Everyone agrees solid-state batteries are coming. What the industry can’t agree on is when they’ll matter – and what has to happen first.

Pilot lines exist and OEM roadmaps point to the late 2020s, but beneath that shared timeline expert opinion diverges: on whether costs can ever match Chinese LFP, how well the safety advantage holds up under real-world fast charging, and whether the real breakthrough is energy density or the way anodeless designs quietly reshape manufacturing.

In this Technology Insight, six leading voices from Roland Berger, QuantumScape, BASF, Fastmarkets and KnowMade map where the technology really stands – and the milestones that will signal the tipping point.
