Li-ion batteries are used in many industries, such as consumer electronics, electric vehicles, and internet-of-things. With the substantially increasing demand, sustainable battery technologies are desired. This talk explains several battery algorithms: adaptive charging, situational charging, context-based battery charging, etc. All algorithms extend battery longevity and require less battery replacement, thus contributing to sustainability enhancement.

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.

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.

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.

Latent heat thermal energy storage (LHTES) systems using phase change materials (PCMs) have appeared as promising solutions for energy storage when harnessing renewable energy sources in a wide range of engineering applications. The present study focuses on the design of horizontal shell-and-tube PCM-based LHTES systems capable of simultaneous charging and discharging in solar domestic hot water (SDHW) applications.

We report a novel impedance analysis method for quantifying the conductivity of electrons flowing through conductive materials in a lithium-ion battery electrode slurry. This method consists of a novel algorithm that identifies three key indicators for the negative electrode slurry and describes the electrical properties of the electrode slurry. We demonstrated excellent correlation between our algorithm and experimental data derived from Nyquist (Cole-Cole) curves.

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.

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.
