Abstract
The rapid expansion of electric vehicles (EVs) necessitates a deeper understanding of EV battery lifespan dynamics, presenting significant challenges and opportunities. This study focuses on key understanding in EV battery lifecycle management, emphasizing comprehensive recycling methods to ensure sustainable integration of EVs into the transportation sector. By examining EV battery performance metrics and technical approaches to enhance recyclability, the study provides a thorough analysis of environmental and economic impacts. Using MATLAB for numerical analysis, this research is expected to take an integrated approach to solving the issues of EV battery management, providing significant insights and techniques for full EV battery recycling. The analysis highlights the growth of EV battery market could increase from 1066 GWh in 2024 to 120000 GWh in 2050 in an optimistic scenario. The study also shows that the current mainstream lithium ion batteries in EVs shows faster degradation of state of charge which is at 73.33% of remaining capacity compare to solid state batteries which are still new to the EV industry with the remaining capacity of 86.67% after 2000 cycles of charge-discharge. Beside, for 100 kWh , the lithium ion battery weights at 377.36 kg while solid state battery only weights 200 kg. We propose various suggestion involving partnerships with global battery manufacturers, expansion of charging infrastructure, promotion of solid-state batteries, and implementation of financial incentives to support EV adoption. The adoption of EVs and their performance is correlated to the recyclability potential of EV battery.
