These semi-solid electrolyte pouch cells require moisture-barrier vacuum-sealed packaging to prevent electrolyte degradation and must be stored within the manufacturer's recommended temperature range to avoid thermal runaway risk. A compatible Battery Management System (BMS) with over-discharge, over-current, and cell balancing protection is mandatory for all operational configurations.
- Storage Environment: Store cells in a dry, cool environment away from direct sunlight and heat sources to maintain electrolyte stability and prevent swelling.
- BMS Requirement: Integrate a BMS that enforces over-discharge protection below the minimum cell voltage and limits charge current to the rated 2C maximum.
- Thermal Management: Avoid exposing cells to temperatures exceeding 60°C during operation or storage to prevent irreversible capacity loss and internal short circuits.
- Pre-conditioning: Pre-condition new cells at a suitable temperature (typically 20–25°C) for at least 2 hours before first use to stabilize the electrolyte.
- Disposal Compliance: Dispose of end-of-life cells in accordance with local hazardous waste regulations to prevent environmental contamination from electrolyte components.
This procedure covers the safe unpacking, pre-conditioning, and first charge cycle for the semi-solid pouch cells to ensure optimal performance and safety. Follow each step sequentially to avoid damage to the cell or injury from electrical or chemical hazards.
Required Equipment: Compatible BMS with cell balancing, Constant-current/constant-voltage (CC-CV) charger rated for the cell voltage, Insulated gloves and safety goggles, Non-conductive work surface
- Inspect Packaging
Inspect the moisture-barrier vacuum-sealed bag for any punctures or tears before opening to confirm the cell has not been exposed to ambient humidity. - Pre-condition Cell
Allow the cell to rest at room temperature (20–25°C) for at least 2 hours after unpacking to stabilize the semi-solid electrolyte. - Connect BMS
Connect the cell to a compatible BMS that provides over-discharge, over-current, and cell balancing protection before any electrical connection. - Set Charger Parameters
Set the CC-CV charger to the nominal voltage of the specific model (e.g., 23.7V for 6S) and limit the charge current to 2C (40A for a 20Ah cell). - Perform First Charge
Initiate the first charge cycle in a well-ventilated area and monitor the cell temperature to ensure it does not exceed 45°C during charging. - Verify Voltage
After charging, verify the cell voltage with a multimeter to confirm it matches the nominal voltage within ±0.1V before connecting to the load. - Discharge Test
Perform an initial discharge at 1C (20A) to confirm the cell delivers rated capacity without excessive voltage drop or heating.
What are the trade-offs between choosing a 6S versus an 18S configuration of the ATOMFAIR 20Ah semi-solid battery for a drone application?
The 6S configuration (23.7V) is lighter at 2000g and more compact at 54×89×205mm, while the 18S configuration (71.1V) is heavier at 5750g and larger at 156×89×205mm. Both offer the same 20Ah capacity and 240Wh/kg energy density, so the trade-off is lower voltage and weight versus higher voltage and power capability, depending on the drone's voltage and space requirements.
What BMS specifications are required for integrating the ATOMFAIR 20Ah semi-solid battery into a robotic system?
The battery requires a BMS with over-discharge, over-current, and cell balancing protection as stated in the important notice. The BMS must also be compatible with the nominal voltage of the chosen configuration (23.7V for 6S up to 71.1V for 18S) and support a 2C charge rate (40A) and 5C continuous discharge rate (100A).
What are the storage and preconditioning requirements for the ATOMFAIR 20Ah semi-solid battery before first use?
Store the battery in its moisture-barrier vacuum-sealed aluminum foil packaging to prevent moisture ingress. Before first use, pre-condition new cells at a suitable temperature as recommended in the notice, and avoid exposing cells to excessive temperatures for extended periods. Dispose of cells in accordance with local regulations.
The ATOMFAIR 3.95V 240Wh/kg Semi-Solid Battery 20Ah series delivers high energy density and high-rate capability (2C charge, 5C continuous, 10C peak) in flexible voltage configurations (6S–18S), but requires careful BMS integration and thermal preconditioning to ensure safe operation under peak loads.
Positive
- High energy density 240 Wh/kg: Enables extended runtime in lightweight UAV, robotics, and portable power station designs, reducing overall system mass for a given capacity.
- High rate capability 2C/5C/10C: Supports 2C fast charge, 5C continuous discharge, and 10C peak discharge, suitable for high-power demands in drones, robotics, and electric equipment.
Trade-offs
- Requires compatible BMS protection: Mandatory use of a BMS with over-discharge, over-current, and cell balancing protection to prevent damage and ensure safe operation.
- Thermal preconditioning needed: New cells must be preconditioned at a suitable temperature before first use, and prolonged exposure to excessive temperatures must be avoided to maintain performance and safety.
