Abstract

A composite polymer electrolyte (CPE) based on garnet Li7La3Zr2O12 (LLZO) nanofiber-incorporated PVDF-HFP is reported.

Application of polyamide 6 microfiber non-woven fabrics in the large-scale production of all-solid-state lithium metal batteries

“…The electrochemical stability is an important parameter to evaluate the actual performance of the all-solid-state electrolyte [ 39 ]. The wide electrochemical window generally means that electrolyte can be matched with high-voltage cathodes [ 43 ]. According to the test results in Fig.…”

Toward safer solid-state lithium metal batteries: a review

“…It is accepted that composite electrolytes, including inorganic-polymer composite electrolytes and polymer-polymer composite electrolytes, can be a promising way to tackle the problem of the low shear modulus of SPEs. [20][21][22] In inorganicpolymer composite electrolytes, commonly used inorganic llers are classied into inert llers such as SiO 2 , TiO 2 , and Al 2 O 3 , and active llers which are mainly Li + conductors such as LLZO and LGPS. Both kinds of inorganic llers can improve the mechanical strength of SPEs and impose a certain inhibitory effect on lithium dendrites.…”

Structure‐Controlled Li Metal Electrodes for Post‐Li‐Ion Batteries: Recent Progress and Perspectives

“…In particular, most research has focused on the formation of a very stable SEI on the surface of the Li metal electrode as the most important prerequisite of high performance. [ 16,20,21,24,26,27,41,50,59–64,66,76 ]…”

“…Considering both high current density and areal capacity for the design of high‐energy‐density secondary batteries, one arrives at the conclusion that Li metal cannot be used as a thin foil itself. Therefore, numerous methods for alleviating Li dendrite growth have been proposed, as exemplified i) by the use of functional electrolytes, [ 29,55–58 ] ii) by using polymer electrolytes, [ 59–64 ] iii) modified separator, [ 60,65–70 ] and iv) protective layers. [ 27,71–76 ] However, attempts to modify or improve the performance of Li metal itself have been limited.…”
