Europe's battery supply chain is being built in real time ' but delivering it at scale is proving complex. The focus now is on how OEMs and battery manufacturers are working together to secure supply, manage risk and execute on ambitious timelines. This session explores how these partnerships are operating in practice ' where alignment is working, where challenges remain, and what this means for the next phase of Europe's battery build-out. ' How OEMs and battery manufacturers are aligning on capacity, timelines and technology ' What localisation looks like in practice across both sides of the partnership ' Managing cost, risk and supply chain complexity ' How EV demand is shaping battery production decisions ' What has worked ' and what hasn't ' in building these partnerships ' What this means for the next phase of Europe's battery expansion
