Evermore is converting an operating pilot, two distinct silicon-anode cell programs and a semi-solid electrolyte development pathway into a planned 500 MWh commercial facility in Texas.
Cells, materials, independent test records and production-representative batches are available for diligence.
ELVION-X and ELVION-S follow distinct specifications, qualification paths and evidence records.
The ArC Center turns materials work into process settings, batch learning, quality records and manufacturing knowledge.
Texas is planned for 500 MWh per year of commercial production—not another demonstration line.
Advanced systems depend on cells whose performance, qualification and supply cannot be separated.
Defense, aerospace, autonomous systems, robotics and critical infrastructure operate across different envelopes. Dependence on concentrated foreign supply chains adds disruption risk to an already demanding technical problem. The stronger architecture is configurable, qualification-led and built close to the customer.
Evermore advances two cell programs and a semi-solid development pathway. Each claim is presented according to its current evidence status.
Current large-format qualification build: approximately 300 Wh/kg and 788 g measured cell mass.
Current small-format production-design pouch cell incorporates 10% silicon and follows its own qualification path.
ELVION-S testing followed UL 1642 and UN 38.3 protocols. Formal certification is not represented as complete.
Up to 25% silicon and semi-solid integration are platform development objectives—not the current ELVION-X production specification.
Evermore’s market strategy spans defense and commercial systems. Project underwriting requires the customer pipeline to progress from samples and technical evaluation into documented volumes, pricing and credible purchase intent.
Define customer test plans, cell configuration, acceptance criteria and decision dates.
Translate programs into forecast MWh, production start dates and ramp schedules.
Build a dual-use base across defense and non-federal commercial customers.
Demonstrate debt service from commercial operations under base and downside cases.
The ArC Center in the Republic of Korea is the pilot and process-development base. Texas is the planned commercial manufacturing project. The transfer must be engineered and documented with the same discipline as the production line.
Production-representative builds, process settings, quality records, failure analysis and operating knowledge.
Recipes, equipment specifications, control plans, training, traceability and commissioning criteria.
A multi-chemistry, supplier-diversified architecture; alternate sources remain subject to controlled validation.
IP rights, corporate control, critical suppliers, counterparties and technology-transfer governance documented for review.
Performance follows from control of the cell architecture.
Endurance · peak power · temperature · cycle life · safety · geometry
Semi-solid electrolyte · silicon anode system · cathode chemistry · cell architecture
Configured architecture · production-representative build · qualification evidence · repeatable batch delivery
The program is designed to preserve ion transport while improving mechanical stability, thermal behavior and abuse tolerance. Integration remains a development and qualification pathway—not a claim attached to every current ELVION build.
Evermore’s silicon work is aimed at the central problem: managing expansion through synthesis, particle behavior and electrode architecture without surrendering manufacturability.
The point is not to market every chemistry at once. It is to match the cell to the operating envelope.
High-energy applications where range and power density matter.
Cost, stability and safety-oriented applications.
Power and thermal behavior where the architecture permits.
Cycle life and fast-charge profiles for specialized duty cycles.
Particle structure, interfaces, coatings and transport pathways begin at the material level. The finished cell is the culmination of those decisions.
Evermore is advancing two separate cell programs: the large-format ELVION-X platform and the 6 Ah ELVION-S production design. Each has its own build and qualification path.
Platform target specific energy; the current large-format ELVION-X build measures approximately 300 Wh/kg.
Current ELVION-X cell capacity.
Measured mass of the current 64 Ah qualification build.
ELVION designs support up to 25% silicon; the current 6 Ah production-design pouch cell incorporates 10%.
The 6 Ah ELVION-S production design was submitted for independent UL 1642 and UN 38.3 pre-certification testing.
Pre-certification records report completion of all seven UN 38.3 categories applicable to cells.
Pre-certification test sequences were completed within the applicable acceptance criteria.
ELVION-X and ELVION-S are separate programs. Their specifications and qualification results should not be combined into a single cell claim.
Evermore designs safety behavior into the cell architecture, then studies what happens when a cell is damaged. The evidence must remain disciplined: tests inform engineering; they do not eliminate the need for application-specific qualification.
Formulation, electrodes, assembly, formation, testing and process records turn technical invention into a manufacturing system that can be deployed at larger scale.
Formulation, interfaces and electrode behavior.
Process settings, quality learning, failure analysis and records.

The objective is a financeable U.S. manufacturing project built from proven technical capability—not a speculative capacity announcement.
The North Texas plan converts an operating allied-country pilot base into a defined U.S. commercial line. Site, process, utilities, cost, schedule and demand must mature together.
Evermore is not proposing another demonstration line. The U.S. project is intended to convert an operating pilot base into 500 MWh per year of commercial production capacity.
Existing pilot equipment, production-representative batches, process learning and manufacturing records.
Cell sampling, independent testing, UL 1642 / UN 38.3 evidence and application-specific qualification.
Planned U.S. commercial cell production—not another pilot line.
Install equipment, validate yield and bring commercial output online against demand.
Project-development capital precedes construction financing. Facility credit should be sized only after site, line, cost, schedule, demand, compliance and operating-case evidence are documented.
Fund customer qualification, the U.S. operating team, site work, engineering and the cost-and-schedule package required for underwriting.
Align sponsor capital with eligible state, local and federal support. Public funding reduces project cost; it is not the primary repayment source.
Fund construction and production equipment after the project has documented demand, cost, compliance, sponsor support and repayment capacity.
