碩士 === 國立雲林科技大學 === 環境與安全衛生工程系 === 103 === Since the enhancement of technology and environmental awareness, people have more concerned about the development of rechargeable Li-ion battery. Broadly used batteries are nickel-cadmium battery (Ni-Cd), nickel-hydrogen battery (Ni-MN), lithium-ion battery (LIB). Furthermore, the currently common used lithium-ion polymer battery (LIPB), which is generally referred to as “polymer lithium batteries” and is widely used to consumer electronics, such as notebook, smart phone, and digital camera. Therefore, the main experimental method was conducted by using an adiabatic calorimeter, vent sizing package 2 (VSP2), to identify thermal runaway of various state-of-charges (SOCs) on LIPB. Changes in temperature and pressure of lithium-ion polymer batteries under adiabatic measurements, and the thermokinetic parameters, such as apparent onset temperature (T0), maximum temperature (Tmax), maximum pressure (Pmax), self-heating rate (dT dt–1), and pressure rise rate (dP dt–1). In addition, the experimental results can be analyzed the thermal response of LIPB and thermal runaway characteristics. The safety considerations are to provide a reference for the design and planning of security of LIPB.
