Carbon for Batteries

Hard and Graphitic Carbon Materials for Li-, Na- and K-Ion Batteries

The team develops hard (non-graphitizable) and graphitic carbon materials with carefully controlled properties — including structure, morphology and surface chemistry — for use as negative electrodes in lithium-, sodium- and potassium-ion batteries. A central research objective is to understand the synthesis–structure–performance relationship in order to design materials with improved electrochemical performance. The team also studies charge storage mechanisms and the interfacial phenomena between carbon electrodes and electrolytes to enhance electrode lifetime and stability.

Research Highlights

• Binder chemistry and electrode processing strategies to improve durability and reduce environmental impact.
• Electrode–electrolyte interfacial phenomena, including solid electrolyte interphase (SEI) formation and its impact on cycling stability.
• Charge storage mechanisms in hard and graphitic carbons for Li-, Na- and K-ion systems.
• Recycling and valorization approaches for carbon-based electrodes, contributing to more sustainable battery technologies.

By linking materials design with electrode engineering and end-of-life considerations, this theme aims to develop high-performance, durable, and more sustainable carbon electrodes for emerging energy storage technologies.
