In the OPINCHARGE Scientific Publications series, we highlight research that deepens the understanding of battery materials and their performance. This study focuses on a critical but often overlooked aspect of battery design — the role of geometry and mechanics in silicon anodes.This study explores a novel electrochemical approach to remove hydrofluoric acid (HF) impurities from…

In the OPINCHARGE Scientific Publications series, we highlight research that advances our understanding of battery materials, interfaces and degradation processes. This study investigates how ultrathin metal interlayers can control lithium deposition, addressing one of the key challenges facing anode-free solid-state batteries.

In the OPINCHARGE Scientific Publications series, we highlight research that advances our understanding of battery behaviour, performance and safety. This publication explores an important diagnostic tool for lithium-ion batteries — reference electrodes, which allow researchers to look beyond the overall battery voltage and investigate what is happening at individual electrodes.

In the OPINCHARGE Scientific Publications series, we highlight the publication “Advanced methods for characterizing battery interfaces: Towards a comprehensive understanding of interfacial evolution in modern batteries”.

The publication “X-ray Coulomb Counting to Understand Electrochemical Systems” introduces the concept of X-ray Coulomb Counting – an approach that uses X-ray techniques to determine how much electrical charge is associated with individual reactions taking place inside an electrochemical system.

In the OPINCHARGE Scientific Publications series, we highlight research that advances the methods used to understand materials and interfaces at increasingly small scales. This study explores how X-ray nanobeams can be used to analyse micrometre-sized surface areas, opening new possibilities for highly localised material characterisation.

In the OPINCHARGE Scientific Publications series, we highlight research that deepens our understanding of battery materials and the processes that determine their performance and lifetime. This study investigates a major challenge for high-capacity silicon-based anodes — how lithium becomes trapped during cycling and how electrolyte chemistry can help prevent it.

In the OPINCHARGE Scientific Publications series, we highlight research that advances our understanding of materials, interfaces and processes relevant to next-generation energy technologies. This publication presents a new way to visualise how lithium moves inside a solid-state battery while the battery is actually operating.

The latest edition of the OPINCHARGE Newsletter (#5) presents recent progress across the project, with a strong focus on Open Science, research dissemination and collaboration within the European battery community.
