Store cells in a dry, cool environment below 25°C with relative humidity under 60% to prevent electrolyte degradation and internal short circuits. Always integrate a compatible BMS with over-discharge, over-current, and cell balancing protection to mitigate thermal runaway risk.
- Thermal Stability Constraint: Avoid exposing cells to temperatures exceeding 60°C during storage or operation to prevent irreversible capacity loss and potential venting.
- Charge Voltage Constraint: Charge strictly within the manufacturer's recommended voltage range to avoid over-voltage-induced lithium plating and internal short circuits.
- Discharge Rate Constraint: Do not exceed the rated 10C peak discharge duration to prevent excessive heat generation and cell swelling.
- Pre-conditioning Requirement: Pre-condition new cells at a suitable temperature before first use to stabilize the semi-solid electrolyte interface and ensure consistent performance.
Follow these steps to safely prepare and integrate the semi-solid battery pack into a system. Proper handling ensures optimal performance and minimizes safety risks.
Required Equipment: Compatible Battery Management System (BMS) with over-discharge, over-current, and cell balancing protection, Constant-current/constant-voltage (CC/CV) charger rated for the pack's nominal voltage, Multimeter or battery analyzer for voltage verification
- Inspect packaging and cell condition
Inspect the moisture-barrier vacuum-sealed bag for punctures or swelling before opening to confirm cell integrity. - Verify cell voltage
Measure the open-circuit voltage of each cell with a multimeter to ensure it is within the manufacturer's specified storage range. - Connect BMS
Connect a compatible BMS to the cell terminals, ensuring correct polarity and secure connections for over-discharge and over-current protection. - Pre-condition cells
Allow new cells to rest at a suitable temperature (20–25°C) for at least 2 hours before first charge to stabilize the electrolyte interface. - Perform initial charge
Charge the pack using a CC/CV charger at a 0.5C rate until the nominal voltage is reached, monitoring cell temperatures to stay below 45°C. - Verify pack voltage and balance
Confirm the pack voltage matches the nominal voltage and that all cells are balanced within 20 mV using the BMS readout. - Integrate into system
Connect the charged pack to the device, ensuring the load does not exceed the continuous 5C discharge rating during operation.
How does the choice between 6S and 18S configurations affect system voltage and physical footprint for UAV integration?
The 6S configuration (AF3952506S) delivers a nominal voltage of 23.7V with dimensions 65.5×89×205 mm and weight 2450 g, while the 18S configuration (AF3952518S) provides 71.1V but at 190.5×89×205 mm and 7000 g. This trade-off allows designers to match system voltage requirements against available space and payload capacity in drones or robotics.
What BMS specifications are required to safely integrate the 3.95V semi-solid battery series into a high-rate drone power system?
A compatible BMS must provide over-discharge protection, over-current protection, and cell balancing for the series configuration. The product notice also requires charging within the manufacturer’s recommended voltage range; consult the full datasheet for exact voltage limits to ensure safe operation under 2C charge and 5C continuous discharge.
What are the recommended storage conditions and pre-conditioning procedures for the semi-solid electrolyte pouch cells to ensure optimal performance and safety?
Cells are shipped in moisture-barrier vacuum-sealed aluminum foil bags and should be stored in anti-static cartons at a suitable temperature. Before first use, pre-condition new cells at a suitable temperature as recommended by the manufacturer, and avoid prolonged exposure to excessive temperatures to maintain thermal stability and reduce leakage risk.
The 3.95V semi-solid battery series delivers 250 Wh/kg energy density with 2C charge and 5C continuous discharge capability, but requires a compatible BMS and careful thermal management to avoid extended high-temperature exposure.
Positive
- High energy density 250 Wh/kg: Provides extended runtime in lightweight designs, ideal for UAVs and portable power applications where mass and volume are critical.
- High rate capability 2C/5C/10C: Supports 2C fast charging, 5C continuous discharge, and 10C peak discharge to meet power-demanding loads in drones, robotics, and portable stations.
Trade-offs
- Mandatory external BMS: Requires a compatible Battery Management System with over-discharge, over-current, and cell balancing protection to ensure safe operation and prevent cell damage.
- Sensitive to prolonged high temperature: Prolonged exposure to excessive temperatures must be avoided; pre-conditioning at suitable temperature before first use is recommended to maintain performance and safety.
