6 FAQs about [Battery module production issues]
What challenges does battery production face?
The rise in battery production faces challenges from manufacturing complexity and sensitivity, causing safety and reliability issues. This Perspective discusses the challenges and opportunities for high-quality battery production at scale.
What causes a battery to fail?
Beck et al. 80 reviewed the primary drivers of nonconformance in batteries and battery production. Lack of conformance to the design may not directly cause battery failure; for instance, a key quality indicator such as the distribution of cell energy may be larger than desired but still fall within an acceptable band.
Is battery quality a determinant of battery failure?
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.
Are battery quality issues affecting the reliability of battery-powered devices?
Aside from headline-grabbing safety events, battery quality issues can have outsize impacts on the reliability of battery-powered devices (Fig. 1b). For instance, an EV pack typically consists of hundreds or thousands of cells arranged in series and in parallel, often combined into modules.
What causes battery performance degradation?
Generally, the root causes of performance degradation are electrochemical and chemical degradation modes (subsequently referred to as “electrochemical” for simplicity) and have been the focus of much of the literature on battery lifetime 29, 30, 31, 32, 33, 34.
What is an example of a battery quality issue?
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.
