Charge voltage must be limited to 3.95V per cell to prevent overcharge degradation. Continuous discharge current should not exceed 150A (3C) to maintain thermal stability.

  • Storage Constraint: Store the battery in a dry, non-conductive enclosure to avoid external short circuits.

Follow these steps to safely initialize the semi-solid battery for first use. Adherence to the charge and discharge limits ensures long cycle life.

Required Equipment: Lithium-ion battery charger with CC-CV profile, Insulated gloves and safety goggles

  1. Inspect battery
    Inspect the pouch cell for any swelling, puncture, or leakage before handling.
  2. Connect charger
    Connect the charger leads to the battery terminals with correct polarity.
  3. Set charging parameters
    Set the charger to constant current 50A (1C) with a constant voltage limit of 3.95V per cell.
  4. Monitor charge completion
    Allow the battery to charge until the current tapers to 10% of the set current.
  5. Verify voltage
    Verify the open circuit voltage reaches 3.95V before disconnecting the charger.

How does the 300 Wh/kg energy density of the semi-solid battery affect thermal management under 5C peak discharge?

The 300 Wh/kg energy density combined with a 5C peak discharge rate generates significant internal heat, but the semi-solid electrolyte improves thermal stability and reduces leakage risk compared to liquid electrolytes. The pouch cell format and specified dimensions (e.g., 211.5 × 108 × 250 mm for the 18S model) provide a large surface area for passive heat dissipation, though active cooling may be required for sustained peak loads in enclosed systems.

Can the 3.95V 50Ah semi-solid battery be integrated directly into existing drone power systems designed for standard LiPo packs?

Direct integration requires verifying voltage compatibility, as the nominal 3.95V per cell differs from typical LiPo (3.7V) or Li-ion (3.6V) chemistries, potentially affecting BMS cutoffs and charger settings. The 1C charge and 3C continuous discharge rates are compatible with many high-power drone ESCs, but the physical dimensions (e.g., 72.5 × 108 × 250 mm for the 6S model) and weight (4150 g) must fit the airframe without exceeding payload limits.

What are the storage and handling requirements for semi-solid electrolyte pouch cells to prevent performance degradation?

Semi-solid electrolyte cells should be stored at partial state of charge (around 40-60%) in a cool, dry environment below 25°C to minimize self-discharge and electrolyte aging. The pouch cell construction requires protection from physical puncture and compression, as the semi-solid electrolyte, while reducing leakage risk, can still be damaged by excessive force or sharp objects. Avoid exposure to temperatures above 60°C or below -20°C to maintain the 300 Wh/kg energy density and cycle life.

This 50Ah semi-solid pouch cell series provides 300 Wh/kg energy density and 3C continuous discharge, making it suitable for lightweight drone and robotics applications, though the 1C charge limit and restricted series options may require careful system integration.

Positive

  • Ultra-High Energy Density: Achieves 300 Wh/kg, enabling extreme lightweight design for UAVs and portable devices by reducing overall battery mass for a given energy capacity.
  • High Rate Capability: Supports 1C charge with 3C continuous and 5C peak discharge, providing stable power output for demanding applications such as high-performance drones and robotics.

Trade-offs

  • Maximum Charge Rate of 1C: The 1C maximum charge rate may limit applications requiring faster recharging cycles, such as high-duty-cycle robotics or rapid-turnaround UAV operations.
  • Limited Series Configurations: Only 6S, 8S, 12S, and 18S configurations are offered, which may not accommodate all voltage requirements without custom assembly or additional cells.
