SODIUM-ION ENERGY STORAGE
TECNED integrates sodium-ion battery technology into modular building blocks and complete energy systems — from 48 V DC battery modules to UPS-grade energy platforms and scalable BESS cabinets.
THE PLATFORM
From modular 48 V energy storage to UPS-grade power systems and complete commercial BESS installations.
Telecom | DC Power Rooms | 48 V Microgrids | Commercial Backup
Industrial Processes | Hospitals | Public Infrastructure | Generator Optimisation
Peak Shaving | Load Shifting | Microgrids | PV Integration | Grid Support
Why Sodium-ion?
Sodium-ion technology offers a different approach to stationary energy storage. Rather than prioritising maximum energy density, TECNED’s platform focuses on safety, predictable behaviour and long-term operation in professional indoor environments.
Critical Power | 48 V DC | UPS Systems | Industrial Energy Storage
The sodium-ion platform
Safe sodium-ion chemistry designed for controlled operation in technical environments.
Stable and predictable degradation behaviour for long-term stationary applications.
Flexible building blocks for DC architectures, hybrid systems and scalable installations.
Supports energy management strategies including peak shaving and load shifting.
Built for professional environments requiring robust, serviceable energy infrastructure.
Designed for predictable operation across demanding environmental conditions.
THE TECHNOLOGY
Sodium-ion is not a single chemistry. TECNED deliberately selects NFPP-based cells because they offer strong thermal stability and predictable lifetime behaviour for stationary infrastructure applications.
| Feature | NFPP (Polyanionic) | Layered Oxides | Prussian White (PBA) |
| Crystal Structure | 3D Polyanionic / NASICON framework | 2D Layered sheets (similar to NMC) | Open-framework cubic lattice |
| Energy Density | Lowest (~100–120 Wh/kg) | Highest (~140–175 Wh/kg) | Medium-High (~155–170 Wh/kg) |
| Cycle Life | Exceptional (8,000 to 10,000+ cycles) | Shortest (2,000 to 4,000 cycles) | Moderate (2,000 to 5,000 cycles) |
| Thermal Runaway | Highest safety (>270°C) | Lowest stability (~160°C–200°C) | Safe (unless severe overcharge occurs) |
| Principal Benefit | Extreme durability & absolute safety | Highest capacity & drop-in manufacturing | Low raw material cost & cold performance |
| Main Application | Indoor energy storage / back-up | Micro EVs, scooters, compact cars | Large scale power back-up |
Conclusion: NFPP chemistry prioritises safety and predictability over maximum energy density. This aligns with TECNED’s design philosophy for indoor ESS, energy-optimised UPS systems, and long-life 48 V architectures where controlled behaviour and insurer-friendly risk profiles are essential.
Sodium-ion vs. Lead-acid vs. LFP measured by UPS-critical metrics
| Behavior | NFPP sodium-ion | LFP lithium-ion |
| Deep cycle Life | Ultra-Long deep cycle life due to rigid crystal lattice | LFP lifespan declines when cycled at high depth |
| Low temperature operation | No preheating required. No adverse effect / dendrite formation | Preheating required to prevent dendrite formation |
| Heavy mechanical abuse | Failure results in lower temperature events / cell to cell propagation less likely | Failure cause high temperature catastrophic events causing cell to cell propagation |
| Heavy electrical abuse | Higher resistance against overvoltage | Overvoltage will cause failure |
| Metal deposition at negative electrode (note) | Unlikely, limited deposits only under extreme abuse | Main cause for short circuit and failure |
| Dangerous gas release in failure mode | Primary non-toxic/lower risk gases | hazardous, carbon-rich smoke / vapors |
| SEI layer stability | Low resistance, highly stable SEI layer prevents spike grow | Repeated SEI layer reconstruction allow spikes grow |
| Oxygen release during failure mode | Stronger resistance to oxygen release and thermal runaway | Less strong bonding to oxygen due to less ridged crystal structure |
