Abstract

Aqueous rechargeable sodium-ion batteries (ARSIBs) are highly desirable for the large-scale energy storage due to their inherent high safety and low-cost. Na-Mn-O electrode material has been considered as a promising cathode, yet the redox potential window is still not fully explored and utilized in aqueous rechargeable sodium-ion batteries. Herein, a chemical bonded Na_0.44MnO₂ (NMO) plates are successfully synthesized via a polyvinylpyrrolidone-assisted sol-gel route followed by annealing process. The possibility of utilizing a wider potential window ranging between –0.3 V and 1.0 V vs. Ag/AgCl in mild aqueous electrolyte has been thus demonstrated by using NMO plates as cathodes for the first time. As a result, the as-synthesized NMO plates can deliver a highest initial discharge capacity of 77.2 mA h g^–1 at a current density of 100 mA g^–1, compared with previous Na-Mn-O reports in mild aqueous electrolyte in ARSIBs. Even at a high rate of 500 mA g^–1, it still maintains a large capacity of 35 mA h g^–1 after 1000 cycles, demonstrating its superior cycling stability. In addition, ex situ SEM and TEM-EDX results reveal that there is a newly formed sheet-like layer Na-birnessite Na_0.55Mn₂O₄ · 1.5H₂O on the surface of NMO cathodes, which can provide extra ionmore »« less

Cr{sub 2}O{sub 5} as new cathode for rechargeable sodium ion batteries

Journal Article Feng, Xu-Yong ; Chien, Po-Hsiu ; Rose, Alyssa M. ; ... - Journal of Solid State Chemistry

Chromium oxide, Cr{sub 2}O{sub 5}, was synthesized by pyrolyzing CrO{sub 3} at 350 °C and employed as a new cathode in rechargeable sodium ion batteries. Cr{sub 2}O{sub 5}/Na rechargeable batteries delivered high specific capacities up to 310 mAh/g at a current density of C/16 (or 20 mA/g). High-resolution solid-state {sup 23}Na NMR both qualitatively and quantitatively revealed the reversible intercalation of Na ions into the bulk electrode and participation of Na ions in the formation of the solid-electrolyte interphase largely at low potentials. Amorphization of the electrode structure occurred during the first discharge revealed by both NMR and X-ray diffractionmore »« less

Design of a Single-Ion Conducting Polymer Electrolyte for Sodium-Ion Batteries

Journal Article Liu, Kewei ; Xie, Yingying ; Yang, Zhenzhen ; ... - Journal of the Electrochemical Society

Here, a sodium bis(fluoroallyl)malonato borate salt (NaBFMB) is synthesized. Using a Click thiol-ene reaction, NaBFMB can be photo-crosslinked with a tri-thiol (trimethylolpropane tris(3-mercapto propionate), TMPT) to create a single-ion conducting electrolyte (NaSIE), with all negative charges residing on the borate moieties and anions immobilized through the 3-D crosslinked network. The NaSIE can be prepared either as a free-standing film or through a drop-cast method followed by a photo crosslinking method for an in-situ formation on top of the electrodes. The free-standing film of NaSIE has a high ionic conductivity of 2 × 10^–3 S cm^–1 at 30 °C, and amore »« less

Hydrogen-Bonding Interactions in Hybrid Aqueous/Nonaqueous Electrolytes Enable Low-Cost and Long-Lifespan Sodium-Ion Storage

Journal Article Chua, Rodney ; Cai, Yi ; Lim, Pei Qi ; ... - ACS Applied Materials and Interfaces

Although “water-in-salt” electrolytes have opened a new pathway to expand the electrochemical stability window of aqueous electrolytes, the electrode instability and irreversible proton co-insertion caused by aqueous media still hinder the practical application, even when using exotic fluorinated salts. In this study, an accessible hybrid electrolyte class based on common sodium salts is proposed, and crucially an ethanol-rich media is introduced to achieve highly stable Na-ion electrochemistry. Here, ethanol exerts a strong hydrogen-bonding effect on water, simultaneously expanding the electrochemical stability window of the hybridized electrolyte to 2.5 V, restricting degradation activities, reducing transition metal dissolution from the cathode material,more »« less

Entropy and crystal-facet modulation of P2-type layered cathodes for long-lasting sodium-based batteries

Journal Article Fu, Fang ; Liu, Xiang ; Fu, Xiaoguang ; ... - Nature Communications

Abstract P2-type sodium manganese-rich layered oxides are promising cathode candidates for sodium-based batteries because of their appealing cost-effective and capacity features. However, the structural distortion and cationic rearrangement induced by irreversible phase transition and anionic redox reaction at high cell voltage (i.e., >4.0 V) cause sluggish Na-ion kinetics and severe capacity decay. To circumvent these issues, here, we report a strategy to develop P2-type layered cathodes via configurational entropy and ion-diffusion structural tuning. In situ synchrotron X-ray diffraction combined with electrochemical kinetic tests and microstructural characterizations reveal that the entropy-tuned Na _0.62 Mn _0.67 Ni _0.23 Cu _0.05 Mg _0.07 Timore »« less

“Water‐in‐Salt” Electrolyte Makes Aqueous Sodium‐Ion Battery Safe, Green, and Long‐Lasting

Journal Article Suo, Liumin ; Borodin, Oleg ; Wang, Yuesheng ; ... - Advanced Energy Materials

Abstract Narrow electrochemical stability window (1.23 V) of aqueous electrolytes is always considered the key obstacle preventing aqueous sodium‐ion chemistry of practical energy density and cycle life. The sodium‐ion water‐in‐salt electrolyte (NaWiSE) eliminates this barrier by offering a 2.5 V window through suppressing hydrogen evolution on anode with the formation of a Na ⁺ ‐conducting solid‐electrolyte interphase (SEI) and reducing the overall electrochemical activity of water on cathode. A full aqueous Na‐ion battery constructed on Na _0.66 [Mn _0.66 Ti _0.34 ]O ₂ as cathode and NaTi ₂ (PO ₄ ) ₃ as anode exhibits superior performance at both lowmore »« less
