QuantumScape’s Path to Commercialization
QuantumScape Corporation (NYSE: QS) recently reached a major manufacturing milestone, triggering a 35% rise in its stock during after-hours trading. The solid-state battery innovator has successfully incorporated its advanced Cobra separator process into baseline cell production—a critical step toward achieving commercial viability.
The Cobra platform represents a significant upgrade over QuantumScape’s earlier Raptor process. It enables approximately 25 times faster heat treatment and occupies considerably less space. This ceramic solid-state separator production technique is essential for large-scale production, as it greatly enhances scalability and cost-effectiveness. QuantumScape expects to realize further improvements in production efficiency with future iterations of the Cobra process.
Separately, for those seeking potential upside with less volatility than individual stocks, consider the High Quality portfolio, which has outperformed the S&P and delivered returns exceeding 91% since inception. Also, see – Should You Buy RKLB Stock At $33?

Commercial Path Forward
QuantumScape’s key commercialization partner is PowerCo, Volkswagen Group’s battery unit. Their non-exclusive licensing agreement, announced last year, permits PowerCo to produce up to 40 gigawatt-hours (GWh) annually using QuantumScape’s technology, with an option to scale up to 80 GWh. This capacity could support battery production for around one million vehicles each year and replaces the previous joint venture model, providing a more direct path to large-scale deployment.
The technology has already demonstrated encouraging outcomes. In early 2024, PowerCo confirmed that QuantumScape’s solid-state cells significantly exceeded performance benchmarks in A-sample testing, achieving more than 1,000 charging cycles—equivalent to over 500,000 kilometers for EVs with a 500-600 kilometer WLTP range.
Financial Position and Market Outlook
At present, QuantumScape remains a pre-revenue company and posted an operating loss of $517 million over the past twelve months, in line with its developmental phase. However, the successful integration of Cobra technology enables the company to produce higher-volume samples of its inaugural commercial product, QSE-5.
Solid-state batteries offer several advantages over traditional lithium-ion cells, including extended driving range, faster charging capabilities, and improved safety. As QuantumScape moves from R&D to production-readiness, the Cobra breakthrough affirms its manufacturing strength and commercial promise.
With this technical progress, the company’s ability to meet its 2025 production goals will be pivotal to tapping into the rising demand for advanced EV battery solutions.
Investment Risks
Investing in a pre-revenue company like QuantumScape comes with inherent risks, including those tied to manufacturing, scaling, and financial sustainability. The solid-state battery landscape is highly competitive, with well-funded rivals like Toyota, Samsung SDI, LG Chem, and Solid Power already possessing extensive resources. Companies such as BYD are even in the early stages of production and validation, possibly reaching commercial scale ahead of QuantumScape. These competitors also benefit from existing supply chains and infrastructure, giving them a scaling advantage.
Broader economic factors add another layer of risk. For example, during the inflation surge of 2022, QuantumScape’s stock dropped 85% from its peak—far outpacing the S&P 500’s 25% decline. Investors must weigh these risks carefully. In fact, we employ a risk framework in building the Trefis High Quality (HQ) Portfolio, a selection of 30 stocks that has consistently outperformed the S&P 500 over the past four years. Why? These HQ stocks tend to deliver superior returns with lower volatility compared to the broader market—as shown by the HQ Portfolio performance metrics.
