European Cell Manufacturer

Company

A global battery manufacturer with decades of expertise, delivering advanced lithium-ion cells into mission-critical applications such as aerospace, defense, and transportation. In these markets, safety and reliability are non-negotiable, and quality assurance processes are held to the highest possible standards.

Challenge

To meet these requirements, the manufacturer relied on extensive aging protocols that stretched testing cycles up to a full month before cells could be released. While this approach provided confidence in performance, it created significant bottlenecks: production space was tied up for weeks, feedback loops for process optimization were painfully slow, and scaling new lines became inefficient and costly. The core challenge is clear — how to maintain uncompromising quality while shortening the time-to-feedback in cell manufacturing.

Limatica Approach

Limatica is collaborating with the manufacturer to implement its noise-based diagnostic technology as an alternative to month-long self-discharge measurements. By analyzing voltage noise, which reveals intrinsic activity inside the cell, meaningful diagnostic results can be obtained in around 30 minutes. Unlike traditional methods, the approach is independent of relaxation effects, ensuring reliable outcomes across different chemistries and formats. Together, we are validating the method to prove that even the strictest safety and reliability requirements can be met without lengthy aging.
