QuantumScape 发布 Osprey 全固态电池开放平台：硫化物正极电芯在 1 个大气压下循环 1000 次、10% 至 80% 充电 5 分钟
美国加利福尼亚州圣何塞市 — QuantumScape 公司 2026 年 11 月 11 日经 GlobeNewswire 宣布推出 Osprey，这是其下一代全固态电池开放平台。公司表示，Osprey 电芯给出了全球首份公开数据，证明硫化物基正极能在仅 1 个大气压下循环 1000 次，公司称这是车用固态电池所必需、此前无人能及的能力。
结构方面，Osprey 把 QuantumScape 自有的陶瓷隔膜和无负极锂金属设计与固体正极结合，构成全固态电芯。Osprey 建立在公司的 QSE 平台之上，为现有客户打开新的授权与联合开发选项，并把供给扩展到硫化物基全固态电池的开发者。
公司公布的早期测试数据包括四项：循环寿命为 1000 次完整充放电后容量保持约 80%；快充为 10% 充至 80% 用时 5 分钟；工作压力仅需 1 个大气压；低温性能可工作至零下 20 摄氏度以下。公司称，全固态正极配合自有陶瓷隔膜还带来更快充电、更宽工作温度范围，以及最高约 1100 瓦时每升的预估能量密度。更多测试结果与条件载于公司新发布的白皮书。
公司总裁兼首席执行官 Siva Sivaram 博士在发布中表示，Osprey 是多年研发的成果，公司目标是使其成为固态电池开发的主导平台。公司表示，已在与汽车行业伙伴用 Osprey 平台开展开发，基于 QSE 平台的电芯目前已在向客户出货。本稿数字均以 QuantumScape 11 月 11 日发布正文为准。
QuantumScape Unveils Osprey, an Open All-Solid-State Battery Platform: Sulfide Cathode Cells Cycle 1,000 Times at One Atmosphere, Charging from 10 Percent to 80 Percent in Five Minutes
San Jose, California — QuantumScape Corporation announced Osprey, its next-generation open platform for all-solid-state batteries, via GlobeNewswire on November 11, 2026. The company said Osprey cells have delivered the first public data demonstrating a sulfide-based cathode cycling 1,000 times under just one atmosphere of pressure, a capability it called unmatched and necessary for automotive solid-state batteries.
Osprey pairs the proprietary QS ceramic separator and anode-free lithium-metal design with a solid cathode, creating an all-solid-state cell. Osprey builds on the company QSE platform and opens new licensing and co-development options for current QS customers, while expanding the offering to developers of sulfide-based all-solid-state batteries.
In early testing, the company reported four results: a cycle life of 1,000 full charge cycles with about 80 percent capacity retention; fast charging from 10 percent to 80 percent in five minutes; an operating requirement of only one atmosphere of pressure; and operation to below minus 20 degrees Celsius. The company said the all-solid cathode, paired with its ceramic separator, also enables projected energy densities up to about 1,100 watt-hours per liter. More information, including test results and conditions, is in a new white paper.
Dr. Siva Sivaram, president and CEO of QS, was quoted in the release. The company said it is already working with partners across the automotive industry on development using the Osprey platform, and that cells based on the QSE platform are shipping to customers today. All figures follow the text of the QuantumScape release dated November 11, 2026.
