Lithium battery with high energy density and enhanced safety is undoubtedly the ideal choice for consumer electronics electric vehicles. Metal anode such as lithium has been considered most effective way to enhance it provides ultra-high theoretical capacity lowest redox potential. However, due low coulombic efficiency well concerns originated from dendrite issue of lithium, its further commercial utilization hindered. Dendrite growth a common phenomenon in metal electrodeposition while...
Abstract As an indispensable part of the lithium-ion battery (LIB), a binder takes small share less than 3% (by weight) in cell; however, it plays multiple roles. The is decisive slurry rheology, thus influencing coating process and resultant porous structures electrodes. Usually, binders are considered to be inert conventional LIBs. In pursuit higher energy density, many new being developed for specific targets, such as high-voltage (typically, $$\geqslant$$ <mml:math...
The application of solid electrolyte is expected to realize the commercialization high energy density lithium metal batteries (LMBs). While interfacial contact between inorganic and electrodes has become a stumbling block for achieving stable cycling in LMBs. In this work, Li-containing polyethylene oxide (LPEO) was introduced LAGP as buffer layer regulate compatibility reduce impedance, inhibiting side reactions. Moreover, ether-oxygen bond on LPEO chain can coordinate with Li+ guide...
Lithium batteries have been widely used in our daily lives for their high energy density and long-term stability. However, safety problems are of paramount concern consumers, which restricts scale applications. Gel polymer electrolytes (GPEs) compensate the defects liquid leakage lower ionic conductivity solid electrolytes, attracted a lot attention. Herein, 3D interconnected highly porous structural gel electrolyte was prepared with alginate dressing as host material, poly(ethylene oxide)...
The key to realize long‐life high energy density lithium batteries is exploit functional electrolytes capable of stabilizing both voltage cathode and anode. emergence localized high‐concentration (LHCEs) shows great promise for ameliorating the above‐mentioned interfacial issues. In this work, a difluoro(oxalate)borate (LiDFOB) based nonflammable dual‐anion LHCE designed prepared. Dissolving in mixture trimethyl phosphate (TMP) /1,1,2,2‐tetrafluoroethyl‐2,2,3,3‐tetrafluoropropylether (D 2 ),...
Lithium metal batteries (LMBs) have attracted more attention for their high energy densities. Their applications are limited the poor low temperature (LT) cycle performance and growth of dendrite due to root problems Li+ desolvation barrier electrode/electrolyte interface. Here, an electrolyte was prepared using dielectric constant solvents ethyl acetate (EA), 1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropylether (D2), voltage endurance lithium salt difluoro(oxalato)borate (LiDFOB), which...
FeS 2 -C@CTs is synthesized by a template-assisted vulcanization strategy, exhibiting high reversible capacity, excellent rate capability and stable cycling performance toward potassium-ion batteries.
One of the bottlenecks limiting cycling stability high voltage lithium metal batteries (LMBs) is lack suitable electrolytes. Herein, phenyl vinyl sulfone (PVS) proposed as a multifunctional additive to stabilize both cathode and anode interfaces it can be preferentially oxidized/reduced on electrode surfaces. The PVS derived solid electrolyte interphase films not only reduce transition dissolution side, but also suppress Li dendrite spread side. Li||Li symmetric battery with addition...
A nanostructured macromolecular lithium salt electrolyte additive is reported. It can serve as a flexible physical barrier between Li/electrolyte interphase and provide extra Li<sup>+</sup>. Some of its functional groups absorb HF, reducing parasitic reactions at high temperature.
