Maximum temperature of lithium battery pack during operation

What temperature should a lithium battery be stored?

Proper storage of lithium batteries is crucial for preserving their performance and extending their lifespan. When not in use, experts recommend storing lithium batteries within a temperature range of -20°C to 25°C (-4°F to 77°F).

How hot can a lithium battery be?

Lithium batteries are designed to operate safely within a temperature range of 0°C to 60°C (32°F to 140°F). While they can withstand temperatures up to 60°C, prolonged exposure to high temperatures can accelerate aging, decrease capacity, and increase the risk of thermal runaway—a condition where the battery overheats uncontrollably.

How does temperature affect lithium battery performance?

Understanding lithium battery temperature range helps predict performance drop at low temperatures. Li-ion batteries may show up to 30% capacity loss below 0°C (32°F). In cold temperatures, like below 15°C (59°F), lithium batteries experience reduced performance. Chemical reactions within the battery slow down, causing decreased power output.

Why is high temperature a hazard for lithium batteries?

Similarly, high temperature is a life killer and safety hazard for lithium batteries. High temperature will sharply accelerate battery aging and capacity decay, and is also the main cause of battery bulging and even fire. The energy storage and release of lithium batteries rely on chemical reactions at the positive and negative electrodes.

What temperature should a battery be stored at?

Max 60°C: Continuous high temperature use will accelerate battery aging and capacity decay. If the temperature exceeds 70°C, the risk of thermal runaway will increase dramatically. Ideal long-term storage: A cool, dry, stable environment around 15°C (59°F) is recommended.

How should lithium batteries be stored?

For optimal storage conditions, lithium batteries should be kept in: Cool, Dry Places: Ideally at temperatures between 20°C and 25°C (68°F and 77°F). Low Humidity: Avoid damp environments that can cause corrosion. Partial Charge: Store batteries at about 40% charge capacity to minimize stress on the cells.
