币界网报道：QuantumScape (QS) shares surged over 40% in premarket trading following Volkswagen's announcement of successful endurance tests for its solid-state batteries. The German automaker's PowerCo battery division confirmed the prototype cells exceeded industry targets by retaining over 95% capacity after 1,000 charging cycles, equivalent to 500,000 kilometers of range. This breakthrough validates QuantumScape's technology as potentially solving key electric vehicle challenges - faster charging, longer lifespan, and greater range. Volkswagen Group CEO Oliver Blume called the results "encouraging," while QuantumScape CEO Jagdeep Singh highlighted the achievement of automotive-grade performance targets. The test results mark significant progress toward commercial production, with Volkswagen planning to produce solid-state batteries at its Salzgitter plant by 2025. The news boosted investor confidence in QuantumScape's potential to revolutionize EV battery technology despite previous skepticism about commercialization timelines.
