AI Article Synopsis
- Developed a new O3-structured Na(LiNiSiTiCuMg)O-based cathode for Na-ion batteries to improve efficiency.
- Substituted Si for Ti in the metal layer, which altered the properties of the Na-O bond and made it weaker and longer.
- Increased 'inter-slab' spacing boosts the movement of sodium ions, improving transport kinetics for better battery performance.
Article Abstract
By developing a high-rate-capable O3-structured Na(LiNiSiTiCuMg)O-based cathode material for Na-ion batteries, wherein partial substitution of more electronegative Si for Ti in the transition metal layer has weakened-cum-lengthened the Na-O bond, enlarged the 'inter-slab' spacing and, thus, enhanced the Na-transport kinetics, a design criterion has been laid-out in the above context.
