The members of the Laboratory of Electrochemical Engineering participated in the 44th Annual PAASE Meeting and Symposium , held from July 15-17, 2024 , at Charles Fuller Baker Memorial Hall, University of the Philippines – Los Baños, College, Laguna . This year's symposium, themed “Filipino Scientists Across Borders: Towards Developing Regional S&T Innovation Ecosystems” with a subtheme of “Technological Innovations Towards Health, Food, and Nutrition Security,” was part of a broader series of events highlighting technological advancements in agriculture, sustainable education, artificial intelligence, and disaster risk reduction and management. These events were also held in Rizal, Batangas, and Leyte. Hosted by the Philippine-American Academy of Science and Engineering (PAASE), a distinguished non-profit organization comprising scientists and engineers of Philippine descent, the event was spearheaded by PAASE President Dr. Gladys Cherisse J. Completo. Aligning with PAASE’s mission to advance science, engineering, and technology, the symposium featured plenary talks and parallel thematic sessions from notable speakers worldwide, as well as local government representatives. The members of the Laboratory of Electrochemical Engineering made significant contributions by actively presenting their research studies during the Poster Exhibit. Notably, Jaira Neibel Bamba and Honesto Ovid Tubalinal were selected for the Rapid-Fire Presentation, where they effectively communicated their research on sustainable energy within a five-minute timeframe. A standout moment was the presentation of the annual Severino and Paz Koh Lectureship Awards in Science and Engineering. Prof. Joey D. Ocon , who received the award in the field of engineering, delivered an insightful lecture titled “Vision to Action: Advancing Battery and Hydrogen Technologies for a Sustainable Future.” His presentation ignited inspiration and motivation among the audience, particularly encouraging the researchers of LEE to embrace their roles in advancing sustainable energy solutions. Overall, the symposium not only showcased the considerable progress being made across various scientific disciplines but also reinforced the importance of international collaboration and innovation. By fostering a platform for cross-border exchanges and the presentation of cutting-edge research, the event played a pivotal role to the advancement of both regional and global scientific and technological ecosystems.

To equip more Filipinos to advocate for equal access to electricity, the Center for Energy Research and Policy (CERP) launched its inaugural energy roadshow, "Watts UP: CERP Sparks Dialogue at UPD," on June 3rd. This event, held in partnership with Student Energy at UP Diliman and The Electrochemical Society - University of the Philippines Student Chapter , was a resounding success. Key Discussions and Highlights: Energy Transition: Co-convenor Dr. Joey Ocon , Head of the Laboratory of Electrochemical Engineering at UPD, discussed the Philippine Energy Transition through the SDG 7 lens. He used the "unfortunate tetrahedron" framework to illustrate the variability of energy sources in terms of affordability, sustainability, reliability, and modernity. Affordable Electricity: CERP co-convenor Atty. Noel Baga emphasized the need to prioritize developing indigenous energy sources, provide energy subsidies, and allow foreign participation in the energy sector to reduce high electricity costs. Importance of Communication and Engagement: Global Effort Against Climate Change: Building on Dr. Ocon's observations, CERP underscores the critical importance of every nation, regardless of size, contributing to the global effort to combat climate change. Dr. Ocon noted that while the Philippines' emissions might be minimal overall, proactive steps towards renewable energy set a precedent and demonstrate a commitment to responsible environmental stewardship. Fostering Public Opinion: Atty. Baga highlighted the necessity of communication in fostering informed public opinion and policy decision-making. Engaging a wider audience helps elevate the discourse around crucial energy policies, ensuring that diverse perspectives contribute to shaping a sustainable energy future. CERP's Commitment: Fair and Transparent Energy Pricing: CERP is dedicated to advocating for fair and transparent energy pricing mechanisms that protect all consumers, especially the most vulnerable. The mission goes beyond research, striving to lead in policy advocacy that promotes energy affordability and sustainability. Community Engagement: By facilitating informed discussions like the #WattsUP roadshow, CERP aims to connect the public with policymakers, fostering laws that are both innovative and beneficial for society.

Congratulations to Michael Castro, Roy Domalanta, Prof. Julie Anne Del Rosario Paraggua, and Prof. Joey D. Ocon! The team is proud to announce the publication of their latest paper, "Energy, power, and cost optimization of a sodium-ion battery pack via a combined physics-based and cost modeling approach," in the prestigious Journal of Energy Storage! Beginning their work in early 2022, the team dedicated over a year to this groundbreaking study. The journey included overcoming the challenge of transitioning from the initial journal due to review delays. Their perseverance and dedication have now been rewarded with a peer-reviewed and accepted paper! Innovative Methodology The study presents a novel method that integrates physics-based models with cost models to optimize the energy, power, and cost of sodium-ion (Na-ion) battery packs. This comprehensive approach provides a detailed analysis and significant improvements in Na-ion batteries, positioning them against the more commercially mature lithium-ion (Li-ion) batteries. The optimized Na-ion batteries were benchmarked against Li-ion batteries, revealing potential areas for future enhancement through advancements in materials science and economies of scale. This benchmarking process is crucial for identifying the strengths and weaknesses of Na-ion technology, paving the way for its commercial viability. This research represents a major advancement in the quest for sustainable and efficient battery technologies. The insights gained from this study could lead to more cost-effective and powerful energy storage solutions, contributing to a greener and more sustainable future. Highlights • Optimized electrode thicknesses and porosities for energy, power, and low-cost cells • Energy and low-cost cells have thick and low-porosity electrodes, unlike power cells. • Performance and cost tradeoffs exist between energy and low-cost versus power cells. • Low potential anode materials are needed to raise energy density of Na-ion batteries. •Increased production of Na-ion batteries is expected to drive down material costs. For more details, you can read the full paper in the Journal of Energy Storage: https://doi.org/10.1016/j.est.2024.112414 Stay tuned for more updates on cutting-edge research and advancements in battery technology!
