​Graphene mesosponges reveal hidden weak links in batteries 

Researchers from Tohoku University, Manchester Metropolitan University, Gunma University, University of Cambridge and Kyushu Synchrotron Light Research Center have made progress in the quest for longer-lasting lithium–oxygen (Li‑O₂) batteries – an energy storage technology with the potential to power future electric vehicles and renewable energy grids.

At the heart of their discovery is a high-purity 13C-labeled graphene mesosponge (13C-GMS) – a unique carbon material featuring a porous, sponge-like structure. This advanced graphene framework allowed the team to precisely trace and distinguish how different parts of the battery degrade over time.
