FAE Expert Insights
"Lithium-ion capacitors are Jianghai's new products, filling the gap between EDLC and lithium batteries. 220F/3.8V is suitable for 3.3V system applications, single cell can meet requirements (EDLC requires two in series). Note working voltage must not exceed 3.8V, minimum not below 1.8V, requires dedicated management IC."

Frequently Asked Questions
What are the key differences between LIC 220F/3.8V and EDLC supercapacitors?
LIC (Lithium-Ion Capacitor) differs from EDLC in several key aspects: 1) Voltage - LIC operates at 3.8V vs EDLC at 2.7V, enabling single-cell 3.3V designs; 2) Energy density - LIC offers 3-4x higher energy density (10-15 Wh/kg vs 3-5 Wh/kg); 3) Self-discharge - LIC has lower self-discharge rate (2-5% per day vs 5-20% for EDLC); 4) Cycle life - LIC provides 100,000+ cycles vs 500,000+ for EDLC; 5) ESR - LIC typically has higher ESR (15mOhm vs 3.5mOhm). LIC bridges the gap between batteries and supercapacitors, ideal for applications needing moderate energy storage with high cycle life.
Choose LIC for 3.3V systems requiring higher energy density and lower self-discharge. Choose EDLC for highest cycle life and lowest ESR applications.
What are the voltage management requirements for LIC 220F/3.8V?
LIC 220F/3.8V requires careful voltage management: 1) Absolute maximum voltage: 3.8V (exceeding causes permanent damage); 2) Minimum voltage: 1.8V (discharging below reduces cycle life); 3) Recommended operating range: 2.5V-3.8V for optimal performance; 4) Requires dedicated LIC management IC for charging control; 5) Unlike EDLC, LIC cannot be used in series without specialized balancing. Use a dedicated LIC charger IC (e.g., BQ25100) that limits charge voltage precisely to 3.8V with proper taper current control.
Always use dedicated LIC management ICs. Never exceed 3.8V or discharge below 1.8V to ensure safety and longevity.
