Nano- and micromechanical characterization of lithium-ion battery electrodes: Adhesion & hardness

Nano- and micromechanical characterization of lithium-ion battery electrodes: Adhesion & hardness

Is adhesion of lithium-ion battery electrode a crucial issue for you? Do you want to know more about the adhesion of electrode coatings in lithium-ion batteries? Do you want to quickly measure the effects of the deposition process on the electrode coating properties? Then join our webinar on adhesion and elastic modulus measurement of electrode coatings. We will show you how to determine adhesion of functional coatings and their hardness by scratch and nanoindentation testing.

During the production and packaging of lithium-ion batteries (LIB) their components are subject to mechanical and thermo-mechanical loading. The mechanical damage to the LIB cell can lead to short circuits which increases the risk of thermal runaway or decrease of the battery capacity and lifetime. Among critical properties of the LIB electrodes are adhesion and elastic modulus. In this webinar we will present an application of the scratch test method using a wedge blade indenter for determination of adhesion of the electrode active layer. We will also show how the elastic modulus, measured by nanoindentation, is related to the formulation of the active electrode layer and how mechanical properties can serve to determine a more efficient electrode production process. This webinar is dedicated to all researchers in Li-ion electrode development and mainly those concerned with mechanical characterization.
