Lithium-ion battery safety: maximum temperature exposure?

Lithium-ion battery safety: maximum temperature exposure?

• A. 150 degrees
• B. 160 degrees
• C. 170 degrees
• D. 180 degrees

Answer: (B)

High temperatures accelerate the chemical reactions inside lithium-ion cells, causing electrolyte decomposition, gas buildup, and pressure rise. If heat exposure goes beyond what the battery’s safety design can handle, the risk of thermal runaway—and potentially fire or explosion—increases dramatically. A maximum exposure temperature is set to keep the cell within those safe design margins; pushing past that point compromises safety. Among typical safety thresholds, the value that represents the upper limit of safe exposure is the one in the mid-to-high range of the options, while the lower value stays below the limit and the higher values exceed it. So the maximum safe exposure is 160 degrees Celsius.
