An electrolyte based on fluorinated carbonate solvents was evaluated with high voltage cathode materials at elevated temperature. The theoretically anodic stability of these new electrolytes supported by electrochemical evaluation results using LiNi0.5Mn1.5O4/Li and LiNi0.5Mn1.5O4/Li4Ti5O12 couples. Fluorinated appears to be a suitable candidate for transition metal oxide cathodes (5 V vs. Li+/Li).

Abstract Nonaqueous carbonate electrolytes are commonly used in commercial lithium‐ion battery (LIB).

Fluorides have been identified as a key ingredient in interphases supporting aggressive battery chemistries. While the precursor for these fluorides must be pre-stored electrolyte components and only delivered at extreme potentials, chemical source of fluorine so far has confined to either negatively-charge anions or fluorinated molecules, whose presence inner-Helmholtz layer electrodes, consequently their contribution interphasial chemistry, is restricted. To pre-store on positive-charged...
Recent efforts to improve zinc metal anode reversibility in aqueous electrolytes have primarily focused on tailoring Zn2+ solvation. We propose a complementary approach directly engineer the interphase with help of two co-cations. The designed organic co-cations offer distinct improvements: partially fluorinated pyrrolidinium cation effectively suppresses parasitic reactions such as hydrogen evolution (<6 μA cm−2), while an ether-functionalized ammonium inhibits dendrite formation (almost 10...
Lithium–O2 cells can be considered the “holy grail” of lithium batteries because they offer much superior theoretical energy density to conventional lithium-ion systems. In this study, porous carbon-supported MnO2 nanorods synthesized at room temperature were explored as an electrocatalyst for rechargeable Li–O2 cells. Both high-energy X-ray diffraction and absorption fine-structure analyses showed that prepared exhibited a tetragonal crystal structure (α-MnO2), which has proved one most...

Control of polysulfide shuttling and stabilization lithium anodes are accomplished using a fluorinated electrolyte without cathode confinement or oxidizing additives. The formation lithium-surface SEI with hierarchical compositions suppresses parasitic reactions preserves the anode quality.
With the correlation between Li+ solvation and interphasial chemistry on anodes firmly established in Li-ion batteries, effect of cation–solvent interaction has gone beyond bulk thermodynamic transport properties become an essential element that determines reversibility electrochemistry kinetics intercalation chemistries. As now, most studies are dedicated to Li+, anions carbonate-based electrolytes its possible electrochemical stability such remains little understood. a mirror effort prior...
