Engr. Marcel Roy Domalanta and Assoc. Prof. Julie Ann del Rosario-Paraggua publishes an article on MDPI Energies titled, “A Multiphysics Model Simulating the Electrochemical, Thermal, and Thermal Runaway Behaviors of Lithium Polymer Battery”.

Understanding how a battery reacts to various circumstances, such as modifications in temperature, current, and state of charge, can be aided by battery modeling. The electrochemical, thermal, and thermal runaway model is necessary to better understand a battery's performance. This model takes advantage of the strong correlation between a battery's performance and temperature to optimize its design and structure under different conditions, such as charging and discharging. Non-uniformity of current density distribution and high heat generation present challenges that decrease specific energy and power, reduce the battery's life cycle, and make it unreliable and dangerous. Therefore, developing a comprehensive model that can provide insights into the battery's thermal mechanism to improve its performance, longevity, and safety is vital. The importance of studying a battery's thermal behavior cannot be overstated, as optimizing its design and structure is essential to ensure its safe and effective operation.

A multiphysics model was developed for an LCO-graphite-PVdF-HFP pouch LiPo battery. The electrochemical model can be adapted to different chemistries by modifying physical properties, and geometric changes can optimize battery design. The simulation showed shortened voltage plateau regions at higher discharge currents due to higher polarization. Simulated thermal behavior exhibited an RMSE of 1.5 K at 1 C discharge with an average heat generation of 0.90 W m⁻³. The reversible and irreversible heat generation was successfully determined, and temperature lowering by heat absorption was primarily due to reversible heat. The thermal runaway model showed that thermal abuse at 423.15 K triggers runaway with cathode-electrolyte reaction as the primary heat source, reaching a heat generation of 5.7 × 108 kW m⁻³. The model can serve as an initial bird's-eye view of predicting battery behavior, but extended numerical simulations and sensitivity analyses are recommended to optimize battery design and enhance model reliability.

NAST PHL invites Prof. Ocon to Innovation Series as Resource Speaker

By Mecaelah Palaganas • 12 Apr, 2024
The National Academy of Science and Technology Philippines (NAST PHL) conducted a three-part webinar series on the Innovations for Human and Planet Health and Security to promote open innovation and collaboration as a defining factor of socio-economic development. Highly esteemed NAST members of the representative divisions of various fields in science, awardees, and experts were invited to tackle the current innovation ecosystem of the Philippines and the innovative solutions that address food security and climate change. Aimed to promote multidisciplinary discourse and partnerships, the event was participated by researchers, policymakers, government officials, and the general public. Among the prestigious roster of resource speakers was Prof. Joey D. Ocon who delivered his talk on “Next Generation Batteries and Green Hydrogen with Renewables: Opportunities in the Clean Energy Transition” during the third segment of the NAST PHL Innovation Series. Prof. Ocon shared insights on the crucial role of energy storage technologies in the transition to renewable energy sources and the scalability of energy systems that can help satisfy the energy demand in the country. As part of the vertically-integrated R&D agenda of the Laboratory of Electrochemical Engineering (LEE), he also introduced water electrolyzer technologies involved in the production of Green Hydrogen. Moreover, the research facilities in LEE such as the CHED-LAKAS funded Hydrogen as Vector for Energy (HyVE) Research Facility and the DOST-NICER funded Advanced Batteries Center, both of which are first of its kind within the country, were highlighted as well as their capabilities and future endeavors. In the area of commercialization, Prof. Ocon discussed the multi-scale approach of the startup Nascent Technologies Corporation and its mission on industrial decarbonization by providing technologies and solutions for various energy storage applications. Through information dissemination in his thematic talk, more innovators and collaborators can come forward in support of the vision of the ongoing projects led by Prof. Ocon and devise integrative innovations that can contribute to the clean energy transition in the Philippines.
