Leoben researchers improve lifetime of lithium-ion batteries

A significant progress in battery research was recently achieved by the research team of the Material Center Leoben (MCL) and the Montan University Leoben. The scientists have gained decisive knowledge of the mechanisms, which are responsible for the loss of capacity of lithium-ion batteries. This discovery could potentially extend the lifespan of such batteries and thus enable revolutionary improvement in energy storage.

The team used modern materials and technologies to address the challenges in the field of lithium-ion batteries. With increasing electrification in society, the need for powerful and durable energy storage grows. This research could help to optimize future generations of lithium-ion batteries by promoting both the energy density and cycle stability.

causes of the loss of capacity

The Leoben team has found out which complex relationships influence the loss of capacity of lithium-ion batteries (LIBS) through the use of advanced imaging methods and artificial intelligence. These findings are crucial because they enable understanding at the nuclear level of material behavior during the loading and unloading processes. Above all, it was found that damage caused by these processes can lead to phase transitions within the silicon anodes that have unexpected positive effects on the battery life.

A central result of this research is that these phase transitions can actually help prevent the formation of breaks in the silicon particles. This could noticeably stabilize the long -term performance of the batteries and slow down the overall failure of the devices.

perspectives for the future

Research work shows promising approaches to improve the stability of batteries with high energy density. "We believe that innovative designs of the silicon material architecture will revolutionize energy storage applications," said Ronald Brunner, one of the leading researchers. This progress could be fundamental to the development of the next Generation of silicon-ion batteries that could outperform the performance and lifespan of the current battery renovations.

The complete research results were recently published in the renowned journal communications materials , which belongs to the nature portfolio. Further information and details on the research results can be found on www.5min.at .
