The impact of Temperature on battery lifetime for Energy Storage Systems and Performance”
by Kareem Khalaf Ali (IOP Conf. Series, 2025) ResearchGate
Why it’s useful
- It examines how charging / discharging cycles affect battery temperature, and in turn how temperature affects discharge capacity and battery lifetime. ResearchGate
- It considers multiple battery chemistries (Li-ion, NiCd, FePO) across a temperature range of 10 °C to 60 °C. ResearchGate
- It finds that battery temperature increases approximately linearly with discharge current, and that the discharge capacity has a polynomial (cubic) relation with temperature. ResearchGate
- It identifies an optimal operating temperature window (roughly 16 °C to 27 °C) beyond which performance and lifetime degrade. ResearchGate
- It points out that even storing a battery at temperatures above ~25 °C can have negative impacts on long-term life. ResearchGate
Takeaway for battery-inverter systems: This paper bridges lab data and real-world energy storage systems, showing how temperature management is key in ensuring that your battery bank remains healthy, efficient, and long lived.

🧠 Key Insights & Considerations for Battery + Inverter Systems
Drawing from these works, here are some crucial points you’ll want to emphasize (or check) in your article:
- Temperature accelerates degradation
Higher temperatures increase reaction rates and side reactions inside the battery (e.g. electrolyte decomposition, active-material loss), which reduce cycle life. Even moderate increases above ~25 °C can harm longevity. MDPI+3ResearchGate+3ScienceDirect+3 - Low temperatures hurt performance (but less damaging long-term)
At lower temperatures, internal resistance rises, slowing ion transport and reducing effective capacity. It may hamper charging/discharging, especially at high currents. ScienceDirect+2ResearchGate+2 - Optimal temperature “sweet spot”
The IOP article suggests ~16 °C to 27 °C is favorable. Operating outside that (especially above) begins to incur trade-offs. ResearchGate - Thermal runaway / safety risks
In hot conditions, runaway reactions or thermal instability are more likely if a battery is stressed (e.g. via fast charge). Good thermal management is essential. ScienceDirect+1 - Thermal management is critical
— Use cooling (air, liquid, phase-change materials) or design enclosures with passive/active heat dissipation. ScienceDirect
— Uniform temperature distribution matters (hot spots are worse than uniform moderate heating). ScienceDirect+1
— Inverter installations should avoid direct sun or hot enclosures, allow ventilation, and consider derating curves. Sunflx丨China Solar Inverter Manufacture - Battery / inverter interaction
The inverter may produce heat, adding to ambient temperature stress on nearby batteries. Also, inverter derating (lower output when hot) affects system design. Sunflx丨China Solar Inverter Manufacture+1 - Modeling & control strategies
Advanced systems treat battery temperature as a state variable. They can adjust charge/discharge currents or cooling to optimize life vs. performance trade-off. arXiv+1
