Abstract 

At Oregon State University, we seek a fundamental understanding of design principles for electrodes for new, sustainable batteries. We take an iterative approach to gain knowledge by integrating rational syntheses, advanced characterization (including synchrotron x-ray, neutron scattering, and associated pair distribution function studies), and DFT calculations. I will talk about our recent results on the mechanisms of Na-ion and K-ion storage in nongraphitic carbon. I will introduce a design principle of a hard carbon anode for Na-ion batteries based on its structure-property correlations. I will discuss the limitations of carbon anode materials for K-ion storage and strategies for addressing them. I will also discuss the relevance of organic solids as cathodes for dual-ion batteries. Additionally, I will share new results on the emerging hydronium-ion and ammonium-ion batteries.
