Overview
The development plan for sodium cathodes involves a multi-faceted approach focusing
on improving energy density, cycle life, and power capability, while also addressing
structural stability and cost. Key strategies include synthesizing high-performance
materials like layered transition metal oxides and polyanionic compounds, using
advanced characterization techniques to understand reaction mechanisms, and
implementing surface modifications and dopants to optimize the electrode-electrolyte
interface.
A general strategy involves creating a synthesis phase diagram for pre-screening
and selecting a stable platform material, followed by elemental substitution to enhance
structural stability and performance.
