The OPINCHARGE project

OPerando analyses and modelling of INterface dynamics and CHARGE transport in lithium-
ion batteries – OPINCHARGE project is an ambitious research initiative focused on advancing the understanding and optimization of lithium-ion batteries (LIBs). They are widely used in various applications such as electric vehicles and portable electronics. The project brings together a consortium of leading research institutions and experts in the field of battery technology.

Main objective

The main objective of OPINCHARGE is to investigate the fundamental processes and degradation mechanisms that occur at the interfaces within LIBs. These interfaces, where active materials, electrolytes, and other components meet, play a crucial role in the performance and lifespan of the batteries. By gaining a deeper understanding of the interfacial phenomena, the project aims to improve the design and functionality of LIBs, leading to safer, more efficient, and longer-lasting battery systems.

To achieve its goals, OPINCHARGE employs a multidisciplinary approach, combining experimental techniques, advanced characterization methods, and computational modeling. The project focuses on three key areas of research:

Interface Dynamics and Evolution

OPINCHARGE investigates the dynamic behavior and evolution of interfaces during battery cycling. By using advanced microscopy and spectroscopy techniques, researchers can observe and analyze the chemical and structural changes that occur at the interfaces, providing insights into the formation and growth of key layers such as the solid-electrolyte interphase (SEI).

Charge Transport Characterization

The project aims to characterize the charge transport properties of active materials in LIBs. Through innovative techniques such as single particle measurements and segmented cell designs, researchers can directly probe and analyze the intrinsic properties of the active materials. It will enabling a better understanding of their electrochemical performance and optimizing their design for improved battery performance.

Isotopes-based Interfacial Characterization

OPINCHARGE utilizes isotopic labeling techniques to study the origins of degradation pathways and interfacial reactions within LIBs. By selectively enriching specific isotopes within the battery components, researchers can track and analyze the chemical and electrochemical processes occurring at the interfaces. This approach provides valuable insights into the degradation mechanisms. Moreover, it helps in the development of more stable and long-lasting battery materials.

project aims

By combining these research efforts, the OPINCHARGE project aims to provide a holistic understanding of LIB interfaces, from atomic and nanoscale interactions to mesoscale transport phenomena. The insights gained from this research will enable the development of innovative battery designs and materials, leading to safer, higher-performing, and more sustainable lithium-ion batteries for a wide range of applications.

Ultimately, the OPINCHARGE project strives to contribute to the advancement of battery technology, supporting the transition towards a greener and more energy-efficient future.
