Accessories & Customization
BMS Integration: Optimized for smart management systems requiring precise high-rate discharge monitoring and thermal control.
Custom Form Factors: Bespoke cell dimensions and tab orientations are available for specialized research and industrial integration.
Technical Data: Full discharge curve sets and safety testing documentation are available upon verified inquiry.
The solid-state cell must be operated within -20°C to 60°C to ensure performance and safety. The cell is sensitive to mechanical deformation and conductive contamination.
- Temperature Range: Operate the cell only within the specified temperature range of -20°C to 60°C.
- Mechanical Integrity: Avoid puncturing, crushing, or deforming the cell to prevent internal short circuits.
- Electrical Safety: Prevent external short circuits by keeping terminals isolated from conductive materials.
The ES03 series solid-state cell requires careful handling to prevent electrical shorts and mechanical damage. Follow these steps for safe integration into a UAV or robotic system.
- Inspect for Damage
Inspect the cell for any physical damage, swelling, or leakage before handling. - Verify Voltage
Measure the cell's open-circuit voltage to confirm it matches the nominal 3.54V specification. - Connect to BMS
Connect the cell to a compatible battery management system following the manufacturer's wiring instructions.
How does the ES03 series balance 340 Wh/kg energy density with 3C continuous discharge without compromising cycle life?
The ES03 series achieves this balance through an optimized solid-state architecture that maintains ultra-low internal resistance of ≤1 mΩ at 30% SOC, minimizing energy loss during high-rate discharge. This design enables 3C continuous discharge at ≥95% SOC while retaining a cycle life of ≥500 cycles at 1C/3C under room temperature, with a temperature rise of less than 30°C to preserve long-term cell health.
Can the ES0387187T1-36 or ES0387187T2-39 cells be integrated into existing UAV battery management systems designed for lithium-ion packs?
Yes, the ES03 series is optimized for BMS integration requiring precise high-rate discharge monitoring and thermal control, but the BMS must be configured for the cells' nominal voltage of 3.54V and continuous 3C discharge profile. The cells have a nominal capacity of 36Ah or 39Ah and dimensions of 10.5×87×187 mm or 11.5×87×187 mm, which may require mechanical adaptation for existing UAV battery bays.
What are the storage and handling requirements for the ES03 series solid-state cells to maintain performance and safety?
The ES03 cells must be stored and operated within the specified temperature range of -20°C to 60°C to prevent degradation of the solid-state electrolyte and maintain cycle life. Handling should avoid mechanical stress on the prismatic form factor (10.5–11.5 mm thickness), and cells should be kept at recommended SOC levels to preserve the ≤1 mΩ internal resistance characteristic.
The ES03 series solid-state cells deliver a rare combination of 340 Wh/kg energy density and 3 C continuous discharge with ≤1 mΩ internal resistance, limiting temperature rise to under 30 °C. These prismatic cells (two capacities: 36 Ah and 39 Ah) require a sophisticated BMS for high-rate monitoring and have fixed dimensions that may necessitate custom mechanical integration in non-standard battery packs.
Positive
- Balanced high energy and power density: The 340 Wh/kg energy density combined with a 3 C discharge rate allows the cell to serve both capacity-intensive and power-demanding applications without severe compromise.
- Ultra-low internal resistance reduces losses: An AC internal resistance of ≤1 mΩ minimizes ohmic heating and energy dissipation during high-rate discharge, improving overall system efficiency and thermal stability.
Trade-offs
- Requires precise BMS integration: The cell's high-rate discharge and thermal characteristics demand a smart battery management system capable of accurate current monitoring and thermal control, increasing system complexity.
- Specific cell dimensions limit packing flexibility: The fixed prismatic form factors of 10.5×87×187 mm or 11.5×87×187 mm may require custom enclosures or adapters for integration into non‑standard battery assemblies.
