Global efforts by researchers and engineers in battery modeling and testing have led to the development of powerful tools for investigating battery behavior under abuse conditions [28, 29]. However, our ability to predict the risk of hazardous battery failure under realistic conditions remains limited .
Future perspectives are provided, covering materials, cells, and system levels. Battery failures, although rare, can significantly impact applications such as electric vehicles. Minor faults at cell level might lead to catastrophic failures and thermal runaway over time, underscoring the importance of early detection and real-time diagnosis.
Recognizing the complex interplay of physical and chemical factors in battery failures is vital. An integrated approach, blending hardware and software solutions, is essential for advancing battery safety and ensuring a secure, sustainable future in diverse applications. 6.1. Comprehensive approaches to unravel battery failure mechanisms
This Insight provides clarity into the current state of knowledge on LIB degradation1 and identifies where further research might have the most significant impact. Battery degradation is a collection of events that leads to loss of performance over time, impairing the ability of the battery to store charge and deliver power.
Understanding the various levels of battery safety hazards (Table 1), is essential for effective battery management and diagnostics. Table 1. Characteristics of battery safety hazards (fault, failure, and thermal runaway). Minor reduction in efficiency. Noticeable reduction in battery life and performance.
Central to this approach are comprehensive monitoring, early diagnosis, and risk prediction at the cell, pack, and system levels, which address the challenges and enhance the safety of batteries in practical applications.
