Battery Screening


Your Challenge: Poorly produced cells

Minor changes in the production process of your battery supplier lead to major changes regarding battery performance and service life of your product. The key for long-lasting battery systems is to screen incoming batteries and select optimal cells for your application.

The solution: Identifying strong cells

The performance and service life time of your battery system is determined by the worst battery cell. That is why the integration of batteries with quality issues jeopardize your product’s success.

How we do it: The Safion method

The sole measurement of the internal resistance (IR) and open circuit voltage (OCV) as inspection techniques can not identify lithium-ion battery cells of reduced service life. Only the measurement of at least 20 impedance points at different frequencies reveals hidden degradation mechanisms in screened lithium-ion battery cells. Safion's method provides precise insights for cell selection and a guaranteed service life.

Safion’s battery screening system ExaMight reduced the measurement time for the impedance spectrum of more than 20 points from minutes to seconds. This enables an extremely high screening throughput.

It works: The undisputed scientific proof

Numerous scientific publications back the capabilities of Safion’s online electrochemical impedance spectroscopy (oEIS) technology and prove the strong evidence between the screening results and battery service life.
