Battery

The battery market has grown dramatically since the first commercial introduction of automotive applications in the early 90’s, as well as increased demands for other electronic devices. Difficult issues, such as increasing capacity needs, safety, and longevity as well as the demands for weight reduction and charge times all need to be addressed.  Every stage of the manufacturing process needs to be understood and controlled in order to maintain competitiveness and profitability. From any single component (cathode, anode, separator and electrolyte) to full pack, the scientific fields and technologies involved require fast and innovative characterization tools.

Advanced materials research considers study of new material as well as their exploration at material level. Applied research will conciliate needs of industrialization through optimization of cell chemistry, establishment of advanced processing technologies and life time improvement. Advanced batteries development finalizes the performance optimization and cost reduction. Batteries production requires fast, easy and accurate QC monitoring, which provides fast detection of defaults in safety and performances issues, along with fast decision making when default is suspected. This will save time and money, while providing perfect traceability.
