【TJU 130】Long Peng: Advancing Innovation in Energy Materials

In a story that exemplifies the spirit of scientific exploration and technological progress, Long Peng, an outstanding alumnus of the School of Materials Science and Engineering at Tianjin University, has emerged as a leading figure in the development of next-generation energy materials. Currently serving as Vice General Manager and Chief Engineer at Hunan Jinbo Hydrogen Energy Technology Co., Ltd., Long oversees research and development of carbon paper, bipolar plates, and hydrogen storage tanks - critical components in hydrogen energy systems.

Long began his doctoral studies in polymer materials at Tianjin University in 2014, under the mentorship of Professor Feng Wei. Early in his Ph.D., he delved into fluorinated carbon compounds, materials known for their exceptional theoretical energy density among primary batteries. Motivated by the challenge of pushing the frontiers of energy storage technology, Long and his team spent four years developing a hierarchical porous structure in fluorinated carbon, achieving a record-breaking energy density of 2738 Wh/kg - a major advancement that extended battery life for critical applications such as cardiac pacemakers.

His work has earned multiple national and international patents and reflects a firm belief that “to innovate is not only to meet today’s needs, but to safeguard tomorrow’s development”. This is a principle deeply aligned with Tianjin University’s motto of “Seeking Truth from Facts.”

Following his doctorate, Long continued his research as a postdoctoral fellow at Hunan University, where he developed highly stable catalysts for hydrogen fuel cells using fluorinated carbon as a support material. His exploration into material interfaces at the micro scale opened new pathways for breakthroughs in clean energy technologies.

Since joining Jinbo Hydrogen in 2021, Long has led the development of advanced carbon fiber composites tailored for hydrogen energy systems. His innovations not only address key technical challenges but also contribute to the broader mission of sustainable energy advancement.

In 2025, as Tianjin University marks its 130th anniversary, Long’s story stands as a testament to the university’s enduring commitment to cultivating scientific excellence and fostering a culture of innovation. As he once said: “We are not just engineers. We are builders of national strength, crafting the future in microns.”

Long Peng continues to embody the Tianjin University spirit - grounded in realism, driven by curiosity, and devoted to advancing the frontiers of knowledge. His journey reflects the transformative power of research and perseverance, inspiring future generations to explore, create, and lead.
