Operate the cell within its specified temperature range of -40°C to 60°C to maintain performance and prevent thermal runaway. Handle the pouch cell with care to avoid puncture or deformation that could compromise the semi-solid electrolyte barrier.
- Operating Temperature Range: Maintain cell temperature between -40°C and 60°C during discharge to ensure stable electrochemical performance and avoid capacity degradation.
- Cycle Life Degradation: The cell delivers at least 800 cycles to 80% state of health under 1C/1C cycling, after which gradual capacity fade accelerates and replacement is recommended.
- Discharge Current Limits: Do not exceed 5C continuous discharge or 7C pulse discharge for longer than 3 minutes to prevent internal heating and permanent damage.
- Mechanical Integrity: Avoid mechanical stress, puncture, or crushing of the pouch cell to maintain the integrity of the semi-solid electrolyte and prevent short circuits.
Initialize the semi-solid battery pouch cell for safe integration into high-energy applications such as eVTOL or high-performance EVs. Follow these steps to configure charging and operational parameters based on manufacturer specifications.
Required Equipment: Battery management system (BMS) calibrated to 3.5 V nominal, Temperature sensor or environmental chamber, Insulated handling gloves and non-conductive work surface
- Inspect pouch integrity
Inspect the pouch cell for physical damage, swelling, or leakage before any electrical connection is made. - Connect to BMS
Connect the cell leads to a BMS configured to the nominal voltage of 3.5 V and with overcharge protection enabled. - Set temperature range
Verify the operating environment maintains the cell temperature between -40°C and 60°C throughout the charge-discharge cycle. - Configure discharge limits
Program the BMS to limit continuous discharge to 5C and pulse discharge (≤3 minutes) to 7C per cell specifications. - Perform initial charge
Charge the cell using a constant current constant voltage (CCCV) profile with an upper voltage limit of 3.5 V to reach full capacity.
How does the semi-solid electrolyte in the Max Energy series affect internal resistance and rate capability compared to conventional liquid electrolyte pouch cells?
The semi-solid electrolyte design reduces internal resistance and enhances safety by eliminating liquid leakage and lowering flammability, while still supporting 5C continuous and 7C pulse discharge for 3 minutes. This enables high power output without the mechanical instability risks associated with liquid electrolytes, as confirmed by the product's stable performance across -40°C to 60°C and ≥800 cycles to 80% SOH.
Can the AFEPSME10674172 or AFEPSME88871888 pouch cells be integrated into existing eVTOL battery packs designed for standard lithium-ion pouch formats?
Yes, both models are standard pouch formats—10.6 × 74 × 172 mm and 8.8 × 87 × 188 mm—with a nominal voltage of 3.5 V and 30 Ah capacity, allowing direct mechanical integration into many existing pack designs. However, the BMS must be configured for the 2.75V–4.2V operating window and include overcurrent and low-temperature protection as specified in the product notice.
What storage and handling conditions are required to maintain the semi-solid electrolyte's integrity and prevent capacity fade before first use?
Cells are shipped in moisture-barrier vacuum-sealed aluminum foil bags inside anti-static cartons to prevent electrolyte degradation. For optimal performance, pre-condition at 25°C before first high-rate discharge, avoid sustained temperatures above 60°C, and always operate within 2.75V–4.2V using a BMS with overcurrent protection.
The ATOMFAIR Semi-Solid Battery Max Energy Series delivers 340–370 Wh/kg with 5C continuous discharge capability, making it suitable for high-energy and high-power applications such as eVTOL and performance EVs. However, operation requires strict voltage compliance (2.75V–4.2V) and thermal management below 60°C, with preconditioning needed before first high-rate discharge.
Positive
- Ultra-High Energy Density: 340–370 Wh/kg enables extended runtime and lightweight pack designs for demanding applications like eVTOL and high-performance EVs, directly improving system-level energy efficiency.
- Wide Temperature Range with Semi-Solid Safety: Operates reliably from -40°C to 60°C with a semi-solid electrolyte that reduces leakage and flammability, enhancing mechanical stability in extreme environments.
Trade-offs
- Strict Voltage Window Requirements: Operation must be confined to 2.75V–4.2V; deviations can degrade performance or safety, requiring precise BMS management to protect cycle life and avoid thermal runaway.
- Thermal and Conditioning Constraints: Sustained temperatures above 60°C must be avoided, and pre-conditioning at 25°C before first high-rate discharge is recommended to ensure optimal capacity and impedance consistency.
