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.

Particle Analysis of Film and Battery
The XGT-9000 can detect and determine the composition of foreign particles, and therefore track the source of contamination.
Laser Diffraction Analysis of Lithium Ion Battery Material
Battery technology is improving, keeping up with the demand for better power storage. Improved performance requires greater control of the materials used and their physical properties including the particle size distribution.
Microscopic Measurement of Diffusion
Spectra taken at different depths within the polymer layer with normalized spectra.
In order to engineer materials with controlled diffusive properties, we need to be able to measure the diffusive process in situ. Ideally, we would like a technique that provides molecular information with resolution on a microscopic scale, that is non destructive of the samples, and can be set up and used on a laboratory bench top with a minimum of time and effort involved in sample preparation. Raman microprobe spectroscopy is an ideal candidate for this type of studies. Use of visible light combined with a confocal microscope provides a probe with spatial resolution of a micron or better, and coupling of such a microscope to a modern Raman spectrometer equipped with holographic notch filters and CCD multi channel detectors allows rapid acquisition of Raman spectra which can be correlated with the chemical state of the species and its physical environment.
Features and Benefits of Pulsed RF GD OES for the Characterisation of Electrodes of Li-ion Batteries.
A Li-ion battery.
A Li-ion battery is a rechargeable battery in which lithium ions move between the anode and the cathode creating an electricity flow. Whether you study new electrodes or coatings behaviors, charge and discharge processes, process controls, or perform comparative studies for Li-ion batteries, Pulsed RF Glow Discharge Optical Emission Spectrometry is a valuable companion tool.
Raman Spectroscopy Applied to the Lithium-ion Battery Analysis
Raman image LiCoO2 cathode after a cycling process.
The application note explains how the Raman Spectroscopy can be helpful in the analysis of cathodes and anodes in Li-ion batteries. Today’s state of art of technology requires more reliable, more efficient and powerful energy sources. Lithium-ion batteries are thus of high interest. Raman spectroscopy adapts to the different stages of life of these batteries, such as the characterization of new materials for more flexible systems, failure analysis; but also more standard analysis of used material during charge/discharge process, including structural and electronic properties, and even robust, automated QC tests.
