Operate only within specified voltage and temperature limits to prevent thermal runaway. Use only with a compatible BMS providing over-discharge, over-current, and cell balancing protection.
- Storage Requirement: Store the battery in a dry, ventilated area at 20±5°C away from flammable materials.
- Charge Restriction: Charge at 1C rate within the manufacturer's recommended voltage range using a compatible charger.
- Discharge Limit: Do not exceed the rated peak discharge duration of 10C for 10 seconds.
- Preconditioning: Pre-condition new cells at a suitable temperature before first use to stabilize electrochemistry.
- Disposal Directive: Dispose of cells in accordance with local regulations for lithium-ion batteries.
Follow these steps to safely prepare and operate the battery pack. Proper initialization ensures optimal performance and longevity.
Required Equipment: Compatible Battery Management System (BMS), Compatible charger, Multimeter for voltage verification
- Inspect packaging
Inspect the moisture-barrier vacuum-sealed packaging for any damage before opening. - Connect BMS
Connect the battery to a compatible BMS with over-discharge, over-current, and cell balancing protection. - Charge the battery
Charge the battery at 1C rate within the manufacturer's recommended voltage range using a compatible charger. - Precondition cells
Pre-condition the battery at a suitable temperature for at least one hour before first use. - Verify voltage and discharge limits
Verify the cell voltage and ensure the discharge rate does not exceed the rated peak duration.
How does the energy density trade off against cell voltage and weight across the ATOMFAIR 3.95V semi-solid battery series configurations?
The 6S model (AF3953106S) achieves 270 Wh/kg at 23.7 V and 2700 g, while the 18S model (AF3953118S) delivers 280 Wh/kg at 71.1 V and 7800 g. Higher voltage configurations like 12S and 18S provide greater energy density due to improved packing efficiency, but at significantly increased mass and dimensions (199.5 mm length vs 68.5 mm for the 6S). The 12S and 18S both attain 280 Wh/kg, making them optimal for applications requiring maximum energy per weight at the cost of higher voltage and physical size.
What specific BMS features are required to safely operate the 31Ah semi-solid battery in high-discharge UAV applications?
A BMS with over-discharge protection, over-current protection, and cell balancing is mandatory. Given the battery supports 5C continuous (155 A) and 10C peak (310 A) discharge, the BMS must be rated for these currents. Cells must be pre-conditioned at a suitable temperature before first use, and charging should be limited to 1C (31 A) within the manufacturer’s recommended voltage range for the 3.95 V nominal cell chemistry.
What are the critical storage and preconditioning steps required to maintain the performance and safety of the semi-solid electrolyte pouch cells?
Store cells in moisture-barrier vacuum-sealed aluminum foil bags to prevent electrolyte contamination and maintain thermal stability. Prior to first use, pre-condition new cells at a suitable temperature as specified by the manufacturer. Avoid prolonged exposure to excessive temperatures and never exceed the rated peak discharge duration. Dispose of cells in accordance with local regulations.
The 3.95V 280Wh/kg Semi-Solid Battery 31Ah series offers ultra-high energy density and high rate capability (5C continuous, 10C peak) in four voltage configurations, but requires careful thermal management and a mandatory external BMS for safe operation.
Positive
- Ultra-High Energy Density 280Wh/kg: Achieves 280Wh/kg energy density, enabling extreme lightweight design for UAVs and portable devices.
- Enhanced Safety from Semi-Solid Electrolyte: Semi-solid electrolyte reduces leakage risk and improves thermal stability compared to conventional liquid electrolytes.
Trade-offs
- Mandatory External BMS Requirement: Operation requires a compatible BMS with over-discharge, over-current, and cell balancing protection to prevent damage.
- Environmental Sensitivity During Operation: Cells must be pre-conditioned at suitable temperature before first use and protected from excessive temperature exposure; peak discharge duration must not be exceeded.
