There’s a lot of misinformation floating around about lithium-ion batteries, so let’s set the record straight. The 18650 cells, which are the same ones used in the 2024 @Tesla Model S and X, use Nickel-Cobalt-Aluminum (NCA) cathode chemistry and are incredibly stable. While failures can happen under extreme conditions, data shows that thermal runaway doesn’t typically begin until approximately 262°C, not 150°C as often claimed. Under normal conditions, these batteries are safe, reliable, and efficient. In our test video, the 18650 cells used had already undergone significant abuse, including rapid discharge and recharging cycles, physical damage from dropping, and even being hit with a hammer. These cells were also tested without a Battery Management System (BMS), meaning there was no regulation of their temperature or voltage, another layer of safety that is standard in real-world applications. Despite this extreme treatment, thermal runaway only occurred just north of 150°C, further proving how resilient these batteries are under normal use conditions. Too often, conclusions about lithium-ion safety are based on fear rather than facts. While no energy storage system is risk-free, we need data-driven conclusions, not emotional reactions. This is why we conduct real-world burn tests: to understand the risks factually and improve safety strategies for first responders. We have forgotten that petroleum-based fuels went through the exact same scrutiny when they were first introduced. The concerns about explosions, handling risks, and overall safety were everywhere, but over time, with rigorous testing and safety advancements, they became the standard. We’re seeing the same process happen with lithium-ion technology today. Instead of jumping to conclusions, we need to focus on measured analysis, real-world testing, and factual discussions. The industry needs education, not fear-driven narratives. Check out this burn test and see for yourself how these batteries actually behave. Let’s push for better solutions, better safety, and conversations based on science, not speculation. *This video was taken in CESATs newest research lab while setting up some new heat detection systems.
