“…Many CSEs have low ionic conductivity at room temperature so they need to work at 60 °C. 39–41 The tensile strength of other CSEs at room temperature is often lower than 1 MPa, and the mechanical strength at high temperatures will be greatly reduced, resulting in a lower CCD. 42–44 The inability to balance lithium-ion conductivity and mechanical strength is a common problem in CSEs.…”

“…40,41 Besides, the continuous organic-inorganic hybrid interface can promote lithium salt dissociation and form a fast lithium ion conducting path owing to the Lewis-acid effect. 42,43 More importantly, the piezoelectric effects of BaTiO 3 alleviate the over-deposition phenomenon of Li + -ions by generating an instantaneous piezoelectric field at the protrusion sites. 25,26 Compared with the existing reports of LLTObased or PEO-based electrolytes (Table S1 †), the performance of the as-prepared BP@LPFL solid electrolyte is the best.…”

“…[ 26 ] Unfortunately, the ionic conductivity enhancement is still limited, because the obtained composites are fabricated by incorporating above powders into polymer electrolytes, in which these incorporated powders are prone to aggregate and precipitate along with solvent volatilization in the film‐forming process, leading to heavy barriers for continuous ion conduction. [ 27–29 ] In addition, the randomly distributed powders in polymer electrolytes fail to provide strong support for lithium dendrite suppression.…”

A structural unit showing a specific function can serve as a functional unit, ranging from atom/molecule system to microscale object. [3] Self-assembly refers to the fact that functional units spontaneously form well-ordered structures, which is ubiquitous in nature, like high-strength nacre, highly anisotropic and strong muscles, self-cleaning lotus effect. [4][5][6][7] The secret of these unique properties is the well-ordered structures formed by self-assembly process. Inspired by this, self-assembled artificial materials with revolutionary performances hold great promise in the field of energy storage and conversion. [8][9][10] In this regard, the incorporated ionic conductors in composite polymer electrolytes can be considered as functional units, which have been used to improve electrochemical properties, structural stability, and mechanical robustness. [11][12][13] Conventionally, the most incorporated ionic conductors are ceramic particles, such as perovskite-type Li 0.33 La 0.557 TiO 3 (LLTO), [14] garnet-type Li 7 La 3 Zr 2 O 12 (LLZO), [15] NASICON-type Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP), Li 1.5 Al 0.5 Ge 1.5 (PO 4 ) 3 (LAGP). [16] Recently, MOF impregnated with ionic liquid (IL) or liquid electrolyte has been served as a novel ionic conductor due to its internal massive pores, which can provide wellordered ion pathways. [17][18][19][20] And some MOF materials are used as fillers for solid polymer electrolytes to enhance the ionic conductivity. [21] However, these discrete particles in polymer electrolytes usually lead to insufficient ionic conductivity improvement because of the isolated and discontinuous lithium ions channels. [22,23] Based on this, 1D ionic conductors with high aspect ratio have been designed and fabricated for extended ions pathways, such as nanowires, [24] nanofibers, [25] and nanotubes. [26] Unfortunately, the ionic conductivity enhancement is still limited, because the obtained composites are fabricated by incorporating above powders into polymer electrolytes, in which these incorporated powders are prone to aggregate and precipitate along with solvent volatilization in the film-forming process, leading to heavy barriers for continuous ion conduction. [27][28][29] In addition, the randomly distributed powders in polymer electrolytes fail to provide strong support for lithium dendrite suppression.In order to overcome the issues of randomly distributed powders, some researchers pay attention to the spatial arrangement of incorporated ceramics in composite polymer Composite solid electrolytes have attracted significant interest because they overcome the defects of single-component solid electrolytes. However, the discontinuous ion transport and weak mechanical support caused by randomly distributed powders lead to inferior ionic conductivity and poor mechanical strength. Herein, a hierarchically self-assembled metal-organic framework (MOF) network is designed to provide continuous ion transport and mechanical support for composite polymer electrolytes. This unique structure is ac...
