Abstract

Abstract: The nine-dimensional model proposed in this paper systematically characterizes the features of fire and explosion risk of lithium battery from the aspects of technology ontology, disaster energy, risk receptors, and management. The model is used to evaluate the disaster risk of three main application areas of lithium battery, namely mobile phone, electric bicycle, and electric vehicle. The fire and explosion risk caused by lithium battery in electric bicycle is found to be the highest. By analyzing the disaster procedure of lithium battery, some safety prevention measures are proposed from technical ontology constraints, risk causing energy control, energy release path shielding, and risk receptor protection respectively. The results provide support for the safety management of lithium battery technology, and also provide ideas for risk analysis and control of other new energy technologies.
