These should have more energy and performance, and be manufactured on a sustainable material basis. They should also be safer and more cost-effective and should already consider end-of-life aspects and recycling in the design. Therefore, it is necessary to accelerate the further development of new and improved battery chemistries and cells.
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.
Cost-effective characterization techniques for battery quality may enable more cells to be reused in a second-life application instead of immediately recycled 78. While regulatory efforts around battery safety are only just beginning 13, we expect more will arise as more battery safety incidents occur.
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.
On the other hand, it is possible to reduce the production cost of batteries by giving some tax incentives to battery manufacturers or manufacturers of core components of the battery industry based on overall considerations of their production quality, sales performance, innovation ability, customer satisfaction, and other aspects.
In this way, battery manufacturers can use safer and better-performing new raw materials to produce batteries. It will enable battery manufacturers to use safer and better-performing new raw materials to make batteries. Thus, it will enhance the performance of NEVs and ultimately benefit consumers.
