PhD Overview
My PhD focuses on developing advanced energy materials using cobalt extracted from Zambian ores. I have successfully produced high-purity sodium cobalt oxide (NCO), which is used as a flux binder in cold sintering of solid-state electrolytes like Na₃Zr₂Si₂PO₁₂ (NZSP) and in enhancing superconducting properties of YBCO composites. The research explores sustainable processing methods, including microwave-assisted leaching and low-temperature sintering, aiming to reduce environmental impact while improving material performance. This work supports the global shift to clean energy and adds value to Zambia’s critical minerals through innovation in battery and superconductor technologies, contributing to circular economy and resource sustainability.
Sustainability Goals
- Affordable and Clean Energy
- Decent Work and Economic Growth
- Industry, Innovation and Infrastructure
About Me
I am a Materials Science Engineer with 19 years’ experience in Zambia’s mining sector and academia. Currently a PhD researcher at the University of Sheffield, pioneering cobalt extraction from local ores for battery and superconductor applications. I champion sustainable energy, value addition to Africa’s critical minerals, and have mentored over 100 female metallurgists.
