Battery Screening

Battery cell screening and selection guarantee a longer service life of your battery driven products


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 undisputed scientific proof

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 mechanism in screened lithium-ion battery cell and provides indisputable screening and selection for guaranteed service life.

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.

The Examight System: Redefine your battery screening and selection

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

The ExaMight software and workflow need no changes in the customer process and require minimal work force qualification.
