Summary: By studying the microstructure of hard carbon materials, it is found that sodium storage capacities in the low potential plateau region involve contributions from both interlayer intercalation and micropores filling, with the ratio depending on the microstructure. The dominance of interlayer intercalation and micropores filling processes in the low potential plateau region can be distinguished by the potential inflection point at the end of the discharge curve. A microstructure-dependent mechanism is proposed to explain the sodium storage behaviors in different hard carbon materials.

Summary: In this study, a modified co-precipitation method was used to synthesize highly crystallized Prussian Blue analogs (PBAs). By introducing zinc as an electrochemical inert element to substitute high-spin iron, a highly reversible phase transition process for sustainable sodium-ion storage was achieved, resulting in improved cycle stability and specific capacity. In-situ tests confirmed minor lattice distortion and highly reversible phase transition of the zinc-substituted PBA during sodium-ion insertion and extraction, which greatly influenced the cycling stability. The zinc-substituted PBA exhibited remarkably enhanced cycling performance with a capacity retention of 58.5% over 2000 cycles at 150 mA g(-1) and superior rate performance up to 6000 mA g(-1).
