Unsuitable: Saltwater immersion or high-chloride environments (accelerates corrosion)
Sizing Data Required
  • Required energy capacity (kWh)
  • Peak power demand (kW) and C-rate
  • Available installation space/volume constraints

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Thermal runaway
Cause: Internal short circuit due to dendrite formation, manufacturing defects, or mechanical damage leading to uncontrolled exothermic reactions and temperature escalation.
Capacity degradation
Cause: Solid electrolyte interface (SEI) layer growth, lithium plating, or active material loss from repeated charge/discharge cycles and extreme operating temperatures.
Maintenance Indicators
  • Visible swelling or deformation of cell/module casing indicating gas generation or internal pressure buildup
  • Abnormal temperature rise detected via thermal imaging or sensors during operation/charging, accompanied by unusual odor
Engineering Tips
  • Implement strict temperature management: maintain operating range between 15-35°C using active cooling/heating systems and avoid exposure to thermal extremes
  • Optimize charging protocols: use CC-CV charging with voltage/current limits, avoid continuous high-rate charging/discharging, and maintain state-of-charge between 20-80% for storage
