For example, recently, a popular flame retardant, trimethyl phosphate (TMP) was used as the sole solvent as fire-extinguishing organic electrolytes for rechargeable batteries (Fig. 10(a)) [85]. In dilute salt electrolyte, i.e., 1.0 M LiN(SO2F)2 (LiFSA) dissolved in TMP, the many ...
The ideal electrolyte for the widely used LiNi0.8Mn0.1Co0.1O2 (NMC811)||graphite lithium-ion batteries is expected to have the capability of supporting higher voltages (≥4.5 volts), fast charging (≤15 minutes), charging/discharging over a wide temperature range (±60 degrees Celsius) ...
PROBLEM TO BE SOLVED: To provide an energy storage device including a catholyte material that improves total ionic conductivity of a positive electrode to enable high mass loading of active material, rapid charge/discharge, and a wide range of operating temperatures. A positive electrode region is...

For example, it is the energy gapEgbetween the highest occupied molecular orbital and thelowest unoccupied molecular orbitalof a liquid electrolyte that determines thethermodynamic stability. The selection of electrolyte for the Li-Ionbatteriesis...

Solid electrolytes are crucial for the development of solid state batteries. Among different types of solid electrolytes, poly(ethylene oxide) (PEO)-based polymer electrolytes have attracted extensive attention owing to their excellent flexibility and easiness for processing. However, their relatively low...
the deposited Zn, thus reducing the charge/discharge effect of the Zn anode. As a result, the SEI film can stabilize the Zn anode in aqueous and/or non-aqueous electrolytes and improve the service life of Zn batteries [25,26,27,28]. For an ideal SEI film, it should have the ...
Then, interphase manipulation via theparental electrolyte is summarized in terms of electrolyte engineeringstrategies, such as the solvent/salt selection, the concentrationeffect, and the functional additive screening to build a more stableinterphase layer for desirable electrochemical reversibility. Finally,...
Proper selection of the solvent is a primary consideration for constructing SSEs or HSEs for Li-S batteries. When a supporting salt is introduced, the Li2Sx dissolution can be finely tuned according to the coordination effect or the common ion effect. At low concentration, the dissociated ions ...
For example, the types of electrolytes commonly investigated in Zn–air batteries are: aqueous electrolyte, ionic liquid electrolyte, and the polymer electrolyte. Mg–O2 battery; ionic and aprotic electrolytes and solid-state polymer electrolytes. In fuel cells; polymer, ceramic electrolytes and ...
