Polyaddition enabled functional polymer/inorganic hybrid electrolytes for lithium metal batteries

Abstract

The exploration towards solid electrolytes to replace conventional organic liquid electrolyte paves the way for producing next generation lithium secondary batteries. Herein, a new class of polymer/inorganic hybrid electrolytes (HEs)...

A highly conductive and stable hybrid solid electrolyte for high voltage lithium metal batteries

“…In contrast, the concentration of Li + in the P(VDF-HFP)-Li 10 -50LATP HSE is relatively higher and uniformly distributed without charge accumulation. 49 The current density distribution of P(VDF-HFP)-50LATP and P(VDF-HFP)-Li 10 -50LATP HSEs under 3D and 2D is shown in Fig. 4c, d and video S1.…”

Self‐Repairable and Flexible Polymer Network Electrolyte with Enhanced Lithium‐Ion Conduction for Lithium Metal Batteries

“…Synthesis of 2,2‐bis((3‐butyl‐2,3‐dihydro‐1H‐imidazole‐1‐yl)methyl)propane‐1,3‐diol, TFSI − salt (BPDTFSI) : BPDTFSI was prepared by the anion exchange between 2,2‐bis((3‐butyl‐2,3‐dihydro‐1H‐imidazole‐1‐yl)methyl)propane‐1,3‐diol, bromine salt (BPDBr) and LiTFSI. BPDBr was synthesized according to our previous work [12a] . BPDBr (1.99 g, 3.9 mmol) was dispersed in 20 mL deionized water with stirring for 2 h and then LiTFSI (1.35 g, 4.7 mmol) was added into the solution.…”

Ionic liquid/poly(ionic liquid)-based electrolytes for lithium batteries

“…47,[79][80][81] In PIL-based SPEs, although their ion-conducting groups can provide ion transport sites, the crystalline behavior of the polymer and the ion-polymer coupling relationship still affect the ion transport efficiency. 82,83 Meanwhile, the ionic conductivity of the electrolyte as a whole is also directly influenced by the solvation process of Li + in the PIL electrolyte. 84 The strong interaction of the negatively charged groups with Li + or the weak binding of the positively charged groups to the anion in PILs increases the activation energy of Li + migration and reduces its conductivity.…”
