Judging the quality of energy storage batteries

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.

How important is quality control in battery production?

Generally speaking, a strong emphasis on quality and quality control can be a powerful lever to minimize wasted material and energy during battery production. Given the frequency, severity, and inevitability of battery quality issues, both battery producers and manufacturers of battery-containing products must manage battery quality.

How sustainable is battery production?

Finally, we mention that the sustainability of battery production is becoming an increasingly important manufacturing performance metric. For instance, an estimated 30–65 kWh are consumed in the factory for every kWh of cells produced 45, 87.

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.

Why is accurate battery status estimation important?

Accurate battery status estimation is of utmost importance to effectively estimate both battery charge and health.

Can characterization techniques improve battery quality?

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.
