In energy storage systems, thermal management is often the hidden cost—one that affects reliability, safety, and total cost of ownership. For lithium-ion batteries, heat is a critical design factor due to their chemical nature and fire risk.
At Emtel Energy we’ve taken a different approach. Our Enercap’s ENCAP supercapacitor modules use electrostatic energy storage, erasing the primary cause of thermal buildup that is chemical reaction.

Heat Generation: Lithium vs ENCAP
Property | Lithium-ion Battery | ENCAP Supercapacitor Module |
Heat Source | Electrochemical reaction & IR drop | ESR only (no reaction heat) |
Charge/Discharge Heating | Moderate to High | Minimal, even at high C-rates |
Risk of Thermal Runaway | High | None |
Cooling Requirement | Active (air/liquid) | Passive (natural convection) |
Safe Ambient Operating Range | 0°C to ~45°C (typically) | -20°C to +65°C (tested and stable) |
ENCAP cells operate with extremely low internal resistance (ESR), meaning less heat is generated during charge and discharge cycles—even under high current conditions (up to 10C).
Proven in Extreme Conditions
ENCAP has been deployed in:
• The Pamir Mountains of Afghanistan at high altitude with large ambient swings
• Middle Eastern deserts where internal lithium systems would derate or shut down
• Passive cabinet retrofits with no fans, where heat-sensitive batteries failed
Summary: Heat Isn’t a Problem—It’s a Strength
ENCAP’s electrostatic architecture gives it inherent thermal resilience:
• No thermal runaway
• No chemical degradation from heat
• No complex cooling systems needed
This simplifies deployment, increases uptime, and slashes OPEX for mission-critical sites.
