BIPHASIC ELECTRODE SUSPENSION FOR A SEMI-SOLID FLOW CELL

摘要

A biphasic electrode suspension for a semi-solid flow cell comprises a polar solvent, a nonionic dispersant, a first plurality of particles having repulsive interactions and comprising an electrochemically active material, and a second plurality of particles having attractive interactions and comprising an electronically conductive material. The nonionic dispersant is present in an amount sufficient to sterically stabilize the first plurality of particles, but insufficient to sterically stabilize the second plurality of particles. The second plurality of particles forms a percolating conductive network through the first plurality of particles.
