These lithium-ion pouch cells require storage at partial state of charge in a dry, cool environment to minimize capacity fade. Avoid physical puncture, exposure to conductive materials, and temperatures exceeding the specified operating range to prevent thermal runaway or electrolyte degradation.
- Temperature and Atmosphere: Prolonged storage outside the -40°C to 60°C operating range accelerates electrolyte degradation and capacity loss.
- Storage State of Charge: Maintain cells at 30–50% state of charge for extended storage to reduce internal pressure and electrode degradation.
- Containment and Isolation: Store cells in fireproof, non-conductive containers and keep terminals insulated to prevent short circuits.
- Visual Inspection: Inspect each cell for swelling, leakage, or terminal corrosion before use and discard any damaged units.
- Charge Rate Limitation: Avoid charging above the manufacturer-recommended continuous charge rate to prevent internal lithium plating.
These high-energy-density pouch cells require careful inspection and controlled conditioning before deployment. Follow the steps below to safely prepare and verify cell integrity before integration into a battery pack.
Required Equipment: Insulated gloves, Digital multimeter, Fireproof storage container
- Inspect Cell
Inspect the pouch cell for any physical damage, swelling, or leakage before handling. - Measure Voltage
Measure the open-circuit voltage with a multimeter to verify it matches the nominal voltage of 3.6 V. - Secure Storage
Store the cell in a fireproof, non-conductive container when not in use to prevent short circuits.
How does the energy density of the Long Range Semi-Solid Battery Pouch Series compare to conventional lithium-ion pouch cells, and what is the trade-off for achieving 5C continuous discharge?
The series delivers an ultra-high energy density of 320–370 Wh/kg, which exceeds typical NMC pouch cells (250–300 Wh/kg) while still supporting 5C continuous and 7C pulse discharge. This is achieved through a semi-solid electrolyte design that reduces internal resistance and enables high power output without the cycle life penalty usually associated with high-energy formulations, maintaining ≥800 cycles to 80% SOH.
Can the AFEPSLR105105230 52Ah pouch cell be integrated into an existing 800V EV battery pack architecture without modifying the cooling system?
Yes, the cell's nominal voltage of 3.6V and wide operating temperature range of -40°C to 60°C allow direct integration into 800V packs via series stacking, but the cooling system must accommodate the cell's dimensions (10.5 × 105 × 230 mm) and weight (583 g). The semi-solid electrolyte reduces leakage risk and improves mechanical stability, simplifying thermal management compared to liquid-electrolyte cells.
What are the critical handling and storage requirements for the semi-solid electrolyte pouch cells to prevent performance degradation before installation?
Cells must be stored in moisture-barrier vacuum-sealed aluminum foil bags within anti-static cartons to prevent electrolyte contamination and short circuits. Pre-condition at 25°C before first high-rate discharge, and always operate within 2.75V–4.2V using a BMS with overcurrent and low-temperature protection to avoid irreversible capacity loss.
The ATOMFAIR Semi-Solid Battery Long Range Series delivers ultra-high energy density (320–370 Wh/kg) with enhanced safety from its semi-solid electrolyte, but requires active thermal management to avoid sustained temperatures above 60°C and careful handling of moisture-sensitive vacuum-sealed packaging, making it suitable for demanding applications like eVTOL and high-performance EVs.
Positive
- Ultra-High Energy Density for Extended Runtime: Achieving 320–370 Wh/kg, these cells enable lightweight pack designs and longest runtime, critical for eVTOL and high-performance EV applications.
- Enhanced Safety with Semi-Solid Electrolyte: The semi-solid electrolyte design reduces leakage and flammability while improving mechanical stability, offering a safer alternative to liquid electrolytes.
Trade-offs
- Thermal Management and Pre-Conditioning Required: Sustained operation above 60°C must be avoided, and cells require pre-conditioning at 25°C before first high-rate discharge, necessitating active thermal management and BMS integration.
- Moisture-Sensitive Vacuum-Sealed Packaging: Cells are shipped in moisture-barrier vacuum-sealed aluminum foil bags, requiring careful handling and storage to prevent moisture ingress that could degrade performance.
