Development of a fixable model for the reliability and safety evaluation of the components of a commercial lithium-ion battery

In recent years, efforts and attention are gradually been shifted to the pollution-free renewable energy (fuel cell and lithium-ion battery), for propelling vehicles and for rural and urban electrification. With the advancement of these renewable energies, it is only necessary to continuously explore their behaviour, reliability, and safety. In this paper, the study will be focused on the reliability and safety of the components of the lithium-ion battery, by proposing a fixable model for the evaluation of their reliability and safety. The model proposed (Triangular Intuitionistic Fuzzy Aggregating and Ranking Function (TIFARF) model), is one that has been coined from the reliability-centered maintenance concept, which is aimed at probing into the reliability and safety of the components of the battery. It is proactive reliability and safety management approach and it is intended to determine what could happen when it is used in electric vehicles or aircraft. The results from the evaluation show that the electrolyte (ES3), has the least reliability and the highest safety concerns according to the analysis and opinion represented by the invited experts. Hence the electrolyte (ES3), should be given the most or top reliability and safety priority. The model has the advantage of been able to model imprecise information in the evaluation of the reliability and safety concerns associated with the lithium-ion battery.
