UNRAVELLING THE INTRICACIES OF LITHIUM-ION BATTERY AND ITS DEGRADATION DYNAMICS

Subject Area: Engineering

In order to solve degradation-related difficulties, a thorough knowledge of lithium-ion battery (LIB) behaviour is important given the rapid expansion of EVs and mobile devices. With LIBs driving EVs and influencing the direction of energy storage, the globe is embracing renewable energy. This study unravels the complex dynamics that affect LIB performance by exploring important topics including temperature affects, charging methodologies, and rapid charging. As a solution to longer charging periods, fast charging reveals trade-offs, such as increased deterioration and safety issues. Temperature turns out to be a critical component that affects lithium plating, ion diffusivity, and battery health in general. Sustainable LIB usage hinges on an efficient charging approach that takes health-related factors into account and minimizes temperature extremes, overcharging, and over discharging. An essential statistic that provides information on the degree of deterioration and its ripple effects on power, voltage, capacity, and internal resistance is the state of health (SOH). This research uses a mathematical model that incorporates internal resistance and coulomb efficiency to capture the core of LIB behaviour during charging and discharging. The suggested approaches which include lower charging current, better charging, and thermal management show the way to longer battery life spans. Careful monitoring and management are essential when it comes to issues like charging inconsistencies, temperature extremes, and charge cycles. Essentially, this study explores the challenging landscape of lithium-ion batteries (LIBs), highlighting their weaknesses and suggesting ways to achieve high-performance, sustainable energy storage. The path to realizing the full potential of lithium-ion batteries requires ongoing research, creative thinking, and a dedication to reshaping the energy landscape to be more efficient and environmentally friendly.
