Sodium‐Ion Pump Enhanced Composite Sodium Anode Toward Fast‐Charging and Practical N/P Ratio Solid‐State Sodium Metal Batteries

Advanced Energy Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 23, 2025

Abstract Solid‐state sodium metal batteries (SSSMBs) employing NASICON‐type solid‐state electrolytes and anodes promise enhanced safety high‐energy density, yet the poor anodic interface compatibility induced growth of Na dendrites excessive consumption still hinder their application. In this work, a 3D porous carbon‐supported ultrathin anode with superionic conductivity high diffusivity is designed on surface NASICON electrolytes, which serve as sodium‐ion pump to improve sodium‐ion‐transfer kinetics. The fast ion/electron transfer within composite effectively solved problem rapid + local charge accumulation at interface, thereby achieving dendrite‐free deposition. A critical current density 3.5 mA cm −2 long cycling life 6000 h 0.2 are achieved for symmetrical cells. Coupled 3 V 2 (PO 4 ) cathode, full cells exhibit high‐capacity retention 90.2% after 5100 cycles 10 C. Most importantly, SSSMBs using limited paired 17.3 mg cathode (1.05 negative/positive capacity ratio) deliver an outstanding 97% 100 cycles. This work demonstrates promising toward development practical sustainable high‐performance SSSMBs.

A Novel Anion Receptor Additive for ‐40ºC Sodium Metal Batteries by Anion/Cation Solvation Engineering

Angewandte Chemie, Journal Year: 2024, Volume and Issue: 137(1)

Published: Oct. 17, 2024

Abstract Sodium metal batteries, known for their high theoretical specific capacity, abundant reserves, and promising low‐temperature performance, have garnered significant attention. However, the large ionic radius of Na + sluggish transport kinetics across interfacial structure hinder practical application. Previous reviews rarely regulated electrolyte performance from perspective anions, as important components electrolyte, regulation mechanism is not well understood. Herein, a novel anion receptor additive, 4‐aminophenylboronic acid pinacol ester (ABAPE), proposed to weaken coupling between anions cations accelerate kinetics. The results calculations X‐ray photoelectron spectroscopy with deep Ar‐ion etching demonstrate that introduction this additive alters solvation , reduces desolvation barrier forms stable dense electrode‐electrolyte interface. Moreover, ABAPE hydrogen bonds (−NH ⋅ O/F) H 2 O/HF, effectively preventing hydrolysis NaPF 6 stabilizing acidic species. Consequently, Na||Na symmetric cell exhibits excellent long‐cycle 500 h at 1 mA cm −2 0.5 mAh . 3 V (PO 4 ) (NVP) addition maintains capacity retention 84.29 % C after 1200 cycles presents no decay over 150 −40 °C.
