AI Customer ServiceQuality control in battery cell manufacturing requires in- line product measurement as well as offline laboratory analysis for a characterization of crucial electrode
AI Customer ServiceElectrochemical tests, which included capacity and impedance measurements, found that both types of batteries met the specifications. However, computed tomography (CT) scan, disassembly, and material characterization revealed quality concerns in battery assembly and material composition.
A tool for quality-oriented production planning in assembly of battery modules was developed by , defining critical product and process characteristics and deriving appropriate quality assurance systems using a measurement equipment catalogue.
This paper addresses this challenge by including battery quality evaluation of assembly precision and material composition beyond electrochemical verification. The results of the quality testing showed that the Type A battery has a stacked electrode configuration, and type B has a jelly-roll arrangement.
For the battery manufacturers, the quality control covers steps from the raw material collection to the fabrication of components, including the electrode, separator, electrolyte, current collector, and the battery case/can and lid or pouch.
Consequently, re-evaluating the impact of purity becomes imperative for affordable lithium-ion batteries. In this study, we unveil that a 1% Mg impurity in the lithium precursor proves beneficial for both the lithium production process and the electrochemical performance of resulting cathodes.
Discrepancies existed for the cathode material. For cell B, the NMC material specified by the battery manufacturer turned out to be LCO. From this analysis it can be concluded that lithium-ion battery quality evaluation should incorporate electrochemical performance tests and assessments of assembly precision and material composition.
We are deeply committed to excellence in all our endeavors.
Since we maintain control over our products, our customers can be assured of nothing but the best quality at all times.
