Characterisation of battery materials by electron and ion microscopy techniques: a review
Abstract
Development of highly efficient batteries with more rational understanding and precise control of the underlying microstructural features requires high resolution based characterization tools. Electron microscopy and spectroscopy offers information about the structure, morphology, chemistry and chemical composition of the battery materials on nano and atomic scale enabling us to establish the synthesis-structure-performance relationship and further direct the design of new battery materials with improved and high performance.
The key factors for a successful electrochemical system are the structure, morphology, chemistry and chemical information of the component materials. The improvement and further development of energy storage systems is based on detailed knowledge and interpretation of morphology, microstructure and phase composition of the individual components like electrodes, current collector, and separator. Additionally, the long-term stability of batteries is affected by the interaction of several components not only at their common interface but also in the volume of the whole device and in combination with intrinsic emerging mechanical loads. Battery materials require advanced skills and techniques to improve material combinations and synthesis strategies. High quality images, in situ measurements and chemical analysis can contribute to this.- Publication:
