Acoustic emission measurements collected during electrochemical tests, combined with advanced imaging techniques such as transmission X ‐ ray microscopy, provide a window into the internal
workings of battery materials during energy storage cycles.
Beyond this, the methodology is well suited as a test procedure for a
variety of battery materials, for example the development of new admixtures that suppress lithium plating.
«Hydro - Québec has developed extensive expertise in the
area of battery materials scale - up and commercialization for electric vehicles and grid storage,» said Karim Zaghib, General Director of the Center of Excellence in Transportation, Electrification and Energy Storage and Conversion (CETEES) at Hydro - Québec.

Their fluorescence studies show that even after only a few charging cycles, damage to the inner structure
of the battery material is clearly evident, damage which takes longer to arise during slower charging.
Also, 99 %
of the battery materials can be recycled and only sodium must be handled as a hazardous material.
By reclaiming
some of the battery materials (zinc, manganese and steel, for instance), fewer virgin materials are needed, which can offset part of the environmental impact of resource extraction.
