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.
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.
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.
Battery quality is among the most difficult issues facing the industry today due to the complexity of both battery failure and gigawatt-hour-scale battery production. Yet the human, environmental, financial, and reputational stakes are enormous. The challenge of battery quality deserves much more academic, industrial, and regulatory focus.
The complexity of the battery manufacturing process, the lack of knowledge of the dependencies of product quality on process parameters and the lack of standards in quality assurance often lead to production over-engineering, high scrap rates and costly test series during industrialization .
