NMR: A Powerful Tool for Optimizing Battery Performance

Nuclear Magnetic Resonance (NMR) is a widely used analytical technique in chemistry and materials science that provides a deeper understanding of battery material properties and behavior. In battery research, NMR investigates the atomic and molecular structures of battery materials, allowing researchers to identify chemical and physical changes occurring during charge and discharge cycles. To effectively measure these processes and critical quality attributes, analytical solutions for the characterization of batteries should be able to operate in situ. NMR spectroscopy offers an ideal analytical method to address the need for accurate, responsive, in situ detection in the battery sector. It assists in identifying reasons for battery degradation and failure, enabling the development of new, more durable, and stable electrode materials. By providing a detailed analysis of the chemical and physical properties of battery materials, NMR helps optimize battery performance and efficiency.
