Abstract While aqueous zinc metal batteries (AZMBs) have shown great promise for large‐scale energy storage, a series of interfacial side reactions derived from the decomposition active water molecules in Zn 2+ solvation structures seriously hinder practical application AZMBs. Recently, regulating electrolytes has been proven to be effective alleviating reactions. Advanced characterization techniques probe provide powerful tools comprehensively understanding underlying relationship between...
Garnet-type Li6.75La3Zr1.75Ta0.25O12 (LLZTO) is a promising solid-state electrolyte (SSE) because of its fast ionic conduction and notable chemical/electrochemical stability toward the lithium (Li) metal. However, poor interface wettability large resistance between LLZTO Li anode greatly restrict practical applications. In this work, we develop an in situ chemical conversion strategy to construct highly conductive Li2S@C layer on surface LLZTO, enabling improved interfacial anode. The...

LiAlH4, characterized by high hydrogen capacity and metastable properties, is regarded as a promising source under mild conditions. However, its reversible regeneration from dehydrogenated production hindered thermodynamically kinetically. Herein, we demonstrate an active Li–Al–Ti nanocrystalline alloy prepared melt spinning cryomilling to enable directly synthesizing nano-LiAlH4. Due the non-equilibrium preparation methods, grain/particle size of was reduced, stress defects were introduced,...
To achieve large-scale hydrogen storage for growing high energy density and long-life demands in end application, the 2LiBH4-MgH2 (LMBH) reactive hydride system attracts huge interest owing to its capacity thermodynamically favorable reversibility. The sluggish dehydrogenation kinetics unsatisfactory cycle life, however, remain two challenges. Herein, a bimetallic titanium-niobium oxide with two-dimensional nanoflake structure (2D TiNb2O7) is selected elaborately as an active precursor that...
Owing to anionic oxygen redox, cathode materials containing lithium-rich oxides (LROs) exhibit a large discharge capacity exceeding 300 mAh/g. This makes them viable choices for fabrication of future development lithium-ion batteries with an energy density 500 Wh/kg. However, O redox is irreversible, resulting in voltage/capacity fade precipitation lattice during cycling. In this work, we review the mechanism role intrinsic microstrains and potential defects strategies achieve reversible...
To solve the problem of large-scale hydrogen energy storage, 2LiBH4-MgH2 has been widely studied owing to its high storage capacity. However, sluggish kinetics and insufficient reversibility impeded practical application. Herein, layered bimetallic titanium-niobium oxide (2D-TiNb2O7) nanoflake was added introduce highly dispersed ultra-fine TiB2 NbB2 in Li-Mg-B-H system as catalysts. As a result, excellent kinetic properties with long-term cycling stability were achieved. For LMBH-5TNO 5 wt%...
The specific capacity of Li- and Mn-rich layered oxide (LMROs) cathodes can be enhanced by the oxidation lattice oxygen at high voltages. Nevertheless, an irreversible loss emerges with cycling, which triggers interlocking surface/interface issues results in fast deterioration cycling performance. Herein, we prepare a surface modified LMRO electrode one step doctor-blade casting introducing benzoquinone species DBBQ redox couple. electrochemical test shows that DBBQ-modified has reversible...
We report a microfabricated microbial fuel cell (MFC) that produces high power density using Geobacteraceae-enriched mixed bacterial culture.The MFC features 4.5-L anode/cathode chambers defined by 20-m-thick photo-definable polydimethylsiloxane (PDMS).The short proton diffusion length (20 m) in the anode lowers electrolyte resistance and consequently enhances generation.A maximum current of 16.3 mA/cm 3 2.3 mW/cm are achieved.The start-up time is only 2 days for generation.The was operated...
