Stockholm battery-materials startup Holyvolt announced $45 million in financing on October 15, 2026, to expand its artificial-intelligence models, scientific staff and automated laboratory. Fortune reported that the round was all equity and valued the company at $245 million, citing a person familiar with the deal; Holyvolt has not publicly confirmed that valuation.
Zone II and CC.VC are named backers, alongside finance-sector angel investors. Fortune also listed Fifth Wall in connection with the round. Holyvolt’s first named material is a nickel- and cobalt-free disordered-rocksalt cathode called DRX, which it is developing toward commercialization.

What Holyvolt’s $45 million financing covers
The financing is intended to increase the speed and scope of Holyvolt’s battery-materials discovery work rather than fund a disclosed production expansion. The company says the money will support three areas: AI models, its scientific team and an automated high-throughput laboratory.
| Item | What is publicly reported |

How Holyvolt’s AI battery platform works
Holyvolt describes its system as a “Discovery Engine” that links machine-learning predictions to physical laboratory work. That distinction matters: the company is not presenting an AI-only screening service. Its stated approach repeatedly proposes materials, makes and tests them, then feeds the experimental results back into the models.
- Use historical data: Holyvolt says the system draws on approximately 18 years of proprietary battery data.
- Predict candidates: AI models identify material compositions or structures that may be worth testing.
- Manufacture and test physically: The automated laboratory produces candidate materials and measures their behavior.
- Update the next cycle: Results from those experiments are used to improve subsequent predictions and experiments.
Automating this loop is intended to reduce the time between a theoretical candidate and a measured result. The public description does not state the laboratory’s sample rate, cell format, yield, model accuracy or cost per experiment.
What DRX cathode material is
DRX stands for disordered rocksalt, a cathode-material family in which the arrangement of atoms differs from the ordered structures used in many conventional cathodes. Holyvolt describes its DRX material as containing neither nickel nor cobalt.
The chemistry target addresses both material cost and supply-chain exposure. Holyvolt argues that reducing reliance on nickel and cobalt could help battery makers avoid parts of the cathode-material supply chain in which China has a dominant position. DRX is the first material the company has named as moving toward commercialization, but that wording describes a development objective, not a product already available to cell manufacturers.

Why the company says the supply chain must change
“We will not be able to out-China China on the battlefield that China has defined,” COO Steven Prast said. The comment captures Holyvolt’s strategic premise: competing only on the established large-scale manufacturing routes may leave Western battery companies dependent on suppliers and processing capacity concentrated in China.
Holyvolt’s proposed alternative is to compete on discovery and chemistry selection first, then develop materials that can be made through an industrially practical process. Whether that strategy succeeds will depend on more than a promising formulation: cathode materials must meet performance, safety, lifetime, cost and manufacturing requirements at cell scale.
How to assess Holyvolt against other battery-materials startups
| Comparison question | What Holyvolt says or has disclosed | What remains unestablished |
|---|---|---|
| AI approach | AI predictions are paired with automated physical manufacture and testing. | No public benchmark for prediction accuracy or cycle time. |
| Chemistry target | DRX is described as nickel- and cobalt-free. | Detailed composition and independently verified cell results are not publicly stated. |
| Data and throughput | Approximately 18 years of proprietary battery data and a high-throughput laboratory. | No disclosed dataset size, experiment volume or laboratory utilization. |
| Path to manufacturable cells | The Discovery Engine is intended to connect discovery with physical testing. | Manufacturing partners, pilot-line milestones and qualification procedures are not publicly stated. |
| Industrial backing | Zone II, CC.VC, finance-sector angels and Fifth Wall have been associated with the financing. | The reports do not identify a cell-maker qualification agreement. |
| Commercial evidence | DRX is moving toward commercialization. | No verified public revenue, customer shipment, commercial production or customer-qualification metric is reported. |
What the funding does—and does not—prove
The $45 million round gives Holyvolt resources to expand its models, hire scientists and run more automated experiments. It also signals that specialist and financial investors are willing to fund an approach combining computation with laboratory work.

The public material available with the financing announcement does not provide independently verified figures for energy density, cycle life, safety, manufacturing cost, pilot output or customer testing. Those are the milestones to watch as Holyvolt moves from discovery toward qualification.

Bottom line
Holyvolt is building an AI-assisted battery-materials discovery operation in Stockholm, backed by a $45 million equity financing announced in October 2026. Its distinctive claim is the closed loop between roughly 18 years of data, AI predictions and automated physical experiments. DRX, a nickel- and cobalt-free disordered-rocksalt cathode, is the first named target. Fortune’s $245 million valuation is a reported deal figure rather than a valuation Holyvolt has confirmed, and the company has not yet disclosed the operating or customer evidence needed to judge commercial readiness.
