Quick Answer
Lithium battery hazards are caused by a combination of environmental factors including high temperatures, moisture, physical stress, and electrical overload, which can lead to thermal runaway and subsequent fires or explosions.
Environmental Exposure Risks
High temperatures are a significant contributor to lithium battery hazards. For lithium-ion batteries, temperatures above 130°F (54°C) can cause a rapid increase in internal pressure, leading to potential failure. In extreme cases, temperatures above 140°F (60°C) can cause thermal runaway, resulting in fire or explosion.
Moisture and Humidity
Moisture and humidity also pose a significant risk to lithium batteries. Water can seep into the battery’s internal components, causing a short circuit and potentially triggering thermal runaway. In coastal or high-humidity environments, it’s essential to take extra precautions to protect batteries from moisture. This can be achieved through the use of protective coatings, sealed enclosures, or desiccant packs.
Physical Stress and Handling
Physical stress and improper handling can also lead to lithium battery hazards. Drops, impacts, or crushing can cause internal damage to the battery, leading to potential failure. When handling lithium batteries, it’s essential to follow proper safety procedures, including wearing protective gear and using tools to prevent physical stress. Regular inspections and maintenance can also help identify potential issues before they become critical.
