Patterned Nanostructures on Cathodes: A Pathway to Stronger, High-Energy, High-Power Li-Ion Batteries.

ABSTRACT: Conventional cathodes are produced by layering materials on flat, two-dimensional substrates, imposing a trade-off between capacity retention, energy and power output, and mechanical stability. Herein, we employ programmable spray-deposition manufacturing to introduce flexibility through enabling form factors and tailored morphological nanostructures to overcome this limitation. This tailorability is achieved by creating distinct patterns─disk and ring formations─on the electrode using spray-deposition. The pattern formation is controlled by the self-assembly of lithium iron phosphate (LFP) and reduced graphene oxide (rGO), mixed at tailored mass ratios, and deposited using an in-house spray system onto an aluminum current collector. We show that when active materials are assembled into re
