development and manufacturing feedback) and onboard deployment of low data AI on in-operation energy management. Discussions cover crucial aspects such as battery aging, data-driven health measurement, and the model’s versatility in handling accidental effects during operation.
This webinar will focus on the following key topics:
• Accelerated degradation based on low data AI for battery development for targeted applications
• Data-driven insights: machine learning for battery state of health assessment
• Prediction of rejection thresholds during cell manufacturing for application oriented cell development
• Prediction of targeted C-Rates for specific device applications
• Real-world impact: practical deployment of low data ML during real time device operation

Understand and Prevent Battery Fires and Explosions – and Avoid Costly Failures Like the Samsung Note 7
Modern batteries (eg Li-Ion) contain hazardous chemicals & they heat up during use: this combination always has the potential to cause fires & explosions. This presentation will focus on improving the understanding of how these incidents occur, what can be done to avoid them & how the risk can be minimized during early stage design.
The Samsung Note 7 phone & Boeing Dreamliner airplane fires are very costly examples of how even large corporations fail to understand the potential fire risk of batteries.
The solution lies in knowledge of heat generation rate during normal use & information about safe boundaries such as temperature, discharge rate & overcharge, in realistic situations that represent actual use conditions. Data from commercial batteries of different types will be used to illustrate these points.
A relatively new technique will also be discussed with data, which allows total heat output during discharge to be measured on-line and this can be used both for design and battery modelling. Examples of the data will be provided.
This webinar will focus on the following key topics:
• Why battery fires & explosions occur
• How to design safer batteries though understanding of heat generation
• Video evidence of batteries under explosive conditions
• How better thermal management systems can be designed – based on heat measurement from isothermal calorimetry
• Laboratory instruments suitable for testing and data generationPresenter

Preventing Thermal Runaway in Energy Storage Systems (ESS)
From air transportation to electric vehicles and most recently “Hover Boards”, our industry is painfully aware of the over-discharge malfunctions associated with high-energy lithium-ion batteries, yet according to recent studies, nearly 70% of all Energy Storage Systems currently deployed are lithium-ion. Avoiding the pitfalls of utilizing greater energy density in larger installations is what will be discussed. Michelle will walk through the recent innovations from materials and process tracking in battery manufacturing to comprehensive control of cells in a fully deployed system. Incorporating lessons learned from recent failure investigations by the NTSB and FAA as well as new DoE mandates, Michelle will discuss how to achieve and in some areas surpass the new emerging safety certifications for a multi-megawatt energy storage system.
This webinar will focus on the following key topics:
• Making batteries safe or making safe batteries? (control & mitigation)
• Cell manufacture tracking, certification and response
– NTSB & DoE analysis and current situation
• Incorporating advanced battery management systems (BMS)
– Active cell dynamic balancing
– Cell replacement (hot-swapping)
– System reconfiguration
– Energy density scalabilityPresenter

Maximizing Battery Performance and Reliability for Electric Vehicles and Energy Storage
FREE Webinar – Voltaiq is a proud sponsor of this event.
As automakers and utilities transition away from non-renewable energy sources, batteries have become essential for efficient energy storage and delivery. Companies are working intensely to deliver higher capacity and more robust batteries to power their products, but ad hoc development processes cannot keep pace with the volume of battery data being generated. In addition, understaffed battery development teams are unable to leverage their data to accelerate development or improve production and manufacturing.
In this webinar, we will outline the challenges that the battery industry is facing and how big data analytics can virtually eliminate manual data management and provide powerful capabilities that deliver rapid insights into a battery’s design that dramatically accelerate the development process and results in products with greater performance and reliability.
This webinar will focus on the following key topics:
• Recognizing the challenges and bottlenecks in battery development today
• Automating the battery data collection, data cleaning, and data management process
• Identifying design issues earlier with predictive analytics
• Leveraging metadata to understand the impact of materials, processes and test conditionsPresenter

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 electrolytePresenter
