QuantumScape Announces QS-7 Solid-State Battery Validation by Third-Party Lab (April 8, 2026)**\n- QuantumScape confirmed that its QS-7 solid-state lithium-metal battery passed independent testing at the U.S. Department of Energy’s Argonne National Laboratory. The cell demonstrated 95% capacity retention after 1,200 cycles at 4.5 mA/cm², with a volumetric energy density of 1,150 Wh/L. The results suggest readiness for integration into electric vehicles, with Volkswagen planning prototype testing in 2027.\n- Source: QuantumScape press release, April 8, 2026 – https://www.quantumscape.com/news-releases/news-release-details/quantumscape-announces-third-party-validation-qs-7-solid-state*\n- 2. CATL Launches Sodium-Ion Battery Pack for Electric Buses in Nanning, China (April 10, 2026)**\n\n## Analysis\nContemporary Amperex Technology Co. Limited (CATL) deployed its first commercial vehicle fleet using its second-generation sodium-ion batteries. The 280 Ah Sinopoly NaCell powers 50 electric buses in Nanning, achieving 400 km range per charge and charging from 10% to 80% in 15 minutes at -20°C. CATL stated mass production of sodium-ion packs for light EVs will begin in Q3 2026.\n\n*Source: CATL official website, April 10, 2026 – https://www.catl.com/news/sinopoly-sodium-ion-bus-deployment*\n\n**3.
