High ion conductivity based on a polyurethane composite solid electrolyte for all-solid-state lithium batteries

Abstract

Adding inert filler to reduce the coupling effect of functional groups to Li+ and modifying the functional groups to reduce the adsorption of Li+ can lead to high ionic conductivity.

Surface ligands influence the selectivity of cation uptake in polyoxovanadate–alkoxide clusters

“…Lithium is an important resource, with a broad range of uses in pharmaceuticals, 1 greases, 2 and battery technologies. 3–5 Our dependence on this metal is anticipated to increase over the next several decades, 6 requiring improved strategies for the extraction of lithium from natural sources. Unfortunately, the majority of the world's lithium supply is contained in continental brine ( e.g.…”

Polyurethane–P2S5 composite-based solid-state electrolyte assists low polarization and high stability all-solid-state lithium-ion batteries

“…Besides, we find that the battery exhibits a stable charging/discharging platform at different C-rates and no obvious polarization phenomenon, which indicates that the electrolyte prepared by us greatly improves the stability of the battery and enhances the contact between the electrolyte and the electrode, and thus reduces the battery polarization phenomenon. 9 Fig. 4(c) shows the charging/discharging performance of the battery at different C-rates.…”

“…7,8 PU elastomers, one of them, can form good contact with electrodes while having high ionic conductivity. 9 Different from other solid polymer electrolytes, PU molecules have a unique structure of hard and so segments. The hard segment offers the molecule mechanical strength to effectively hinder the growth of the lithium dendrite phenomenon, while the so segment provides a transport path for Li + ions.…”

Polyurethane/Li10GeP2S12 composite electrolyte with high ions transfer number and ions capture for all-solid-state lithium batteries

“…All-solid-state Li-ion batteries (ASSLBs) have been regarded as an alternative to traditional liquid Li-ion batteries (LLIBs) for their higher energy density, better safety, and flame retardancy [1] . The core component of ASSLBs is the solid-state electrolyte (SSE), which is linked to the overall performance of the battery [2] .…”
