Optimizing Formation Processes in Lithium-Ion Battery Manufacturing: Enhancing Efficiency and Quality for Electric Vehicle Applications

Aim: To examine the optimization of the formation processes in lithium-ion battery manufacturing in order to enhance its efficiency and quality for electric vehicle applications. Problem Statement: The global concern regarding increase in greenhouse gas emissions which has been a major factor in the climate change has greatly influenced the prevailing of electric vehicles as a sustainable transportation means. Significance of Study: This technical review is an eye-opener for researchers on the need to optimize the formation process of Lithium-ion batteries (LIBs) which are being utilized in electric vehicles. Methodology: Recent literature materials in form of books, journals and relevant published articles in the area of formation processes in lithium-ion battery manufacturing were consulted. Discussion: In this technical review, consideration is given to the optimization of formation processes in lithium-ion battery manufacturing as a means to improve its efficiency and quality for wide applications in electric vehicle. The sequential steps required for Li-ion battery production are divided into three main stages which are electrode manufacturing, cell assembly and cell finishing. Additionally, the essential steps involved in the formation process are explained. However, the formation process is identified to usually be a production bottleneck due to the relatively low currents used in individual cells. The major influencing factors affecting the Li-ion battery formation process are formation cycling, temperature and pressure. Conclusion: There is need for Li-ion battery manufacturers to optimize these parameters and consider them during the formation processes to boast the quality and efficiency of the Li-ion battery in electric vehicles.
