QuantumScape (QS) Stock SKYROCKETS After Groundbreaking Solid-State Battery Deals
QuantumScape is a Silicon Valley startup developing solid-state lithium-metal batteries for electric vehicles. Unlike conventional Li-ion packs with liquid electrolytes, QS’s batteries use a solid ceramic separator and a pure lithium-metal anode. This design boosts energy density and charging speed while reducing fire riskquantumscape.commarketscreener.com. Investors bet that QS’s tech could give EVs longer range and simpler packaging. In late September and early October, QS delivered on that promise with major announcements. On Sept. 30 it revealed a joint agreement with Corning, Inc. to co-develop manufacturing for QS’s ceramic separatorsquantumscape.com. Corning’s ceramics expertise will help QS scale up “high-volume production” of these separators for commercial batteriesquantumscape.com. QS CEO Siva Sivaram praised the partnership, noting “Corning’s world-class capabilities in ceramics manufacturing make it an ideal addition to the QS technology ecosystem”quantumscape.com. Similarly, on Oct. 7 QS and Murata Manufacturing formalized a joint-development deal for QS’s ceramic separatorsmarketscreener.com. Murata has long-discussed collaboration since early 2025, and now will apply its ceramics material and firing expertise to scale production of QS’s separatorsmarketscreener.com. Murata’s president Norio Nakajima said the companies will move QS’s technology “to a new stage… leveraging [Murata’s] strengths in ceramics technology”marketscreener.com, and Sivaram added that “partnership with Murata is an important part
