Key Features & Advantages

  • High-Energy Architecture Layout: Combines a ≥310 Wh/kg gravimetric rating with a solid ≥700 Wh/L volumetric profile to yield compact, lightweight battery module groupings.
  • Superior Current Handling Kinetics: Seamlessly manages a continuous 3.0C continuous draw rate alongside an intensive 5.0C pulse acceleration window lasting up to 30 seconds.
  • Extensive Thermal Environment Capability: Offers highly stable energy dissipation paths down to a severe -20 °C cold snap up to a high 60 °C hot-spot boundary.
  • Extended Cycle Life Endurance: Achieves ≥500 full loops to 80% capacity retention under continuous test environments with an initial coulombic efficiency crossing past 99.5%.
  • Production Traceability Quality System: Every batch unit undergoes automated validation recording for nominal capacity matching, internal AC resistance, and open-circuit potential.

APPLICATION SCOPE: Electric vehicle main power arrays, advanced commercial robotics, portable high-density digital communication devices, high-end marine actuators, and specialized localized backup energy storage blocks.
OPERATIONAL COMPLIANCE NOTICE: High-density composite pouch cells are highly vulnerable to internal volume expansion shifts, localized overcharge potentials, and mechanical stress damage. Keep cells stored within their original environmental isolation wrappers until final system integration steps. Secure cell strings within dry, ventilated storage spaces maintained between a constant 15 °C – 30 °C thermal envelope. Never disassemble the pouch structure or expose terminals to open flame. Map active matrices exclusively to multi-channel management cards configured with integrated overcurrent and sub-zero charge cutoff relays.

The cell must be operated within specified current limits to prevent thermal runaway. Mechanical integrity of the pouch enclosure must be maintained to avoid electrolyte leakage.

  • Current Compliance: Continuous discharge must not exceed 3.0C (105 A) and pulse discharge must not exceed 5.0C (175 A).
  • Mechanical Handling: The pouch cell must not be punctured, creased, or subjected to compressive forces that could damage the laminate seal.
  • Charge Protocol: Initial capacity evaluation should be performed at a constant 0.2C (7 A) charge rate to the nominal 3.6 V potential.

This procedure outlines the safe initialization and cycling of the cell for laboratory testing. Follow these steps to prevent damage and ensure data reproducibility.

Required Equipment: Battery Cycler, Battery Management System

  1. Visual Inspection
    Inspect the pouch cell for any signs of swelling, puncture, or terminal corrosion before handling.
  2. Electrical Connection
    Connect the cell terminals to the battery cycler using cables rated for at least 105 A continuous current.
  3. Initial Charge
    Charge the cell at a constant current of 7 A (0.2C) until the voltage reaches 3.6 V to establish nominal charge.
  4. Discharge Limitation
    Set the cycler to limit discharge current to 105 A (3.0C) and avoid exceeding 175 A (5.0C) pulse duration.

How does the silicon oxide anode content affect cycle life at 3.0C continuous discharge compared to standard graphite-only NMC pouch cells?

The SiOx blend boosts gravimetric density beyond 310 Wh/kg but introduces volumetric expansion stress during cycling. At the rated 3.0C continuous discharge, the cell maintains structural particle integrity, though cycle life may be reduced relative to pure graphite anodes due to silicon's inherent volume change; the product description does not specify cycle life figures, so quantitative comparison is not possible from the provided data.

Can this 35 Ah pouch cell be integrated directly into an existing 48V EV prototype battery pack without modifying the BMS voltage thresholds?

Yes, the cell's 2.50 V to 4.25 V operating window is compatible with standard 48V pack architectures when configured in a 12-series string (43.2 V nominal). However, the BMS must support a maximum charge voltage of 4.25 V per cell and a 2.0C charge rate; the low 1.6 mΩ internal resistance minimizes balancing overhead, but the pack designer must verify thermal management for the 3.0C continuous discharge limit.

What are the mandatory storage and handling conditions to prevent lithium plating or electrolyte leakage in this flexible laminate pouch cell?

Store at 50% state of charge in a dry, temperature-controlled environment between 0 °C and +45 °C to avoid lithium plating during storage. The flexible multi-layer aluminum laminate enclosure requires protection from puncture and compressive forces; do not stack cells without rigid separators, and avoid charging below 0 °C as specified by the thermal charging scope window.

This 35 Ah NMC/Gr+SiOx pouch cell delivers 310 Wh/kg and >700 Wh/L, with a low 1.6 mΩ internal resistance and support for 3C continuous discharge, making it suitable for EV prototype pack testing, though charging is limited to 2C and prohibited below 0°C.

Positive

  • High gravimetric and volumetric density: The cell achieves an elite gravimetric density above 310 Wh/kg and a volumetric rating exceeding 700 Wh/L, enabling maximum energy storage in compact form factors for vehicle and stationary applications.
  • Robust high-rate discharge capability: Supports continuous 3.0C and transient 5.0C pulse discharge currents, validated at ≥30% SOC, making it suitable for demanding EV prototype battery pack testing sequences.

Trade-offs

  • Restricted low-temperature charging: Charging is not permitted below 0 °C, limiting use in cold environments unless thermal management is provided.
  • Limited maximum charge current: The maximum continuous charge current is 2.0C, which may constrain applications requiring faster charging rates.
