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.
These constraints define safe operational boundaries for the ES02 solid-state cell to prevent degradation and ensure safety. Adherence to voltage, temperature, and discharge limits is critical for maintaining cell integrity and preventing failure.
- Voltage Limit: Operate cells only within the voltage limits of 2.5V to 4.25V to avoid damage.
- Temperature Range: Maintain cell temperature between -20°C and 60°C during operation to ensure thermal stability.
- Discharge Rate: Do not exceed continuous discharge rate of 2C to prevent overheating and capacity loss.
- Short Circuit Prevention: Handle with care to prevent short circuits, as cells have low internal resistance of ≤2.5mΩ.
How does the 390-400 Wh/kg energy density of the ES02 series translate into real-world flight time trade-offs versus conventional Li-polymer UAV batteries?
The ES02 series delivers a 390-400 Wh/kg specific energy, which is significantly higher than typical Li-polymer pouch cells used in UAVs, enabling record-breaking mission endurance for patrol and surveying. However, this ultra-high energy density comes with a continuous discharge rate of 2C at ≥90% SOC and a cycle life of only 300 cycles at 1C/1C, meaning operators must trade peak endurance for reduced high-rate discharge capability and shorter overall lifespan compared to lower-energy-density cells.
Can the ES02 solid-state cells be integrated into existing UAV battery management systems designed for Li-polymer batteries?
Integration requires careful BMS reconfiguration because the ES02 cells operate at a nominal voltage of 3.44V with a voltage range of 2.5V to 4.25V, which differs from standard Li-polymer chemistries. The low AC internal resistance of ≤2.5mΩ at 30% SOC also demands updated current sensing and balancing algorithms to prevent overcurrent stress during sustained 2C discharge.
What are the critical handling and storage requirements for the ES02 solid-state cells to maintain safety and performance?
The ES02 cells must be operated within -20°C to 60°C to avoid thermal runaway or capacity fade, and storage should follow standard solid-state protocols to prevent mechanical damage to the rigid cell casing. The cells have dimensions of 10.5mm x 87mm x 187mm (39Ah model) and 10.7mm x 122mm x 175mm (53Ah model), requiring secure mounting in UAV frames to avoid vibration-induced stress on the solid electrolyte interface.
The ES02 series solid-state cells deliver industry-leading 390-400 Wh/kg energy density for extended UAV endurance, but limited cycle life of 300 cycles and a voltage range extending to 4.25V require careful system integration.
Positive
- Ultra-High Energy Density (390-400 Wh/kg): Provides record-breaking specific energy of up to 400 Wh/kg, enabling extended flight times for long-endurance UAV missions without sacrificing payload capacity.
- Low Internal Resistance (≤2.5 mΩ): AC internal resistance of ≤2.5 mΩ at 30% SOC minimizes heat generation during sustained discharge, improving power delivery efficiency and thermal management.
Trade-offs
- Limited Cycle Life (300 cycles at 1C/1C): Rated for only 300 cycles at room temperature with 1C charge/discharge, which is lower than typical lithium-ion chemistries and may require more frequent replacement in high-usage scenarios.
- Non-Standard Voltage Range (up to 4.25V): Upper voltage limit of 4.25V exceeds the common 4.2V cutoff, necessitating compatible battery management systems and charging infrastructure to avoid overvoltage or reduced cycle life.
