Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
A full cell using Si@Cu3(HITP)2-5 anode and LiCoO2 cathode demonstrates practical LIB applicability, including retained 1038 mAh g-1 after 50 cycles and 1105 mAh g-1 at 1C.
Caveat: Full-cell capacity retention is modest at 45.8%, and authors attribute fading partly to cyclable lithium loss and anode/cathode imbalance.
13 · Results and discussion · Fig. 9 · Linked to 3 structured results
Increasing Cu-MOF content lowers initial coulombic efficiency and can reduce capacity because higher surface area and N/O/H-containing groups promote side reactions and reduce the absolute Si fraction.
Caveat: Mechanism is inferred by authors from surface area/composition trends and electrochemical behaviour.

The Cu3(HITP)2 coating buffers Si volume expansion, reduces pulverisation and preserves electrode integrity during cycling.
Caveat: Expansion comparison is based on electrode thickness and microscopy after cycling, not in situ dilatometry.
12 · Results and discussion · Fig. 8 · Linked to 3 structured results
The 5 wt% nominal Cu-MOF loading gives the best balance of buffering/conductivity and active Si content for half-cell capacity retention.
Caveat: Higher Cu-MOF loadings can outperform at some ultrahigh C-rate points but have lower long-cycle capacity.
9 · Results and discussion · Fig. 6 · Linked to 4 structured results
A 3 wt% Cu-MOF coating improved pure-Si cycling somewhat but was insufficient to control SiNP volume expansion and degradation compared with the 5 wt% target.
Caveat: Derived from SI Fig. S8 low-loading comparison; 50-cycle Si@Cu3(HITP)2-5 capacity in that SI comparison is lower than the 100-cycle main-text value because it is a separate plotted comparison.
S10 · Fig. S8 text · Fig. S8 · Linked to 3 structured results
In-situ growth of Cu3(HITP)2 on SiNPs creates a more intimate Cu-MOF/Si contact than prior mechanical mixing approaches.
Caveat: Direct comparative data against mechanically mixed Cu3(HITP)2/Si are not shown in this paper.
2 · Introduction · Linked to 3 structured results
Cu3(HITP)2 is treated as a conductive porous 2D Cu-MOF that can provide electron- and ion-conducting channels around Si nanoparticles.
Caveat: First-hand conductivity was measured on a Cu-MOF/LiPAA-binder mixture, not a binder-free pellet.
