Part 1: Temperature Challenges

1.1 Battery Performance in Extreme Temperature

You face significant challenges when deploying lithium-ion batteries in environments with temperature extremes. At -40°C, the electrolyte inside the battery can solidify, which increases internal resistance and causes capacity to drop to as low as 10%-20% of normal. In these conditions, lithium-ion cells may retain only 57% of their capacity compared to room temperature. High temperatures above 60°C accelerate electrolyte decomposition, which can trigger thermal runaway and even explosions due to increased internal pressure and the collapse of the solid electrolyte interface (SEI). Prolonged exposure to high temperatures also accelerates battery aging, increases internal resistance, and reduces both capacity and cycle life.

• At low temperatures:

  • Electrolyte solidifies, raising resistance.

  • Capacity drops sharply.

  • Charging can cause lithium plating, increasing safety risks.

• At high temperatures:

  • Electrolyte decomposes, risking thermal runaway.

  • SEI layer collapses, reducing battery performance.

  • Long-term exposure between 45–60°C can cut battery lifespan by up to 40%.

You must select lithium-ion batteries engineered for high temperature stability and cold weather performance to ensure reliable operation in outdoor security cameras and sensors.

1.2 Effects on Outdoor Security Cameras

Outdoor security cameras rely on stable battery performance to deliver uninterrupted surveillance. Extreme temperatures can cause voltage control problems, leading to malfunctions or shutdowns.

In contrast, alkaline batteries often suffer from voltage drops, resulting in system failures.

Tip: Install cameras in shaded or ventilated areas and avoid direct sunlight to protect battery packs from overheating.

Common battery failure modes in outdoor security cameras include swelling, deformation, and rapid capacity loss. Charging lithium-ion batteries in cold conditions can lead to lithium plating, which increases the risk of short-circuiting. High temperatures erode battery capacity and increase the risk of thermal runaway, especially above 60°C. You should regularly check battery voltage and look for signs of overheating to mitigate safety risks.

Temperature resilience remains essential for outdoor security cameras and sensors. By choosing lithium-ion batteries designed for the optimal temperature range, you ensure consistent performance and minimize downtime in your security system battery solution.
