    Electrode Damage Characterization in Li-Ion Batteries Using Raman Spectroscopy

    While Li-Ion battery technology has continually advanced to provide cells that are smaller and more powerful, compromised safety concerns due to physical damage are always present. Physical damage to a Li-Ion battery can significantly affect its operational performance, causing accelerated degradation and capacity fade. Damage to electrodes and removal of active material lead to microstructural changes in electrode material and unbalanced current distribution, causing polarization in cells. This work focuses on characterizing the effects of partial nail penetrations on electrodes in cells that continue cycling after being damaged by using Raman spectroscopy and incremental capacity analysis. This helps to determine the type and extent of damage to the electrodes over the course of their abbreviated lifetime.

    This webinar will focus on the following key topics:

    • Dynamic impact testing of prismatic Li-Ion cells
    • Raman spectroscopy analysis for anode damage characterization
    • Increased polarization due to unbalanced current distribution
    • Accelerated degradation caused by physical damage
    • Incremental capacity analysis to determine mechanisms of aging

    XRF Analysis in Process Control of Battery Cathode Manufacturing

    To optimize the chemical composition of the final cathode materials, it is first essential to control the chemical composition of the precursor and raw materials. X-ray fluorescence (XRF) analysis, which can characterize chemical composition and impurities from just a few ppm all the way up to 100%, is the best technique for controlling this parameter.

    Specifically, XRF provides a simpler and more accurate way of measuring elemental composition than inductively coupled plasma (ICP) mass spectrometry, as it does not require any sample dilution or acid digestion.

    Malvern Panalytical specialists have developed a turn-key solution, including certified reference materials (CRMs) and calibration templates, for the analysis of both precursor and cathode material composition with the benchtop Epsilon 4 EDXRF or floor-standing Zetium WDXRF spectrometers.

    This webinar will focus on the following key topics:

    • On-line and at-line XRF analysis of solutions containing Ni, Co and Mn
    • NCM-certified reference materials for XRF calibration purposes
    • Turn-key solution for the XRF analysis of NCM precursors and cathodes
