Solid polymer electrolyte with in-situ generated fast Li+ conducting network enable high voltage and dendrite-free lithium metal battery

Are Polymer‐Based Electrolytes Ready for High‐Voltage Lithium Battery Applications? An Overview of Degradation Mechanisms and Battery Performance

“…[166] In context, PAN and PVdF (and its derivates such as P(VdF-HFP) (poly(vinylidene fluoride)-co-hexafluoropropylene) and P(VdF-TrFE) (poly(vinylidene fluoride-co-trifluoroethylene)) were also used in CPEs and HSEs (Table 4). [30,43,[167][168][169][170][171][172][173][174] In GPEs, the electrochemical stability may be limited by the choice of the solvent or plasticizer. Glyme-based electrolytes bear an oxidation potential at approximately 4 V versus Li/Li + , coinciding with the low oxidative stability of polyethers, [95] whereas carbonate electrolytes are stable up to 5 V versus Li/Li + .…”

The multicomponent synergistic effect of a hierarchical Li0.485La0.505TiO3 solid-state electrolyte for dendrite-free lithium-metal batteries

“…[47][48][49] Moreover, it can also depress the electron transport from the Li metal to the electrolyte and protects the Li metal anode interface. [50][51][52] Based on these advantages, the formation of LiF in the interphase may lead to the dendrite-free operation of the electrode. 53 In order to further confirm the chemical composition of the solid electrolyte interface, the C 1s spectra on the lithium metal surface of the three batteries were analysed (Fig.…”

Environmental Impact Assessment of Solid Polymer Electrolytes for Solid‐State Lithium Batteries

“…[ 41 ] A PAN/LiTFSI electrolyte is selected as a representative example. [ 30 ] Polycarbonates are also interesting given their high dielectric constant that facilitates Li salt dissolution. The oxygen atoms in the carbonyl and alkoxy group in PC weakly coordinate with Li + , yielding large t Li + values.…”

“…[ 44 ] It is worth to note that this work quantifies the environmental impacts of six different SPE designs generally composed of a polymer matrix and the LiTFSI salt. However, due to data scarcity, the majority of the analyzed SPE designs is extracted from manuscripts focused on the development of hybrid electrolytes containing a polymeric matrix, a salt, and a reinforcing filler such as Li 0.33 La 0.557 TiO 3 (for PEO), [ 38 ] SiO 2 (for PAN), [ 30 ] Li 1.5 Al 0.5 Ge 1.5 (PO 4 ) 3 (for PPC), [ 31 ] Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 (for PVDF), [ 42 ] and Li 1.5 Al 0.5 Ge 1.5 (PO 4 ) 3 (for PCL). [ 43 ] Accordingly and for the sake of comparison, the samples not containing inorganic fillers have been solely selected to construct the LCI (these samples have been mostly synthesized as a reference for the obtained new materials).…”

“…The amount of electrolyte used in common coin cells (13 mm in diameter) was first considered as a possible FU. However, as the thickness varied from a minimum of 30 μm for the PAN electrolyte, [ 30 ] to the 200 μm of the PPC electrolyte, [ 31 ] notable differences on the amount of SPE were observed. Therefore, to normalize the environmental impacts, one gram (1 g) of SPE was set as FU.…”
