A coordinated investigation by battery researchers and 20+ independent experts found that Donut Lab's flagship product is conventional lithium-ion technology with misleading marketing—a credibility failure that exposes venture capital pressure to claim breakthroughs faster than they can deliver. Solid-state batteries are a genuine industry goal with real commercial stakes. False claims distort investment signals, waste capital, and create skepticism that slows legitimate R&D. The expose shows that peer review in deep tech still depends on specialists willing to publicly challenge venture-backed claims.
