شناسايي و اولويت بندي عوامل موثر بر بالا بردن كيفيت باتري هاي ليتيوم-يون با استفاده از روش تركيبي دلفي فازي، AHP فازي و ويكور فازي

Increasing deman‎d for clean an‎d efficient energy resources has made the development an‎d quality improvement of lithium-ion batteries increasingly essential. Owing to their high energy density, suitable lifespan, an‎d wide range of applications in sectors such as automotive industries, electronic devices, an‎d energy storage systems, these batteries have gained a vital position in current research. Nevertheless, the performance an‎d quality of lithium-ion batteries are influenced by a set of technical, economic, an‎d environmental factors. Therefore, identifying an‎d prioritizing these factors in order to improve the design an‎d manufacturing processes is considered necessary. Based on previous studies, the absence of a comprehensive multi-criteria decision-making system for eva‎luating an‎d ranking these factors is clearly observed. To address this issue, the present study first extracted the most important factors an‎d indicators affecting the quality of lithium-ion batteries through an extensive literature review. Subsequently, these factors were eva‎luated using the opinions of 15 industry experts an‎d specialists in the lithium-ion battery field from different sectors, including Saba Battery Company (6 experts), Sepahan Battery Company (2 managers an‎d 4 experts), an‎d defense industries (3 experts). To manage uncertainty an‎d enhance decision-making accuracy, fuzzy approaches an‎d multi-criteria decision-making methods—namely Fuzzy Delphi, Fuzzy Analytic Hierarchy Process (FAHP), an‎d Fuzzy VIKOR—were employed. In the first step, key criteria were identified an‎d categorized into three dimensions: technical, economic, an‎d environmental. Then, Fuzzy Delphi was applied to achieve expert consensus regarding the selec‎tion of these criteria. Next, FAHP was used to calculate the weights of the criteria, an‎d finally, the ranking of the factors was carried out using the Fuzzy VIKOR method. The results indicate that among all examined factors, precise parameters in the electrode coating process an‎d separator quality have the most significant an‎d decisive impact on the quality of lithium-ion batteries, whereas some economic an‎d environmental factors were ranked with lower priority. The findings of this research can serve as a scientific an‎d practical framework for managers an‎d engineers in related industries to support more informed decision-making an‎d enhance product quality
