AW-LIC-3R8-150

The AW-LIC-3R8-150 is rated for maximum continuous discharge current of 5A at 25°C, with peak currents up to 15A for 10 seconds. The continuous rating is limited by thermal considerations - at 5A, power dissipation in the 15mΩ ESR is 375mW (25 × 0.015), causing approximately 10°C temperature rise. The low ESR enables high power delivery relative to the cell size. For pulse applications, the 15A peak capability supports high-power bursts such as wireless transmission, motor starting, or LED flash. Voltage droop at 5A is 75mV (5A × 0.015Ω), negligible compared to the 3.8V nominal voltage. Current capability decreases at elevated temperatures - approximately 4A at 45°C and 2.5A at 65°C. For continuous currents above 5A, parallel connection of multiple cells is recommended to distribute current and heat load.

For continuous currents above 5A, parallel multiple cells or implement forced air cooling.

The AW-LIC-3R8-150 charge time depends on the charging current and starting voltage. At the maximum recommended charge current of 150mA (1C), charge time from 0V to 90% is approximately 9 minutes. At 75mA (0.5C) for extended cycle life, charge time is approximately 18 minutes. For rapid charging applications, up to 300mA (2C) can be used for short periods, achieving 90% charge in about 4.5 minutes, though this reduces cycle life. The cell accepts charge rapidly throughout the voltage range without the tapering characteristic of lithium batteries. Simple charging can be implemented with a current-limited supply set to 3.8V, though dedicated LIC charger ICs provide better voltage accuracy and safety features. The cell can be charged from any state of discharge without preconditioning. For fastest charging while maintaining cycle life, use 150mA CC-CV charging.

Use 150mA charging for best balance of speed and cycle life. Contact our FAE team for charger IC recommendations.

The AW-LIC-3R8-150 stores approximately 1.08 Wh of total energy (E = 0.5 × 150F × 3.8V² = 1083 Joules = 0.301 Wh - correction: E = 0.5 × 150 × 14.44 = 1083 J = 0.301 Wh). Usable energy depends on the minimum operating voltage of your system. For a typical application operating from 3.8V down to 3.0V: Usable energy = 0.5 × 150F × (3.8² - 3.0²) = 0.5 × 150 × 5.44 = 408 Joules = 0.113 Wh. For systems with DC-DC converters that can operate down to 2.2V: Usable energy = 0.5 × 150F × (3.8² - 2.2²) = 0.5 × 150 × 9.6 = 720 Joules = 0.2 Wh. This usable energy can power a 3.3V, 50mA load (165mW) for approximately 0.68 hours or 41 minutes when discharged to 3.0V. The high energy density of 28 Wh/kg means more energy in a smaller package than EDLC alternatives.

The AW-LIC-3R8-150 can replace small lithium batteries in specific applications but requires careful evaluation. Comparison with a typical 1000mAh lithium coin cell (3V, 3Wh): The 150F hybrid stores 0.3Wh total, about 10% of the battery's energy. However, the hybrid capacitor offers: unlimited charge cycles vs 500 for the battery, rapid charging in minutes vs hours, wide temperature operation (-40°C to +65°C vs 0°C to 45°C), 10+ year calendar life vs 3-5 years for the battery, and no fire/explosion risk. Suitable replacement scenarios: Applications with frequent charging (daily or more), burst power requirements with standby periods, wide temperature operation needs, or safety-critical applications. Unsuitable scenarios: Long runtime requirements (days) between charging, very low self-discharge requirements (months of standby), or extreme cost sensitivity. Many designs benefit from hybrid-battery combinations, using the hybrid for high-power bursts and battery for long-term energy storage.

The AW-LIC-3R8-150 contains lithium and is subject to shipping regulations, though exemptions apply due to the small quantity. The cell contains approximately 0.15g of lithium, well below the 1g limit for UN 38.3 testing exemption per IATA Section II. This means: No dangerous goods documentation is required for air shipment of small quantities (typically up to 4 cells per package). The package must be labeled with the lithium battery handling label. Cells should be shipped at 30% state of charge or less for maximum safety. For ocean and ground transport, similar exemptions apply for small lithium content. For larger quantities, UN 38.3 testing and Class 9 dangerous goods classification may apply. The cell is not classified as hazardous waste for disposal under most regulations. Always check current regulations as they may change. Aowei provides Material Safety Data Sheets (MSDS) and shipping documentation upon request.

State of charge (SOC) monitoring for the AW-LIC-3R8-150 can be implemented using voltage measurement with appropriate compensation. Unlike batteries, hybrid capacitors have a nearly linear voltage vs. SOC relationship, making SOC estimation straightforward. At 3.8V = 100% SOC, 3.3V ≈ 50% SOC, and 2.2V = 0% SOC. Simple voltage monitoring with a microcontroller ADC provides reasonable SOC accuracy (±10%). For better accuracy, implement a simple lookup table accounting for temperature effects - voltage drops approximately 100mV at -40°C compared to 25°C. Current integration (coulomb counting) can improve accuracy but is generally unnecessary for hybrid capacitors due to the linear voltage relationship. The cell's low self-discharge means voltage-based SOC remains valid for weeks. For systems with displays, a simple 4-bar or percentage indicator based on voltage is sufficient. No complex battery gas gauge ICs are required, reducing system cost and complexity.

Simple voltage monitoring provides adequate SOC indication for most applications. Contact our FAE team for reference circuits.
