Life-Cycle Optimization and Flow Control in a Nickel-Zinc Flow Assisted Battery
… has been hindered by the well-known phenomena of dendrite formation and zinc morphology variation over time. Applying electrolyte flow to traditional nickel-zinc battery systems has demonstrated significant life cycle performance improvements by reducing both dendrite formation and morphological …

Understanding surface reactivity, local structure, and lithium-metal dendrite initiation in garnet solid electrolytes
… local structure of dopants in doped LLZO and the dendrite formation have not been systematically characterized and understood. This thesis elucidates the importance of the gas atmosphere and temperature for regeneration by tracking the surface of LLZO with near ambient pressure x-ray photoelectron …
