6 FAQs about [Current battery quality]
How important is battery quality?
Battery quality also has important impacts on questions around battery reuse and recycling 122. While energy retention is an important metric to determine suitability for reuse, the presence of cell failure and defects arguably should be the primary gating item for this decision.
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 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.
Why is battery performance important?
Fundamentally, the challenge of ensuring battery quality is driven by the complexity of battery performance. An especially important, sensitive, and complex pillar of battery performance is battery lifetime and failure.
Are counterfeit batteries safe?
Counterfeit cells of course often have very poor quality, and many of the highly-publicized battery safety events discussed previously are a result of low-quality and/or counterfeit batteries 10, 13, 71. We now consider a second definition of battery quality: conformance.
