The safety and reliability of Li battery are determined mainly by its basic design and chemistry. However, without adequate quality control during manufacture, defects in even the best designs can lead to inconsistent performance and early failure. Deployment of automated quality assurance technology at every stage of the manufacturing and assembly process will increase the reliability and safety of batteries while lowering overall manufacturing costs by reducing wastage and preventing defective components from being incorporated into the finished product During presentation the particular attention will be paid to various non-destructive & non-contact methods and equipment based on the following methods: Electromagnetic eddy-current,Electromagnetic capacitance,Combined electromagnetic eddy-current & capacitance;Holographic Interferometry;Gas Discharge Visualization – High Voltage Electric Field methodUltrasonic with dry contact The goals are to conducting the non-destructive non-contact testing & evaluation the following properties of initial materials, semi and final production including in-line control during batteries production (is not limited to): Conductivity, composition and purity of the powder materials, liquids, polymer & slurry compositions;Interface resistance between current collector and active electrode massThickness measurement & quality assurance during the electrode coating.Hidden defect in electrodes, solid electrolytes and other components.Hidden defects in multiple layer structure, for examples, Jelly Roll in battery & ultracapacitorWeld quality hidden faults in batteries and ultracapacitors Major advantages of the Enerize non-destructive non-contact testing methods are as following: Reliability due to non-contact mode of operation.Efficient, fast, simple, and inexpensive to implement.Easy to automate. Results are obtained in real-time.Do not require any special protection for operators and equipment. Safe and less expensive than X-ray methods.Precise determination of specific parameters and defects.Provide 100% nondestructive control of the technological operations and the quality of the end product.Provide quality control of material and products for which contact methods, in principle, cannot provide reliable information due to extraneous processes at the sensor/test article interface surface.Provide quality control of new materials, including nanomaterials and thin-layered materials, which can be sensitive to mechanical contact. Non-destructive methods and equipment that developed by Enerize could be used non only during Li batteries production but also during production of the supercapacitors, solar cells, fuel cells, and in chemical, pharmacy, petro chemistry, and construction industry References.
