The problem: lithium-ion can't keep pace with EVs, renewables, and AI power demand — fire risk, short lifespans, and scarce materials hold it back.
The solution: one proprietary particle coating, unlocking two validated chemistries — lifetime aqueous sodium-ion and dendrite-free lithium-metal.
Engineered Particles wrap an active battery particle in an ion-conducting shell with embedded conductive carbon — a pre-formed protective layer that stops electrolyte breakdown, dendrite growth, and degradation at the source.
70,000+ cycles, no capacity fade
~100% coulombic efficiency, no gas
1C to more than 100C rate
Dendrite suppression, no formation step
Greater than 350 Wh/kg density
Greater than 80% retention, 400 cycles
Cycle life is a sodium-ion metric — compared against sodium-ion and legacy storage chemistries only.
| Technology | Result | Stage |
|---|---|---|
| Aqueous Na-ion, USA | 50,000+ cycles | Commercial |
| Solid-state Li-metal, USA | 95% @ 1,000 cyc. | Pilot line 2026 |
| Li-metal breakthrough, China | 500+ Wh/kg claimed | Early-stage |
| Solmax EP (both) | 70,000+ cyc. / 350+ Wh/kg | Lab / small-pilot |
EP is validated at lab and small-pilot scale (TRL 4-5), earlier than commercial-stage rivals above. Its advantage: a single coating process that upgrades standard battery manufacturing lines, rather than a new cell architecture — a faster, lower-cost path to scale once commercial coating throughput is reached.
Real, near-term deployment opportunities for the technology.
