In summary, both senses of battery quality (defectiveness and conformance) are critical determinants of battery failure and thus the financial success of cell and EV production endeavors. We revisit battery quality in the “Managing battery quality in production” section.
Throughout this section, we use the example of electrode overhangs (subsequently referred to as simply “overhang”) as a canonical example of a battery quality issue. Insufficient overhang may cause lithium plating, which may cause an internal short and, in extreme cases, thermal runaway 52, 74, 75.
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 .
Table 1. Characteristics of battery safety hazards (fault, failure, and thermal runaway). Minor reduction in efficiency. Noticeable reduction in battery life and performance. Significant risk of failure, potential fire hazard. Substantial loss of performance and capacity Immediate and severe risk of failure, potential explosion.
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.
