In situ gelation adds fresh potential for conventional liquid electrolytes in applications to lithium metal batteries.
A dendrite-free Li deposition strategy is developed with a composite separator of MnCO3 coated porous polypropylene. Mn2+ ions are preferentially reduced to form Mn nanoparticles on anodes, which helped reduce the nucleation overpotential and achieve bulky grains. When contacts metal anode directly, an in situ artificial solid electrolyte interphase passivating layer was created from reaction metal, liquid electrolyte. anodes show significantly improved stability for more than 2000 h...
Expression of chirality in the highly ordered assembly structures various types natural and synthetic materials is still a mystery. Although surface stresses have been known to widely exist polymer lamellae, how they affect twisting yet an unsolved issue. Here we report inversion lamellar microbial poly(R-3-hydroxybutyrate) copolymers from left-handed right-handed via copolymerization or blending, with molecular crystalline core unchanged. We interpret observed complicated curvature...

Abstract Lithium (Li) metal anodes are regarded as a promising pathway to meet the rapidly growing requirements on high energy density cells, owing their highest gravimetric capacity (3840 mAh g −1 ) and lowest redox potential. The application of Li anodes, however, is still hindered by undesired dendrites formation endless consumption liquid electrolyte due continuous reaction interface electrolyte/Li‐metal without stable solid–electrolyte–interface (SEI) layer. A protection layer formed...
Abstract The application of lithium metal anode, despite being the highest capacity, is hindered by low Coulombic efficiency (CE) and serious dendrites formation. A strategy transition oxides (TMOs) particles coated porous polypropylene (PP) separator developed to regulate deposition behaviors through in situ forming artificial solid electrolyte interface (SEI) passivating layers. By virtue quite solubilities TMOs electrolyte, concentration can be maintained at a constant dissolved reduced...
Abstract In situ forming gel polymer electrolyte (GPE) is one of the most feasible ways to improve safety and cycle performances lithium metal batteries with high energy density. However, in formed GPEs are not compatible high‐voltage cathode materials. Here, this work provides a novel strategy form GPE based on mechanism Ritter reaction. The reaction liquid has advantage appropriate temperature no additional additives. chains cross‐linked by amide groups formation superior electrochemical...
Abstract A series of copolymers are prepared via cationic ring‐opening polymerization with 1,3‐dioxolane (DOL) and trioxymethylene (TOM) as monomers. The crystallization behaviors the can be suppressed by adjusting ratio DOL/TOM. With LiBF 4 a source for BF 3 initiator, copolymer electrolytes (CPEs) in situ inside cells without needing nonelectrolyte catalysts or initiators. ionic conductivities Li + diffusion coefficients () CPEs increase decreasing DOL/TOM certain range. CPE 8/2 has...
ZnO nanoneedle arrays have been grown on a large scale with chemical vapor deposition method at 680 degrees C. Zn powder and O(2) gas are employed as source materials, catalyst-free Si plates used substrates. Energy-dispersive X-ray diffraction analyses show that the nanoneedles almost pure preferentially aligned in c-axis direction of wurtzite structure. The growth mechanism is discussed thermodynamic theory concluded to be result co-effect surface tension diffusion. Photoluminescence...
The recrystallization behavior of poly(ethylene oxide) (PEO) on four amorphous films poly(vinyl alcohol) (PVA), lysozyme (LYSO), poly(vinylpyrrolidone) (PVPY), and poly(acrylic acid) (PAA) was investigated using atomic force microscopy (AFM) transmission electron (TEM). results show that both the degree supercooling PEO/substrate interactions have pronounced influence over growth PEO crystals. A thermodynamic model has been proposed accordingly, in which lamellar orientation is associated...

An asymmetric gel polymer electrolyte with dual functions of immobilizing polysulfides and promoting uniform Li deposition.
White light-emitting InGaN∕GaN diode with an InGaN underlying layer grown on the (0001) sapphire substrate was fabricated by low pressure metal-organic vapor phase epitaxy. The electroluminescence measurements show that emitted white light is composed of blue and yellow lights, centered at around 440 570nm, respectively, for injection current 20mA.
