Structure-Property Relationships in Porous Electrodes for Electrochemical Energy Storage

The objective of this proposal is to fill this gap in knowledge by quantifying the microstructure of porous battery electrodes and developing relationships linking this structure to ionic and electronic transport within it. We will pursue this objective using advanced neutron scattering techniques that will characterize in unprecedented detail microstructural features that determine the balance of electrical and ionic transport in battery electrodes. To achieve this objective, this proposal consists of two thrusts:1.) Quantifying binder-carbon interactions using small-angle neutron scattering (SANS)2.) Understanding microporosity and electrical percolation
