Cryogenic engineering of solid polymer electrolytes for room temperature and 4 V-class all-solid-state lithium batteries

Highly ionic conductive, self-healable solid polymer electrolyte based on reversibly interlocked macromolecule networks for lithium metal batteries workable at room temperature

“…6d). 18,20,41,[49][50][51]53,54,[56][57][58] Even though the initial specic capacity of our LMB is slightly lower than the values of ref. 18 and 41, the specic capacity aer long-term cycling (200 and 300 cycles) is comparable to those described in the two papers, which also demonstrates the superior capacity retention of the LMB developed in this work.…”

“…5c and d). In particular, the ionic conductivity of RILNs-3/1-LiPF 6 at 25 C is up to 6.97 Â 10 À4 S cm À1 , which is one of the best among the reported values at ambient temperature 18,22,24,[39][40][41][44][45][46][47][48][49][50][51][52][53][54] (Fig. 5e).…”

PEO composite solid polymer electrolytes with the synergistic effect of cryogenic engineering and trace BP nanosheets for nearly room temperature and 4 V class all-solid-state lithium batteries

“…Furthermore, to strengthen the ionic conducting process apart from the BP/PEO interface region, cryogenic engineering is utilized to impede the growth of PEO crystal regions and maintain the size of PEO crystal regions below the critical size. 37 A fine PEO crystal structure can inhibit coarse crystallization and expose more PEO polymer segments to facilitate the dissolution and good distribution of LiTFSI.…”

Optimizing Li1.3Al0.3Ti1.7(PO4)3 Particle Sizes toward High Ionic Conductivity

“…Lithium-ion batteries (LIBs) are the most widely used energy storage devices nowadays . Generally, LIBs require a liquid electrolyte consisting of lithium salts and organic solvents for ion conduction. , However, electrolyte leakage and safety problems caused by short circuits due to lithium dendrites can occur in liquid batteries. − Compared to liquid electrolytes, solid-state electrolytes (SSEs) have the advantages of inhibiting lithium dendrites, nonflammability, and high-voltage compatibility. − As an essential material for solid-state batteries, SSEs can be divided into oxide, polymer, and sulfide electrolytes. − However, polymer electrolytes have difficulty achieving an ionic conductivity of 10 –4 S cm –1 at room temperature, which is still a considerable distance from liquid electrolytes . On the other hand, sulfide electrolytes are very demanding to prepare as they are susceptible to moisture .…”
