Researcher T.J

T.J. | Researcher, Sensloop Lab I focus on electric vehicle battery safety, embedded systems, and field-oriented engineering development. Sensloop Lab is a research log that documents real experiments and data, including battery analysis, repair records, charge–discharge characteristics, and sensor-based control system development. I am currently involved in product development and commercialization in the fire safety and protection equipment industry. My work includes designing embedded control and data acquisition systems based on Arduino, ESP32, and Raspberry Pi platforms. In addition, I study lithium-ion battery behavior such as internal resistance, performance characteristics, and thermal runaway mechanisms to provide practical engineering insights. This blog aims to: Share experiment-based technical knowledge Build a battery and energy data archive Document embedded and hardware development cases Provide practical resources for engineers and field researchers Sensloop Lab is built on verification, measurement, and repeatable engineering practice.

Lithium-Ion Thermal Runaway: Fire Mechanism Explained

Battery fire initiation thermal runaway process

💡 Research Overview Lithium-ion battery thermal runaway is the primary failure mechanism behind most EV battery fires and large-scale ESS incidents. Although such events are often described as “explosions,” the internal process is more accurately defined as a self-accelerating exothermic reaction sequence. Within seconds, heat accumulation triggers electrolyte decomposition, oxygen release from cathode materials (NCM/NCA), … Read more
