In this webinar we introduce full Survey Chemical Analysis of Materials Used in Energy Storage Devices such as lithium ion batteries.
In energy storage devices such as lithium ion batteries (LIB), manufacturing uncertainties arise not only from fluctuation of processing parameters, but also from the quality of precursors and formulated intermediate products. Defects introduced by unwanted or unintentional impurities and composition off-stoichiometry, inevitable as the consequence of thermodynamics, are important sources of uncertainties. Like all dynamic systems, the interplay between structure defects and cell performance is strongly coupled. Off-stoichiometry-related crystal defects can destabilize the layered structure of cathode, thus shortening the cycle life, while impurity defects are known to participate in multiple chemical, physical and electrochemical processes that either accelerate aging or directly lead to failure of batteries:
