Abstract
This study is to analyze the explosion and fire risks due to high temperature and short circuit current of Lithium batteries. This study selected the typical types of Li-polymer batteries and Li-ion batteries as the test samples. The result of explosion risk assessment due to the high temperature showed that, while a Li-polymer battery had $170^{\circ}C$ explosion on average, a Li-ion battery had $187^{\circ}C$ explosion. The measurement result of temperature increase due to short circuit current revealed that, in case that protection circuit module (PCM) was normally working, there was little of temperature increase due to over-current limitation. However, in case that PCM was out of order, the temperature of a Li-polymer battery increased up to an average of $115.7^{\circ}C$ and the temperature of a Li-ion battery increased up to an average of $80.5^{\circ}C$, which showed the higher risks of fire and burn.
