These semi-solid battery cells require strict voltage and temperature management to ensure safety and longevity. Always use a compatible BMS and pre-condition cells before high-rate discharge.
- Voltage Limits: Operate the cell strictly within 2.75V to 4.2V to prevent over-discharge or overcharge damage.
- Temperature Management: Avoid sustained exposure above 60°C and pre-condition the cell at 25°C before first high-rate discharge.
- BMS Requirement: Always integrate a battery management system with overcurrent and low-temperature protection.
- Moisture Sensitivity: Store cells in moisture-barrier vacuum-sealed packaging to prevent electrolyte degradation.
- Cycle Life Expectancy: The cell delivers ≥800 cycles to 80% state of health under standard 1C/1C cycling conditions.
Follow these steps to prepare the cell for first use and ensure safe operation under high-rate discharge conditions. Proper preconditioning and BMS integration are critical for performance and safety.
Required Equipment: Battery Management System (BMS) with overcurrent and low-temperature protection, Temperature-controlled environment (25°C), Voltage measurement device
- Inspect Packaging
Inspect the moisture-barrier vacuum-sealed packaging for any punctures or damage before opening. - Pre-condition Cell
Pre-condition the cell at 25°C in a temperature-controlled environment for at least 2 hours before first use. - Connect BMS
Connect the cell to a compatible BMS configured with overcurrent and low-temperature protection thresholds. - Set Voltage Limits
Set the charge and discharge voltage limits to 2.75V minimum and 4.2V maximum respectively. - Verify Temperature
Verify that the cell temperature is stable at 25°C before initiating any high-rate discharge cycle. - Monitor Operation
Monitor cell temperature continuously during operation and discontinue use if it exceeds 60°C.
How does the ultra-high energy density of 340–370 Wh/kg affect the cycle life under high-rate discharge conditions?
Despite its high energy density, the battery maintains ≥800 cycles to 80% SOH under 1C/1C cycling while supporting 5C continuous and 7C pulse discharge for 3 minutes. The semi-solid electrolyte design yields low internal resistance, enabling both high energy and power without disproportionate cycle life degradation within the specified test regime.
What are the voltage window and BMS requirements for integrating this semi-solid pouch cell into an eVTOL or UAV power system?
The cell operates within 2.75V to 4.2V at a nominal 3.5V. Integration requires a BMS with overcurrent and low-temperature protection. The two available pouch formats (106×74×172 mm at 305 g or 88×87×188 mm at 325 g) must be accommodated in pack design, and custom dimensions are available upon request.
What storage, preconditioning, and handling procedures are required to ensure safe operation of this semi-solid electrolyte battery?
Cells are shipped in moisture-barrier vacuum-sealed bags; storage should avoid sustained temperatures above 60°C. Pre-condition at 25°C before first high-rate discharge. The semi-solid electrolyte reduces leakage and flammability, but a BMS with overcurrent and low-temperature protection remains mandatory for safe operation within the specified voltage and temperature limits.
This semi-solid battery provides ultra-high energy density (340–370 Wh/kg) and high power capability (5C continuous, 7C pulse) for demanding applications, but requires strict voltage (2.75–4.2V) and temperature (≤60°C) control along with a BMS for safe high-rate operation.
Positive
- Ultra-High Energy Density and Power Output: Delivers 340–370 Wh/kg with 5C continuous and 7C pulse discharge, enabling long runtime and high power in lightweight packs for eVTOL, EVs, and robotics.
- Enhanced Safety with Semi-Solid Electrolyte: The semi-solid electrolyte design reduces leakage and flammability while improving mechanical stability, offering safer operation compared to conventional liquid electrolytes.
Trade-offs
- Strict Voltage and Temperature Limits: Cells must be operated within 2.75V–4.2V and sustained temperature above 60°C must be avoided, requiring precise thermal management and voltage regulation in system design.
- Requires BMS and Pre-Conditioning: A BMS with overcurrent and low-temperature protection is mandatory, and cells must be pre-conditioned at 25°C before first high-rate discharge to ensure safe operation.
