Evermore is a U.S.-controlled, TRL 8 battery platform advancing silicon-enhanced cells, proprietary semi-solid electrolyte technology and configurable chemistry from operating pilot production toward a planned 500 MWh commercial facility in Texas.
Evermore is a U.S.-controlled battery company developing silicon-enhanced lithium-ion cells, proprietary semi-solid electrolyte technology and configurable NCM, LMFP, LMO and LTO cell architectures for defense, aerospace, autonomous systems and high-reliability commercial applications.
Evermore’s semi-solid electrolyte architecture is designed to reduce free liquid movement inside the cell, limiting leakage and the conditions that can accelerate ignition and thermal propagation under mechanical or thermal abuse.
Explore the architectureSilicon-enhanced anodes increase capacity. Evermore combines material synthesis, electrode design and cell-level controls to manage expansion—10% silicon in the current ELVION-S design, with platform development extending up to 25%.
Explore the architectureNCM, LMFP, LMO and LTO provide a chemistry palette. Format, loading, interfaces and process conditions are configured around the customer’s safety, energy, power, temperature and duty-cycle requirements.
Explore the architecturePhysical cells, test evidence and production-representative batches support customer qualification.
The pilot establishes process knowledge, batch discipline and manufacturing evidence.
Texas is planned as commercial production—not another demonstration line.
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 passed all required UL 1642 and UN 38.3 test sequences in independent pre-certification testing conducted by Element, a globally recognized testing, inspection and certification firm. Formal certification documentation will be completed before commercial shipment.
Up to 25% silicon and semi-solid integration are platform development objectives—not the current ELVION-X production specification.
Performance follows from control of the cell architecture.
Evermore-developed hybrid electrolyte architecture that changes the safety and transport environment inside the cell.
Core platform backboneSilicon-enhanced current architectures plus internal synthesis pathways designed to push future energy performance.
Current + roadmapNCM, LMFP, LMO and LTO give Evermore a chemistry palette rather than a one-chemistry product line.
Application tunabilityGeometry, format, loading, interfaces and process conditions are configured around the customer’s operating envelope.
Mission-specific designThe 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.

Put real cells into customer evaluation programs.
Turn performance, safety and process evidence into procurement confidence.
Deliver enough repeatable volume to support early mission programs before full U.S. scale.
The same cell-level advantages produce different outcomes depending on the customer and application.

Reduced failure consequences under abuse and thermal stress.
Higher utilization where duty cycle matters.
A trusted manufacturing path for mission-critical programs.
Evermore develops the materials, engineers the cell, industrializes the process and uses that operating knowledge to expand U.S. capacity.
Technical differentiation creates the opportunity. Manufacturing and commercial discipline determine the outcome.

The North Texas plan scales Evermore’s operating pilot and process-development 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.
