● Extreme Condition Simulation & Big Data Analysis
(1) Multi-Dimensional Test Matrix:
① Power Characteristics: 100A transient charge/discharge + EIS spectrum analysis.
② Environmental Adaptability: Temperature-controlled cycling chambers (-40°C to 120°C) + multi-axis vibration testers.
③ Life Prediction: Aging models based on current surge/temperature/voltage stress.
(2) Smart Data Hub: (Implies data aggregation and analysis capabilities)
● Seamless Pilot Line Translation
(1) Process parameters of supercapacitor lab line are consistent with production lines (e.g., adjustable coating speed 0.5-5 m/min, calendering density deviation ≤1.5%).
(2) Modular design supports upgrade to pilot line (e.g., winding machine → high-speed winding, manual filling → vacuum filling).

Actionable insights from planning to execution
● Goal Difference: Capacitors focus on power density/cycle life, batteries focus on energy density/safety.
● Process Difference: No need for formation/aging, but requires higher precision coating (prevent dendrites) and low-impedance sealing.
● Testing Focus: Pulse testing (≥50C), EIS spectrum analysis, self-discharge rate monitoring.
● Use 4-wire Kelvin method to eliminate contact resistance.
● Test system integrates liquid cooling modules (ΔT≤2°C).
● Multi-stage fuse protection (response time <1ms).
Yes! Via:
● Precision slot-die coating (min. coating width 5mm).
● Laser patterning and cutting (precision ±10μm).
● Low-temperature sealing process (≤80°C).
We can supply:
● Specialty activated carbon (BET 1800-2200 m²/g).
● Ionic liquid electrolytes (withstand voltage ≥4V).
● Single-walled carbon nanotubes (conductive agent).
● Process parameter mapping (e.g., coating speed/pressure vs. density correlations).
● Shared material database (batch consistency analysis).
● CPK (Process Capability Index) analysis reports.
