Key Terms

solid-state lithium-metal battery technical

A solid-state lithium-metal battery is a rechargeable battery that replaces the flammable liquid inside conventional lithium-ion cells with a solid material and uses lithium metal for the charge-storing electrode. That change can pack more energy into the same size, charge faster and reduce fire risk, so it matters to investors because it can lower costs, improve product performance (for electric vehicles and devices) and reshape supply chains if it becomes commercially viable.

oem technical

OEM stands for Original Equipment Manufacturer, which is a company that produces parts or components used in the final products made by other companies. For investors, understanding OEMs is important because their performance can impact the supply chain and overall success of major industries, especially those relying on specialized parts. Think of OEMs as the suppliers that provide the building blocks for larger products, like the engine parts for a car.

pilot production technical

Pilot production is a small-scale manufacturing run that tests whether a product can be reliably made, assembled and packaged using the intended processes and equipment before committing to full-scale production. Think of it as a dress rehearsal that reveals practical problems, cost estimates and quality consistency; successful pilot production reduces the risk of costly delays or redesigns and signals to investors that a product is closer to generating stable revenue.

cobra process technical

The COBRA process is the federal program that lets people temporarily keep their employer-sponsored health insurance after leaving a job or having hours cut, typically by paying the full premium plus a small administrative fee — like continuing the same car insurance after you no longer drive the car. Investors care because COBRA creates predictable short-term benefit costs and administrative obligations tied to layoffs or turnover, which can affect cash flow, severance planning and the financial impact of workforce changes.

gigawatt-hour technical

A gigawatt-hour is a measure of electrical energy equal to one billion watt-hours (or 1,000 megawatt-hours); it describes how much electricity is produced, stored or consumed over time rather than how fast. Investors care because it translates capacity into revenue and value — for example, a project rated in gigawatt-hours can be thought of like a battery or power plant that can run a million homes for an hour, which helps compare size, output and potential earnings across assets.

automation technical

Automation is the use of technology to perform tasks with minimal human intervention, often replacing manual work with machines or software. It matters to investors because it can increase efficiency, reduce costs, and enable faster decision-making, potentially leading to higher profits and competitive advantages for businesses.

SAN JOSE, Calif.--(BUSINESS WIRE)-- QuantumScape Corporation (NASDAQ: QS), a global leader in next-generation solid-state lithium-metal battery technology, today celebrated the inauguration of its newly installed Eagle Line at its facility in San Jose. The event was attended by automotive OEM customers, QS ecosystem partners and government officials, and included a showcase tour of the Eagle Line.

The Eagle Line is a suite of equipment, materials and highly automated processes, forming the blueprint for production of QS technology. It incorporates QS’s groundbreaking Cobra process, a unique and highly scalable method for producing the proprietary QS separator.

Upon ramp-up, the Eagle Line will produce QS battery cells to support customer sampling and testing, technology demonstrations, and product integration efforts. It is also intended to demonstrate scalable production of QS technology to enable licensing partners to manufacture at gigawatt-hour scale in their own facilities. In addition, the Eagle Line will serve as a platform to develop and test further technology and process improvements at meaningful scale, enabling QS’s advanced development efforts.

“We’re proud to show the Eagle Line to the world for the first time,” said Dr. Siva Sivaram, president and CEO of QS. “The Eagle Line is a powerful platform to demonstrate scalable production of our solid-state technology and serve customer demand for better batteries. This is the next major step in the commercialization of our technology.”

“The Eagle Line is a real technical achievement on the part of our team,” said Dr. Luca Fasoli, COO of QS. “After deploying the Cobra process, we rapidly moved to scale up our cell build process to increase output, scalability, automation and quality. I’m proud of the intense effort that went into making the Eagle Line a reality.”

Forward-Looking Statements

Certain information in this press release may be considered “forward-looking statements,” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, including, without limitation, statements regarding the development, commercialization, and high-volume scale-up of QS’s battery technology, the anticipated benefits from successful installation and operation of production equipment for the Eagle line, including the implementation of the Cobra process; the anticipated ramp-up of production to support customer sampling, testing, and product integration; the ability of the Eagle Line to serve as a blueprint for scale manufacturing by licensing partners, and the potential impacts of QS’s technology for electric vehicles and other applications, among others. These forward-looking statements are based on management’s current expectations, assumptions, hopes, beliefs, intentions and strategies regarding future events and are based on currently available information as to the outcome and timing of future events. Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely upon forward-looking statements as predictions of future events. The events and circumstances reflected in the forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements due to various risks, including the successful development and commercialization of our solid-state battery technology, achieving technical and financial milestones, building out of high-volume processes and otherwise scaling production, achieving the performance, quality, consistency, reliability, safety, cost and throughput required for commercial production and sale, changes in economic and financial conditions, market demand for EVs, retaining key personnel, competition, regulatory changes, broader economic conditions, and other factors, including those discussed in the section titled “Risk Factors” in our Annual Report and Quarterly Reports and other documents filed with the Securities and Exchange Commission from time to time. Except as otherwise required by applicable law, the company disclaims any duty to update any forward-looking statements.
