General description
1,1,2,2-Tetrachloroethane (TeCA) is a chlorine containing hydrocarbon solvent useful for dissolution of cellulose acetate, fat, waxes, greases, rubber and sulfur. It is widely used in the manufacturing of polymers. Among the chlorinated hydrocarbons, it has the highest solvent power.
Application
1,1,2,2-Tetrachloroethane may be employed as a solvent additive for 2,2′,7,7′-tetrakis-(N,N-di-p-methoxyphenyl-amine)9,9′spiro-bifluorene (Spiro-OMeTAD). Spiro-OMe TAD is a triarylamine-based organic p-type organic hole transport material (HTM) employed in solid-state dye-sensitized solar cells.

Polysulfide anions are endowed with unique redox properties, attracting considerable attentions for their applications in alkali metals-sulfur batteries. However, the employment of these anionic species in redox catalysis for small molecule synthesis remains underdeveloped due to their moderate-poor electrochemical potential

Performance decline in Li-excess cathodes is generally attributed to structural degradation at the electrode-electrolyte interphase, including transition metal migration into the lithium layer and oxygen evolution into the electrolyte. Reactions between these new surface structures and/or reactive oxygen species in
