Abstract Ultrathin all‐solid‐state electrolytes with an excellent Li + transport behavior are highly desirable for developing high‐energy‐density solid‐state lithium metal batteries. However, how to balance the electrochemical performance and their mechanical properties remains a huge challenge. Herein, ultrathin solid electrolyte membrane thickness of only 3 µm weight 11.7 g m −2 is well constructed by integrating individual functionalized organic inorganic modules. Impressively, optimized...
A simple and environmentally friendly self-assembly process of oppositely charged polymer PEI inorganic oxide SiO2 was demonstrated for the construction an ultrathin layer on surface PE separator. The XPS, FT-IR, SEM, EDS characterizations give clear evidence successful without significantly increasing thickness sacrificing pristine porous structure This improves a variety crucial properties separator such as electrolyte wetting, uptake, thermal stability, ionic conductivity, Li+...
A simple layer-by-layer (LbL) self-assembly process of poly(acrylic acid) (PAA) and ZrO2 was applied to construct functional ultrathin multilayers on polyethylene (PE) separators without sacrificing the excellent porous structure separators. Such PAA/ZrO2 LbL-modified PE possess good electrolyte wettability, uptake, high ionic conductivity large Li+ transference number. More importantly, top layer LbL would affect dissociation formation solid interphase (SEI) in half-cells. Compared with...
Lithium anodes suffer from severe safety problems in liquid electrolyte systems that result an unstable Li plating/stripping process and dendrite growth, leading to rapid degradation of metal batteries. A polyethylene (PE)-supported gel polymer (GPE) with excellent uptake/retention capability was simply prepared this paper by the construction cross-linked networks (PNs) on surface a poly(ethylenimine)-primed PE separator stabilize lithium anode. The highly delocalized negative charge...
Silicon-based anodes are attracting more interest in both science and industry due to their high energy density. However, the traditional polymeric binder carbon additive mixture cannot successfully accommodate huge volume change maintain good conductivity when cycling. Herein, we report a multifunctional (PPTU) synthesized by cross-linking of conducting polymer (PEDOT:PSS) stretchable poly(ether-thioureas) (PETU). The could be curved on surfaces nanosilicon particles, forming an...
Abstract The reliable operation of Li metal batteries suffers from cathode collapse due to high‐voltage cycling, interfacial reactivity the deposits, self‐discharge at elevated temperatures, as well power output deterioration in low‐temperature scenarios. In contrast individual electrode optimization, herein, a hetero‐layered separator with an asymmetric functional coating on polyethylene is proposed response aforementioned issues: On face‐to‐cathode side, hybrid layer molecular sieve and...
Layered LiNi1-x-yCoxMyO2 (M = Mn or Al) is a promising cathode material for lithium-ion batteries due to its high specific capacity and acceptable manufacturing cost. However, the polycrystalline suffers from disordered orientation of primary particles poor geometric symmetry secondary particles, which severely hampers migration Li+ ions. Furthermore, resulting anisotropy accelerates disintegration particle structure, significantly affecting electrochemical performance cathode. In spite less...
This research develops a simple template assisted sol-gel process for preparing porous TiO2 high performance humidity sensor. Tetraethyl orthosilicate (TEOS) as was directly introduced into sol formed by the hydrolysis and condensation of titanium alkoxide; following calcination led to formation TiO2-SiO2 composite, selective removal SiO2 dilute HF solution structure in TiO2. The resulting TiO2-based sensor exhibits sensitivity linear response wide relative (RH) range 11%-95%, with an...
The composite of tungsten-doped SnO2 and reduced graphene oxide was synthesized through a simple one-pot hydrothermal method. According to the structural characterization composite, tungsten ions were doped in unit cells tin dioxide rather than simply attaching surface. Tungsten-doped situ grown on surface sheet form three-dimensional conductive network that enhanced electron transportation lithium-ion diffusion effectively. issues agglomeration volume expansion could be also avoided because...
Abstract Despite their potential as post lithium‐ion batteries, solid‐state Li‐metal batteries are struggling with insufficient electrochemical sustainability and ambient operation limitations. These challenges mainly stem from lack of reliable electrolytes. Here, a new class single‐ion conducting quasi‐solid‐state soft electrolyte (SICSE) for practical semi‐solid (SSLMBs) is demonstrated. The SICSE consists an ion‐rectifying compliant skeleton nonflammable coordinated electrolyte....
