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.
Is battery quality a barrier to accelerating battery production?
These three challenges have a common theme: battery quality. Among the various obstacles facing the battery industry, ensuring high battery quality may be the greatest barrier to accelerating battery production in the years to come. In this article, we’ll first define battery quality and related concepts such as battery failure and reliability.
What does poor battery quality mean?
Under this definition, poor quality means that the as-built cells deviate substantially from their design. This definition of battery quality is more general since it can include dimensional specifications and electrochemical properties as well as the lack of physical defects. Poor conformance has a number of impacts on the final product.
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.
Is battery quality control a problem?
Battery quality control in the real world We’ve established that battery quality is a problem. As in all manufacturing processes, the solution is battery quality control. While battery quality control is a multifaceted problem worthy of its own article, a key element is inspection.
Why is battery quality important?
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.
