Workshop event
The global transition toward carbon neutrality requires transformative advances in energy storage and electrochemical technologies. The ACSSI-19 conference will bring together leading scientists, engineers, and emerging researchers to share the latest developments in solid-state ionics, electrochemical processes, and next-generation battery technologies. The meeting provides a platform for discussing scientific breakthroughs and fostering collaborations that support sustainable energy systems and accelerate innovation across the energy and materials sectors.
Workshop Overview
ACSSI-19 brings together leading scientists and engineers in solid-state ionics, electrochemical processes, and battery technologies. Hosted by Chulalongkorn University, the four-day conference features parallel workshops, plenary and oral sessions, poster presentations with 1-minute pitches, and a closing Conference Highlights session with awards. The program is designed to foster scientific exchange, mentoring, and collaboration between academia and industry, complemented by an exhibition and a Tech Theater track. The meeting is expected to welcome around 400 participants, including at least 100 international delegates.
