💡 Novelty & Significance:
This work introduces low-melting-point metal salt precursors for O3-type layered oxide cathodes, enabling synchronous decomposition that suppresses residual stress accumulation. Compared to conventional oxide routes, this strategy lowers activation energy, ensures uniform lattice strain, and prevents particle cracking during cycling. It establishes stress regulation as a key design principle for high-stability sodium-ion battery cathodes.
