“…39 A systematic study on the electrochemical stability of electrolytes at various temperatures is important. The specic decomposition potentials of some signicant electrolytes are summarized in the literature; [65][66][67][68][69][70] these studies have shown that solvent systems, type of salt, and working electrodes all affect the electrochemical stability window.…”

“…It will also not generate toxic or dangerous products when exposed to air and water, indicating that NaDFOB may be a prospective Na salt for application in high performance electrolytes for future SIBs. 271 A new high-voltage electrolyte was developed from NaClO4 in mixed ethyl methanesulfonate (EMS) and FEC. 272 The anodic stability of this electrolyte could be increased to 5.6 V vs. Na + /Na, which is higher than that of the PC-based electrolyte of 4.5 V. Moreover, the EMS-based electrolyte had a slightly higher ionic conductivity of 6.3 mS cm ─1 at 25 o C. In this high-voltage electrolyte, the 4.0 V positrode of Na[Ni0.25Fe0.5Mn0.25]O2 was found to have much improved electrochemical performance.…”

Name., 2013, 00, 1-3 | 1 Electrolyte is a key component of electrochemical energy storage (EES) devices and its properties greatly affect the energy capacity, rate performance, cyclability and safety of all EES devices. This article offers a critical review of recent progresses and challenges in electrolyte research and development particularly for supercapacitors and supercapatteries, recharegable batteries (such as lithium-ion and sodium-ion batteries), and redox flow batteries (including fuel cells in a broad sense). The review will focus on liquid electrolytes, particularly aqueous and organic electrolytes, ionic liquids and molten salts. Influences of electrolyte properties on the performances of different EES devices are discussed in detail.

“…To improve the coulombic efficiency of the current SIBs, NaDFOB salt was tested with EC/DMC solvent. 382 The salt was prepared from the reaction of sodium oxalate ( Figure 34e). In this test, the NaDFOB-based electrolyte exhibited a high coulombic efficiency (close to 100%) and long cycle life with low capacity fade.…”

Considering the natural abundance and low cost of sodium resources, sodium-ion batteries (SIBs) have received much attention for large-scale electrochemical energy storage. However, smart structure design strategies and good mechanistic understanding are required to enable advanced SIBs with high energy density. In recent years, the exploration of advanced cathode, anode and electrolyte materials, as well as advanced diagnostics have been extensively carried out. This review mainly focuses on the challenging problems for the attractive battery materials (i.e. cathode, anode and This article is protected by copyright.
