Application Fit & Sizing Matrix

Operational Limits
pressure: Atmospheric (sealed cell, no external pressure variation)
other spec: Charge/discharge rate: 0.5C to 2C typical, Depth of Discharge: 80-90% recommended
temperature: -20°C to 60°C (operational), 0°C to 45°C (optimal charging)
Media Compatibility
✓ Lithium-ion chemistry (LiCoO2 cathode) ✓ Graphite anode materials ✓ Organic electrolyte solutions (LiPF6 in EC/DMC)
Unsuitable: High humidity/water immersion environments (risk of short circuit and thermal runaway)
Sizing Data Required
  • Required battery capacity (mAh)
  • Maximum continuous discharge current (A)
  • Physical dimensions/volume constraints (mm³)

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Thermal Runaway
Cause: Internal short circuit, overcharging, or external heat leading to uncontrolled temperature increase and potential combustion.
Capacity Fade
Cause: Electrode degradation, electrolyte decomposition, or solid-electrolyte interphase (SEI) layer growth over charge cycles.
Maintenance Indicators
