As the demands on energy storage systems grow—especially in telecom, backup, and remote applications—the limitations of lithium-ion batteries are being exposed: limited cycle life, thermal risks, and degradation under real-world conditions.
At Emtel Group, we offer a fundamentally different approach with our ENCAP supercapacitor modules, based on electrostatic storage. Here’s how they work—and how they differ from traditional electrochemical batteries.
How ENCAP Works: Charge Without Chemical Reaction
Unlike lithium-ion batteries, which rely on chemical reactions to store energy, ENCAP modules store energy via electrostatic charge. No chemical transformation = no material degradation.
Key Benefits:
• Fast charging and discharging
• Stable performance across thousands of cycles
• Minimal heat generation under load.
🔋 Electrochemical vs Electrostatic: What’s the Difference?
Feature | Lithium-ion Battery | ENCAP Supercapacitor (Electrostatic) |
Energy Storage Mechanism | Electrochemical reaction | Electrostatic charge separation |
Typical Cycle Life | 5,000–6,000 cycles | Up to 500,000 cycles (cell level) |
Response Time | Milliseconds | 400 nanoseconds (measured) |
Depth of Discharge (DoD) | 70–90% (limited by lifespan) | 100% usable DoD |
Thermal Risk | High (thermal runaway risk) | Extremely low |
Operating Temperature | Narrow range (needs cooling) | Wide range, passive cooling |
Degradation Over Time | Significant | Minimal |
Cooler, Safer, Simpler
Thermal management is one of the biggest pain points in lithium systems. ENCAP solves this:
• No thermal runaway
• No flammable electrolytes
• No active cooling required
ENCAP systems are passively cooled and operate reliably in desert heat, mountain cold, and other harsh field environments.
Realistic Long-Term Performance
ENCAP cells are rated for up to 500,000 cycles under standard conditions. Even at the module or system level, you can expect over 50x the cycle life of lithium-ion solutions.
• Ideal for frequent cycling applications like solar-buffering, peak shaving, telecom tower backup, and generator offset
• System lifetime is no longer defined by the weakest cell chemistry
Simpler System Design
Because ENCAP modules tolerate aggressive depth of discharge and high cycling, system designs can:
• Use 100% of installed capacity with no oversizing
• Avoid degradation planning or derating curves
• Reduce maintenance, cooling costs, and fire safety requirements
Proven in the Field
ENCAP is powering critical infrastructure in off-grid telecom towers, remote sites, and harsh environments where lithium fails or requires costly engineering workarounds.
Our solutions have already proven successful in locations like:
• Afghanistan’s high-altitude mountain sites
• 350kW Electrostatic Power Solution for Data Centers.
• GCC-region off-grid and diesel-hybrid systems
