of serious interfacial reactions, Li dendrite growth, large interfacial resistance, etc. [2] To overcome these issues, a chemically/ electrochemically stable, mechanically compatible, Li + -conductive and electronically insulating solid electrolyte interphase (SEI) layer needs to be formed on electrolyte/Li interface.Here in this work, a sulfide and polymer composite solid electrolyte (CSE) is developed to overcome these issues. More specifically, lithium polysulfidophosphate (LPS) is introduced as an additive for poly(ethylene oxide) (PEO)-based CSEs to synergistically react with lithium metal for in situ formation of an ideal SEI layer in Li-metal-anode ASSB. PEO itself has various drawbacks, including low Li + conductivity (10 −6 S cm −1 at room temperature), [3] narrow electrochemical window, [4] and intrinsic soft mechanical properties causing small critical current densities (CCDs). [5] Multiple approaches have been employed to solve these problems, including co-polymerization, [6] polymer blend, [7] introduction of secondary phases as inert fillers (e.g., BaTiO 3 /Al 2 O 3 /TiO 2 /SiO 2 / CeO 2 ), [8] Li + conducting active fillers (e.g., NASICON, garnet, perovskite, and sulfides), [9] and plasticizers (e.g., propylene carbonate, ethylene carbonate, and succinonitrile). [10] For the PEO-lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) system, the interfacial stability issue between polymer-salt and lithium metal cannot be ignored because of the unstable SEI at the interface. [11] During cycling, SEI grows continuously An ultrastable and kinetically favorable interface is constructed between sulfide-poly(ethylene oxide) (PEO) composite solid electrolytes (CSEs) and lithium metal, via in situ formation of a solid electrolyte interphase (SEI) layer containing Li 3 PS 4 . A specially designed sulfide, lithium polysulfidophosphate (LPS), can distribute uniformly in the PEO matrix via a simple stirring process because of its complete solubility in acetonitrile solvent, which is advantageous for creating a homogeneous SEI layer. The CSE/Li interface with high Li + transportation capability is stabilized quickly through in situ formation of a Li 3 PS 4 /Li 2 S/LiF layer via the reaction between LPS and lithium metal to inhibit lithium dendrite growth. A Li/Li symmetric cell with the LPS-integrated CSE exhibits constant and small CSE/Li resistance of 10 Ω cm 2 during cycling, delivering stable cycling for 3475 h at a current density of 0.2 mA cm −2 and a high critical current density of 0.9 mA cm −2 at 60 °C. Impressive electrochemical performance is also demonstrated for LiFePO 4 /CSE/Li all-solid-state batteries with capacity of 127.6 mAh g −1 after 1000 cycles at 1 C.

Superhydrophobic dandelion‐like 3D microstructures self‐assembled from 1D nanofibers of PANI were prepared by a self‐assembly process in the presence of perfluorosebacic acid (PFSEA) as a dopant. The dandelion‐like microspheres (about 5 µm) are composed of uniform Y‐shaped junction nanofibers of about 210 nm average diameter and several micrometers in length, as measured by SEM. The dandelion‐like microstructure is coreless with a hollow cavity, and the shell thickness is about one third of the sphere diameter, as measured by TEM. Since PFESA dopant has a low surface energy perfluorinated carbon chain and two hydrophilic COOH end groups, it has dopant, is a “soft‐template” and brings about superhydrophobic functions at the same time. Moreover, it is proposed that the self‐assembly of PANI 1D nanofibers, driven by a combined interaction of hydrogen bonding, π‐π stacking and hydrophobic interactions, leads to the formation of the 3D microstructures.magnified image

A superhydrophobic polyaniline (PANI)‐coated fabric was prepared by in‐situ doping polymerization in the presence of perfluorosebacic acid (PFSEA) as the dopant. It is found that the PANI‐coated fabric undergoes a change in wettability from superhydrophobic (doped state) to superhydrophilic (de‐doped state) when it is exposed to ammonia gas. In particular, a reversible wettability of the PANI‐fabric is observed when it is doped with PFSEA and de‐doped with ammonium gas. It is proposed that the coordination effect of the pore structure of the polyester fabric, low surface energy of the PFSEA dopant, and reversible doping/dedoping characteristics of PANI results in the reversible wettability of the PANI‐coated fabric from superhydrophobicity to superhydrophilicity. Moreover, the tactic used here may provide a new method to monitor the toxic gas.magnified image
