Accessories & Customization
Solid-State Advantage: Superior thermal safety and volumetric efficiency compared to traditional Li-polymer pouch cells.
Internal Resistance: Low IR design (≤2.5mΩ) ensures minimal heat generation during sustained flight operations.
Custom Solutions: Specialized cell dimensions and tab configurations are available for research-grade prototyping and industrial scaling.
The ES02 series solid-state cells require strict adherence to the specified voltage window of 2.5V to 4.25V and operating temperature range of -20°C to 60°C. Exceeding these limits may lead to irreversible cell damage or safety hazards.
- Voltage Window: Maintain cell voltage between 2.5V and 4.25V to avoid over-discharge or overcharge conditions.
- Operating Temperature Range: Operate the cell within -20°C to 60°C to ensure thermal stability and prevent degradation.
How do the 390Wh/kg and 395Wh/kg variants of the ES02 series differ in terms of capacity and physical dimensions for UAV integration?
The ES02 series offers two variants: the ES0287187T1-39 with 39Ah capacity and 390Wh/kg energy density (10.5×87×187 mm), and the ES02122175T1-53 with 53Ah capacity and 395Wh/kg energy density (10.7×122×175 mm). Both operate at 3.44V nominal voltage and share the same voltage range (2.5–4.25V), internal resistance (≤2.5mΩ at 30% SOC), and 2C continuous discharge capability with ≥90% SOC retention. The trade-off is higher capacity and slightly higher energy density in the larger 53Ah cell versus a more compact footprint for the 39Ah cell.
What are the voltage, discharge rate, and temperature constraints for integrating these solid-state cells into a high-end UAV power system?
The ES02 cells operate at a nominal voltage of 3.44V with a voltage range of 2.5V to 4.25V. They support a continuous discharge rate of 2C with ≥90% state-of-charge retention, and a cycle life of ≥300 cycles at room temperature under 1C/1C charge/discharge. The safe operating temperature range is -20°C to 60°C, ensuring stable performance in extreme flight conditions. The low internal resistance (≤2.5mΩ) minimizes heat generation during sustained discharge.
What handling, safety, or infrastructure requirements are critical for these solid-state UAV batteries compared to conventional Li-polymer cells?
The ES02 series leverages solid-state architecture for superior thermal safety and volumetric efficiency over traditional Li-polymer pouch cells. The operating temperature range (-20°C to 60°C) and low internal resistance (≤2.5mΩ) reduce thermal runaway risk during high-rate discharge. No specialized liquid electrolyte handling is required, but the cells should be used within the specified voltage limits (2.5–4.25V) and charge/discharge rates to maintain cycle life (≥300 cycles at 1C/1C). Custom tab configurations are available for research-grade integration.
The ES02 series solid-state cells provide 390–400 Wh/kg energy density with ≥90% SOC retention at 2C continuous discharge, but are constrained to a cycle life of only 300 cycles (1C/1C) and a maximum 2C discharge rate.
Positive
- Ultra-high energy density: 390–400 Wh/kg specific energy enables extended UAV flight times and maximizes payload efficiency for long-endurance missions.
- Stable high-rate output: Maintains ≥90% SOC at 2C continuous discharge, ensuring reliable power delivery during sustained flight operations.
Trade-offs
- Limited cycle life: Rated for only ≥300 cycles at 1C/1C charge/discharge, which may be insufficient for applications requiring frequent deep cycling.
- Moderate discharge rate cap: Maximum continuous discharge is 2C, restricting suitability for high-current-demand UAV platforms or aggressive flight profiles.
