"Spicy world of NanoScience" since 2007
Development of advanced lithium batteries currently represents a very rapidly growing field of science and technology. Lithium batteries are interesting as a power source in numerous portable devices, in electrical vehicles, in military and aerospace applications. What factors determine the cycle life, self-discharge rate, energy density? Optimization needs the complimentary usage of different analytical approaches.
In the attached application note different Li-ion battery cathodes are analyzed by simultaneous AFM and confocal Raman imaging. Comprehensive information about lithium intercalation processes and cathode degradation is obtained on a submicron scale.
