Metallic Solids

Metallic Solids

Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

Background:

Poly(ethylene oxide) (PEO)-based solid polymer electrolytes (SPEs) face challenges in mechanical strength and ionic conductivity for all-solid-state lithium metal batteries (LMBs).
Improving these properties is crucial for advancing high-performance energy storage devices.

Purpose of the Study:

To design and synthesize novel rigid-flexible coupling network SPEs (RFN-SPEs).
To enhance both mechanical strength and ionic conductivity of SPEs for LMB applications.

Main Methods:

Incorporation of soft poly(ethylene glycol) (PEG) chains with rigid crosslinkers containing benzene structures.
Fabrication of RFN-SPEs utilizing a rigid-flexible coupling network strategy.
Electrochemical testing of symmetrical cells and LMBs with the developed RFN-SPEs.

Main Results:

RFN-SPEs exhibit synchronously improved ionic conductivity and mechanical strength compared to conventional SPEs.
Symmetrical cells demonstrated stable cycling for over 2100 hours at 0.5 mA cm⁻².
Lithium metal batteries (LMBs) using RFN-SPEs achieved stable cycling and high-rate capability.

Conclusions:

The rigid-flexible coupling network strategy effectively enhances the performance of SPEs.
RFN-SPEs are promising electrolyte systems for high-performance all-solid-state lithium metal batteries.
This work provides a new avenue for developing advanced solid-state electrolytes.
