Bioinspired design of Na-ion conduction channels in covalent organic frameworks for quasi-solid-state sodium batteries

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: May 27, 2023

Solid polymer electrolytes are considered among the most promising candidates for developing practical solid-state sodium batteries. However, moderate ionic conductivity and narrow electrochemical windows hinder their further application. Herein, inspired by Na+/K+ conduction in biological membranes, we report a (-COO-)-modified covalent organic framework (COF) as Na-ion quasi-solid-state electrolyte with sub-nanometre-sized Na+ transport zones (6.7-11.6 Å) created adjacent -COO- groups COF inwalls. The enables selective along specific areas that electronegative sub-nanometre dimensions, resulting of 1.30×10-4 S cm-1 oxidative stability up to 5.32 V (versus Na+/Na) at 25 ± 1 °C. Testing Na||Na3V2(PO4)3 coin cell configuration demonstrates fast reaction dynamics, low polarization voltages, stable cycling performance over 1000 cycles 60 mA g-1 °C 0.0048% capacity decay per cycle final discharge 83.5 mAh g-1.

Supramolecular Polymer Ion Conductor with Weakened Li Ion Solvation Enables Room Temperature All‐Solid‐State Lithium Metal Batteries

Angewandte Chemie International Edition, Journal Year: 2023, Volume and Issue: 62(35)

Published: July 6, 2023

Improved durability, enhanced interfacial stability, and room temperature applicability are desirable properties for all-solid-state lithium metal batteries (ASSLMBs), yet these desired rarely achieved simultaneously. Here, in this work, it is noticed that the huge resistance at Li metal/electrolyte interface dominantly impeded normal cycling of ASSLMBs especially around (<30 °C). Accordingly, a supramolecular polymer ion conductor (SPC) with "weak solvation" Li+ was prepared. Benefiting from halogen-bonding interaction between electron-deficient iodine atom (on 1,4-diiodotetrafluorobenzene) electron-rich oxygen atoms ethylene oxide), O-Li+ coordination significantly weakened. Therefore, SPC achieves rapid transport high transference number, importantly, derives unique Li2 O-rich SEI low on surface, therefore enabling stable even down to 10 °C. This work new exploration chemistry solid electrolyte highlights importance solid-state ASSLMBs.

The gel polymer electrolyte (GPE) is a promising substitution for traditional liquid electrolytes. However, GPE still troubled mainly by its sluggish ionic conductivity and inferior interfacial compatibility with electrodes. Herein, phosphorus-modified was fabricated in situ incorporation of black phosphorus (BP) nanosheets into poly(methyl methacrylate) (PMMA) matrix during the self-polymerization monomers. developed exhibited high (1.083 mS·cm–1 at 30 °C), an enhanced Li+ transference number (0.43), wide electrochemical stability window (5.2 V vs Li+/Li), while good thermal improved flame retardancy can also be achieved. Differential scanning calorimeter measurements confirmed that crystallinity PMMA not changed as BP were incorporated. Further investigation proved contained segments effectively immobilized anions to decrease coordination around Li+. As result, ion transport through facilitated, which promoted uniform stripping/plating lithium cycling symmetry cell.
