Independent Technology Assessment — Due Diligence Report

Report Details

Executive Summary

QuantumCore Materials represents a compelling deep tech investment opportunity in the solid-state battery space. The company's patent-pending QCMatrix solid-electrolyte technology addresses the critical dendrite suppression problem that has stalled commercialization across the industry. Our independent assessment — including a site visit to the company's Austin lab, review of internal test data, and consultation with three external materials science experts — indicates the technology is genuine and potentially best-in-class among pre-commercial solid-state approaches.

At the reported $45M pre-money Series B valuation, we believe the company is significantly undervalued relative to its technology quality, IP position, and the strategic interest it has attracted. Our fair value assessment of $180–220M is based on comparable transactions, technology benchmarking, and probability-weighted licensing scenarios.

Technical Assessment

We engaged Dr. Robert Keller, Professor of Materials Science at MIT, and Dr. Lisa Yamamoto, formerly head of solid-state R&D at Samsung SDI, to conduct independent reviews of QuantumCore's technical claims. Both were provided access to raw test data under NDA. Key findings:

• Ionic conductivity (4.2 mS/cm at 25°C): Both reviewers confirmed this result is consistent with the data presented and would represent the highest reported room-temperature conductivity for a solid electrolyte with demonstrated dendrite suppression. Current published benchmarks are 1–2 mS/cm for ceramic sulfides and 0.1–0.5 mS/cm for polymer electrolytes.
• Cycle stability (500+ cycles at 0.5C, <8% capacity fade): Dr. Yamamoto noted this performance is "at or above the best academic results I've seen, though I'd want to see it replicated by a third-party lab at larger cell format." Dr. Keller agreed the data is plausible.
• Manufacturing approach: The roll-to-roll coating process described in the provisional patent uses existing lithium-ion manufacturing equipment, which both reviewers flagged as a significant advantage — it reduces capital expenditure risk vs. competitors requiring novel manufacturing infrastructure.

Dr. Keller's written assessment: "The claims in QuantumCore's provisional patent application are scientifically plausible and, if validated at scale, would represent a meaningful advancement over the current state of the art. The roll-to-roll manufacturing approach is particularly noteworthy for its commercial practicality."

Dr. Yamamoto's written assessment: "I was initially skeptical of the conductivity claims, but the raw data I reviewed is internally consistent and shows clear reproducibility across multiple batches. I'd rate the probability of these results holding up in independent testing at around 70–75%."

Lab Visit Summary

Our team visited QuantumCore's Austin facility on March 14, 2026. Observations:

• Clean room and wet lab facilities are well-equipped for a company at this stage (~3,500 sq ft lab space)
• We observed live conductivity testing on two QCMatrix samples prepared during our visit — results were consistent with the dataset provided
• The team of 12 R&D staff includes 4 PhDs in materials science/electrochemistry, all with relevant prior industry experience
• The pilot-scale roll-to-roll coater (installed January 2026) was operational and producing sample electrolyte sheets

Competitive Landscape

If QuantumCore's conductivity results are confirmed by Argonne, the company would hold the best-in-class performance benchmark in the solid-state battery startup space. At $45M pre-money, the valuation discount to peers is extreme — even with the appropriate risk premium for earlier stage and private status.

Risk Factors

• Technology risk: Internal lab results may not replicate at commercial scale or in independent testing
• IP risk: Provisional patent has not been examined; final grant is not assured
• Financing risk: Company will need Series B to close to fund pilot production; cash runway ~14 months at current burn
• Team risk: Small team; loss of key technical personnel could delay milestones
• Competitive risk: Well-capitalized incumbents (Toyota, Samsung SDI, CATL) have significant solid-state battery R&D programs
• Liquidity risk: Private company shares are illiquid; exit timeline is uncertain (3–7 year horizon typical)
