There is relentless research in the battery industry which aims at developing the future energy storage systems, a task which continues to be one of the crucial technological challenges. For this purpose, a series of analyses and the characterisation of product reaction effect on electrodes that take place especially at their surface and interface regions are essential. This requires analytical techniques capable of differentiating chemical states with high sensitivity and high spatial resolution.
This has led to extensive investigations on Li-ion batteries as these are envisaged as the basis for high power density secondary sources for electric vehicles and storage devices for the smart grid. Vital performance of Li-ion batteries such as cycle life, internal resistance and capacity, are closely related to the microstructure of electrodes. Solid electrolyte interphase (SEI) has proven to be crucial in increasing the performance and life of lithium-ion batteries. It is, therefore, necessary to fully understand the mechanisms and reactions which lead to the formation of SEI layers on the electrodes in Li-ion batteries.
To this end, TESCAN offers a unique
time-of-flight secondary ion mass spectrometer (
) integration which allows technologists and scientists working in the battery industry to perform high resolution surface analyses such as depth profiling and elemental distribution maps to shed light on SEI in Li-ion batteries.
Additionally, LYRA3 or FERA3 can be used to implement
to reconstruct the evolution of the 3D structure of Li-ion battery electrodes during extended cycling.

Lithium ion batteries are a leading energy storage technology for electronic portable devices and hybrid electric vehicles. Simultaneous characterization of the structure, chemical composition and elemental distribution in Li-ion battery materials can reveal the relationship between Li-ion transport, structural effects (phase transformation, internal stress), and battery performance and its degradation.
