Holyvolt × an unnamed cell buyer × a procurement rule: buy the lab first, promise the market in 2027

One of the Buyer Chains series. Each piece follows one chain, the AI company, its customer and sometimes the customer's customer, through five roles in the public record: who states the need, who sets the research direction, who runs the experiments, who validates the result, who decides to keep paying. It records only what the public record states and says who said each thing; a missing step is marked not yet public rather than filled in, and a company's own figure is written as the company's. The timeline at the end stays open: when the chain's next step reaches the public record, it goes on as a new line.

Holyvolt is a battery-materials company headquartered in Stockholm with its lab in San Diego. In 2026 it merged with Wildcat Discovery Technologies, a high-throughput battery-testing lab founded by the chemist Peter G. Schultz and run for 18 years; the company says the platform has run over 225 projects for over 85 customers, nearly a dozen of them Fortune 500 companies including BMW, and holds data on over 500,000 physical cells and over 165 million cycles.[1] On 15 October 2026 it announced $45M from Zone II, CC.VC and a handful of angels, to expand its AI models, lab capacity and team and to take its first material, DRX (a disordered rocksalt cathode with no nickel or cobalt), toward commercial deployment: the company plans to begin commercialising DRX in 2027, starting with defence and then larger mobility markets.[1] What sets this chain apart is the order: it bought the data and the lab first and trained on them afterwards. Its buyer has no name in the public record yet; what has a name is a procurement rule.

What the buyer looks at, concretely

• Battery buyers' acceptance criteria are among the most public in any industry. The US Advanced Battery Consortium (USABC) writes its EV cell targets as numbers: 1,000 DST cycles at 100% fast charge, 15-year calendar life, 300 Wh/kg, $60/kWh at 250,000 units; the test procedures are IEC 62660-1 (performance) and IEC 62619 (industrial cell safety).[3] Defence drone specifications are not public, but they turn on the same four things: cycle life, energy density, safety, cost.
• Holyvolt's own public material carries none of those numbers for DRX: the release says "high energy density" and nickel- and cobalt-free, with no Wh/kg, cycle count or cost.[1]
• So the next thing to look for in this chain is specific: a named cell maker or defence buyer that has tested DRX to its own specification and said what it found.

Not yet public · Any DRX performance figure; a customer; the price paid for Wildcat; whether "begin commercialising" in 2027 means samples, a small batch or volume; the basis of the valuation.

Decision point · The next decision belongs to a cell maker or a defence buyer: whether to test DRX to its own specification. That buyer has no name in the public record yet, and the procurement rule takes effect on 1 October 2027.

The chain's timeline

• 2026Holyvolt merges with Wildcat Discovery Technologies, taking its lab and 18 years of data (company release)[1]
• 2026-03DRX data shown at the International Battery Conference (the record)[2]
• 2026-10$45M raised; DRX to begin commercialisation in 2027, defence first (company release)[1]
• NextA named buyer tests DRX to its specification; DRX's Wh/kg, cycle life and cost made public. Awaiting public data.
• 2027-10-01The procurement rule takes effect: the date the company's own schedule has to meet.
• LaterThe first DRX order.
