Abstract
En 中文
• Zr doping of NMC811 via co-precipitation step explores solubility limits. • Synchrotron XRD/ XAS confirms the successful Zr incorporation into NMC811 structure. • Zr content above 0.1 mol% leads to form an additional Li2ZrO3 polymorphs phases. • Higher Zr concentration yields a smaller particle size distribution. • Morphology changes have a higher influence than doping on electrode cyclability.
