Enovix BrakeFlow Technology: A Breakthrough in Next-Gen Battery Safety
Ashok Lahiri, CTO, Technical Advisor & Co-Founder, ENOVIX Corp.
Advanced, high-energy, Li-ion batteries need advanced features to improve abuse tolerance and reduce the risk of thermal runaway. The Enovix stacked cell architecture, which uses a silicon anode, upends the conventional paradigm and enables both an increase in energy density, and a high level of abuse tolerance to reduce the risks of an internal short, due to its BrakeFlow technology. With BrakeFlow incorporated, instead of a sudden catastrophic release of energy, the battery is designed to discharge safely and slowly.
The Battery of the Future Is Higher-Energy and Cobalt-Free
Evan M. Erickson, PhD, Founder & CEO, Administration, TexPower EV Technologies
Conventional wisdom tells us that cobalt is required in high-energy electric vehicle batteries, but is it true? All battery companies are trying to reduce their cobalt usage in a stepwise fashion. TexPower EV Technologies, Inc. leapfrogs this iterative process with zero-cobalt battery technology that does not sacrifice energy, power, safety, or any other performance metrics. The future of EVs is longer range, more affordable and cobalt-free.

Solid-State Battery Safety: From Calorimetry to Characterization
Alex Bates, PhD, Energy Storage Safety & Reliability, Sandia National Laboratories
The validity of improved safety often attributed to solid-state batteries has recently been investigated. Key findings indicate reaction pathways exist in SSBs which can release significant heat. That heat release may result in temperatures approaching, and in some cases exceeding those seen in thermal runaway of conventional Li-ion batteries. In this talk, characterization of abused SSB materials will be examined and correlated to differential scanning calorimetry heat flows.
Materials Design against Li-dendrite for Safer Fast-Cycling Solid-State Batteries
Xin Li, PhD, Associate Professor, School of Engineering and Applied Sciences, Harvard University
Solid-state battery is a promising next-generation battery technology. However, Li-dendrite across the solid electrolyte layer is one major safety concern. Electrolyte and electrode materials can exhibit a broad distribution of capabilities to suppress Li-dendrite growth, especially through the new mechanism of dynamic voltage stability. The talk will focus on strategies to design materials and battery devices for enhanced safety against Li-dendrite at fast charge and discharge. A combined approach of material synthesis, battery test and characterization, and computational modeling and machine learning will be utilized for the design across atomistic, materials, and device levels.

Development, Demonstration, and Performance of Li-ion/EDLC in-Electrode Hybrids for High Power Application in Pouch Cell Prototype Devices
Alexander Roberts, PhD, Associate Professor, Institute for Clean Growth and Future Mobility, Coventry University
With increasing demands in application, balance between power and energy requirements at cell level is increasingly difficult to satisfy, particularly in respect of higher power. This work demonstrates hybridization of battery and EDLC in-electrode with active materials from both present in both electrodes, as opposed to one electrode from each as seen in lithium-ion capacitors, enabling the tuning of power and energy to application and also increasing in lifetime.
Examination and Modeling of Thermal Runaway on Li-ion Battery Impact of Chemistry, SOC, and Aging
Sara Abada, PhD, Research Engineer, Modeling of Electrochemical Storage Systems, IFP Energies Nouvelles
Thermal Runaway (TR) of LiBs is the key to safety. It involves multi-scale phenomena ranging from internal physic-chemical mechanisms to battery components including safety features (CID, pressure disk, vent) and further to thermal propagation. At IFPEN, a Multiphysics Multiscale model is developed to be able to simulate the cell behavior under different initiation events (overheating, overcharging, short circuiting). The impacts of chemistry, SOC, and aging are studied.

Enhancing Battery Safety with Higher Operating Temperatures
Brian McCarthy, PhD, CTO, EC Power
Lithium-ion batteries have long been confined within narrow temperature thresholds, limiting their effectiveness and safety. This talk will explore a potential future where lithium-ion cells are intentionally engineered for higher operating temperatures and so revolutionize battery safety. By delving into cutting-edge advancements like solid-state batteries, which inherently thrive at elevated temperatures, we contemplate the possibility of harnessing higher operating temperatures as a design advantage rather than a limitation. We will also discuss the role that next-generation thermal management systems could play to facilitate this future.

Deploying Energy Storage Systems Safely in Urban Environments
Christina Lampe-Onnerud, Founder and CEO, Cadenza Innovation
Safety has historically been deprioritized, often in favor of cost, resulting in energy storage systems that cannot respond in time to prevent catastrophic explosions and fires. However, safe lithium chemistry-agnostic battery deployment and operation is achievable and essential (particularly in urban areas where electricity demands are the greatest and safety is paramount) to propel the clean energy storage solutions that will enable the successful transformation from fossil fuel dependence.
