UiO‐66‐NH₂@67 Core–Shell Metal–Organic Framework as Fillers in Solid Composite Electrolytes for High‐Performance All‐Solid‐State Lithium Metal Batteries

Abstract

Benefiting from employing solid composite electrolytes (SCEs), all‐solid‐state lithium‐ion batteries (ASSLBs) are recognized to occupy with high energy density and safety. Herein, a polymer‐based SCE membrane (SCE‐66@67) with core–shell structured metal–organic frameworks (MOFs) (UiO‐66‐NH2@67) as the fillers is presented. The SCE has combined the advantages of the two kinds of MOFs and shows a satisfying ionic conductivity (2.09 × 10−4 S cm−1 at 60 °C) and a wide electrochemical stability window of ≈5.0 V. The full cell (Li/SCE‐66@67/LiFePO4) also maintains a high capacity of 120.9 mAh g−1 at 3 C. This research might help to promote the development of future SCEs for ASSLBs.

Solid-state composite electrolytes: turning the natural moat into a thoroughfare

“…The LFP/Li SSBs with the resulting SCEs could deliver a discharge capacity of 120.9 mA h g −1 and the capacity retention is 98.13% after 80 cycles at 0.2C. 110 The linker used to synthesize the MOFs can introduce various kinds of functional groups in the final resulting product and endow some functional characteristics to the MOF filler. For example, Ahn et al used bio-material-based adenine as a linker to synthesize bio-MOFs with naturally abundant functional groups.…”

Performance Analysis and Optimization of SOFC/GT Hybrid Systems: A Review

“…Under the background of the strategic goal of "carbon peak before 2030 and carbon neutrality before 2060", creating a clean, low-carbon, safe, and efficient energy system is attracting the attention of an increasing number of researchers [1][2][3][4][5]. Since alkali metal ion batteries [3,[5][6][7], solid state batteries [8][9][10][11][12][13], and lithium metal batteries [14][15][16][17][18], however, are all energy storage technologies, developing new and clean energy conversion technologies is still an urgent requirement around the world [2,19]. The solid oxide fuel cell (SOFC) transforms the chemical energy of fuel and oxidizer directly into electrical energy; it can be coupled with gas turbines (GT) and steam turbine to create an effective and clean hybrid power system because of its advantages in high power generation efficiency, high waste heat level, and low pollution [20][21][22].…”
