| contents | As the impacts of climate change become increasingly apparent, the need for widespread electrification is now internationally recognized. As a result, global battery production is set to dramatically expand over the next decade. Unfortunately, however, batteries are both immensely difficult to produce at the gigawatt-hour scale and inordinately sensitive to minor manufacturing variation. As a result, the battery industry has already experienced a number of both highly-visible safety incidents and under-the-radar reliability issues -- a trend that will only worsen if left unaddressed. In this perspective, we highlight both the challenges and opportunities to enable battery quality at scale. We first describe the interplay between various battery failure modes and their numerous root causes. We then discuss the tensions at play to manage and improve battery quality during cell production. We hope our perspective brings greater visibility to the battery quality challenge to enable safe global electrification. |
