Asst. Prof. Castro Publishes New Breakthrough Research on Sodium-Ion Battery Optimization
Mecaelah Palaganas • July 6, 2024
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.

LEE research staff and graduate students participated in an in-house training and workshop on the Python for Power Systems Analysis (PyPSA) toolbox on October 9 and 23, 2024 . The sessions were led by Arizeo Salac (SRS 1, ElectriPHI), who returned from a six-month research sandwich program at the Reiner Lemoine Institute in Berlin, Germany , where he focused on data-driven decision-making and energy systems modeling. The training included a detailed discussion on energy systems modeling, with key topics such as data sources and the representation of energy systems using both conventional and renewable technologies. Participants received hands-on assistance with the software setup and installation, followed by simulation activities that showcased PyPSA’s capabilities in energy and power systems analysis. Mr. Salac also presented his baseline model of the Philippine energy system, which can be utilized for energy transition scenario planning. The event aimed to enhance participants' proficiency with open-source modeling tools, share best practices in modeling, and support their research in energy systems. Article by: Sophia Lunor
Prof. Joey D. Ocon, Dr. Julie Anne D.R. Paraggua, Dr. Lawrence Limjuco, and Giancarlo Sanglay were among the Filipino delegates at the 2nd ASEAN Battery Technology Conference , held from August 21 to 23, 2024 , at the Shangri-La Rasa Sentosa in Singapore. Themed "Powering ASEAN: Innovating the Future of Battery," the event was co-organized by key ASEAN associations from Singapore, Thailand, Indonesia, Malaysia, and the Philippines. They were accompanied by LEE member and graduate student, Giancarlo Sanglay and NextGen Project Chief Technical Specialist, Dr. Lawrence Limjuco, of the Advanced Batteries Center. The conference aimed to foster connections among researchers, engineers, and industry stakeholders within the battery and electric vehicle (EV) sectors. It provided a platform for knowledge exchange, technical discussions, and potential collaborations. Key topics included the development of the Battery and EV Roadmap for Southeast Asia, as well as government policies and regulations surrounding battery and energy storage systems (ESS) applications. Industry leaders and academic experts also addressed technological advancements in battery materials, financial support for innovations, and strategies for managing the end-of-life value chain of batteries. Prof. Ocon, who also serves as Co-Founder of Nascent Batteries, played an active role in the event by moderating a panel discussion on advancing ESS technologies in Asia. The panel featured representatives from prominent organizations, including EDP Renewables APAC, Green Tenaga Pte Ltd, and the Electricity Generating Authority of Thailand. This collaborative event underscored the region's commitment to advancing sustainable energy solutions and highlighted the critical role of ASEAN countries in driving innovation within the battery and EV industries.

The Laboratory of Electrochemical Engineering (LEE) held a despedida party to bid farewell to two of its active members — Ms. Rosela Lazaro and Asst. Prof. Michael Castro — as they embark on a new chapter of their academic journey. The LEE members, along with their laboratory head, Prof. Joey D. Ocon, celebrated through a friendly competition at the Ever Gotesco Bowling Alley, Commonwealth Avenue last August 19, 2024. This also fostered camaraderie and strengthened the bond and friendship between the lab members. Ms. Lazaro will be studying MS in Environmental Science and Engineering at Gwangju Institute of Science and Technology, South Korea. Meanwhile, Asst. Prof. Castro will be pursuing a doctorate degree in Nuclear Engineering and Management at the University of Tokyo, Japan. He will be returning to UP Diliman to tend to his duties at the Department of Chemical Engineering. Indeed, ‘goodbyes’ are not the end. It marks a beginning of a new ‘hello’, a step closer to making dreams come true. To Sir Michael, ganbatte! To Sela, hwaiting! We are all rooting for you both! Article by: Lora Monique Sapanta
