Electrolyte solvation chemistry for lithium–sulfur batteries with electrolyte-lean conditions

Advanced energy materials for flexible batteries in energy storage: A review

“…CNT paper-based current collectors have been used to support various active materials, such as V 2 O 5 , 245 LiFePO 4 , 246 Li 4 Ti 5 O 12 , 247 and NCM. 248 The recent arise of interests in high-energy Li-S batteries have triggered tremendous efforts to the development of sulfur cathodes, 249,250 electrolytes, 45 and lithium metal anodes. 251 Peng et al 241 demonstrated a flexible CNT-based sulfur electrodes to increase sulfur contents, curtail passivation layers, as well as promote redox kinetics of sulfur interconversions ( Figure 13B).…”

“…To achieve desired energy density in the large format cells, thick electrode, lean electrolyte, low porosity, and minimum inactive materials are pursued. [45][46][47][48] However, flexible cells need to bear significant geometric deformation, which leads to component sliding and moving. Therefore, rational design of the flexible battery components and structures is prerequisite for flexible batteries to withstand acceptable deformation.…”

Ambiguities in solvation free energies from cluster-continuum quasichemical theory: lithium cation in protic and aprotic solvents

“…1 Knowledge of Li + solvation energy in different solvents especially aprotic is crucial for the development and optimization of current and future high capacity energy storage devices such as Li-ion, Li-metal, Li-S, Li-O 2 batteries. [2][3][4][5][6] For rationalization and careful tuning of these industryappreciated processes, the quantitative measure of the ionic solute -solvent interplay, the solvation Gibbs free energy of ions, ∆G solv , is introduced. In contrast to the solvation thermodynamic functions of the neutrals accessible via a combination of the sublimation(vaporization) and solubility equilibrium constants from mass-spectrometric, calorimetric and chemical analysis studies, these characteristics of ionic solutes are challenging to obtain.…”

The rechargeable aluminum-ion battery with different composite cathodes: A review

“…PS dissolution and the determination of the power capability of the cells are dependent on the liquid electrolyte. A facile approach to suppress the polysulfide redox shuttle and improve the Li deposition morphology is to incorporate additives to the electrolyte [48]. The low coulombic efficiency of lithium cycling could be solved by adding LiNO 3 , however, it undergoes gradual consumption on the Li anode and cathode and its strong oxidative property causes safety issues [49].…”
