Accessories & Customization
Yes. We offer customization for thickness, width, and height to fit your specific chassis or battery pack design. Support for 48V, 60V, and 72V system configurations is available.Technical Recommendation:
For optimal performance and safety, we recommend pairing these cells with a BMS that supports high-precision balancing to maximize the solid-state lifespan.
Store cells between -20°C and 55°C to maintain electrochemical stability and prevent capacity fade. Avoid exposure to moisture, conductive debris, and mechanical punctures to mitigate short circuit and thermal runaway risks.
- Temperature Range: Operating and storage temperature must remain within -20°C to 55°C to prevent electrolyte degradation and internal short circuits.
- Moisture Sensitivity: Pouch cells must be kept in dry environments to avoid moisture ingress that can cause lithium metal corrosion and gas evolution.
- Mechanical Integrity: Inspect for punctures, dents, or swelling before use, as mechanical damage can compromise the solid electrolyte separator and lead to internal short circuits.
- Electrical Safety: Never short-circuit the terminals; use insulated tools and avoid contact with conductive surfaces to prevent high-current discharge and thermal runaway.
- Voltage Limits: Charge only within the manufacturer's specified voltage range to prevent overcharge-induced lithium plating and overdischarge-induced copper dissolution.
Follow these steps to safely inspect, prepare, and install the ZC series pouch cell into an e-bike battery pack. Proper handling ensures safety and longevity of the cell.
Required Equipment: Insulated gloves, Digital multimeter, Non-conductive work surface
- Inspect the Cell
Inspect the pouch cell for any visible damage, swelling, or electrolyte leakage before handling. - Measure Voltage
Measure the open circuit voltage using a digital multimeter to confirm it is within safe operating range. - Prepare the Battery Compartment
Ensure the battery compartment is clean, dry, and free of conductive debris before inserting the cell. - Connect the Cell
Align the cell terminals with the correct polarity and connect to the battery management system (BMS) using insulated connectors. - Secure and Test
Secure the cell in the compartment and perform a functional test to verify proper connection and voltage output.
How does the 3C continuous discharge rate of the ZC series solid-state pouch cell affect cycle life under high-load e-bike swapping conditions?
The ZC series maintains a cycle life of ≥2000 cycles at room temperature even at a 3C continuous discharge rate, which is specified for all three models (20Ah, 39Ah, 29Ah). This high-rate capability is enabled by the composite manganese-based cathode (LMO + LMFP) and high-rate graphite anode, ensuring reliable torque for heavy loads and steep inclines without compromising the 1800+ deep-cycle longevity required for battery swapping infrastructure.
Can the ZC122175-20 solid-state pouch cell be integrated into an existing 48V e-bike battery pack with a standard BMS, or does it require a specific balancing system?
Integration requires a BMS that supports high-precision balancing to maximize the solid-state lifespan, as recommended in the product documentation. The cell has a nominal voltage of 3.8V and supports 48V, 60V, and 72V system configurations, but standard BMS units without precision balancing may not fully exploit the ≥2000-cycle capability. Custom dimensions for thickness, width, and height are available to fit specific chassis designs.
What are the storage and handling requirements for the ZC series solid-state pouch cells to maintain performance over 2000 cycles?
The cells must be stored and operated within the specified temperature range of -20°C to 55°C to preserve cycle life and safety. The proprietary electrolyte coating and solid-state design provide superior stability compared to traditional power solutions, but exposure to temperatures outside this range can degrade the composite manganese-based cathode (LMO + LMFP) and reduce longevity. For bulk storage, maintain ambient conditions within this window and use a compatible BMS with high-precision balancing.
The ZC series solid-state pouch cells deliver outstanding cycle life exceeding 2000 cycles and a 3C continuous discharge rate suitable for e-bike swapping applications, but require a high-precision BMS for optimal longevity and may need custom dimensional adaptation for specific chassis designs.
Positive
- Exceptional Cycle Life Over 2000 Cycles: Delivers over 2000 cycles at room temperature, triple the longevity of lead-acid batteries, significantly lowering total cost of ownership for high-utilization e-bike fleets.
- High Continuous Discharge Rate of 3C: With a 3C continuous discharge capability, the cells provide reliable torque for heavy loads and steep inclines, enabling sustained high-power operation in demanding e-bike conditions.
Trade-offs
- Requires High-Precision BMS for Longevity: Optimal cell lifespan and safety depend on pairing with a BMS that supports high-precision balancing; standard or basic BMS may not fully realize the 2000-cycle potential.
- Standard Dimensions May Require Custom Fit: The off-the-shelf pouch dimensions (e.g., 9.5×122×175 mm for the 20Ah variant) may not fit existing battery compartments, necessitating custom thickness, width, or height adjustments for certain chassis designs.
