Anode-free batteries (AFBs) are impressive and recent phenomena in the era of energy storage devices due to their high density relative ease production compared traditional Lithium metal (LMBs). However, dendrite formation during plating stripping low coulombic efficiency (CE) main challenges that impede practical implementation these batteries. Here we report an extremely stable dual-salt electrolyte, 2M LiFSI+1M LiTFSI (2FSI+1TFSI)) DME/DOL (1:1, v/v), system comparison single salt 3M...

Abstract Rechargeable Lithium‐sulfur batteries (LSBs) have been considered as a potential candidate for next‐generation energy storage technologies because of ultrahigh‐energy density (2600 Wh kg −1 ) and being lightweight. However, the practical applications LSBs are currently limited by lithium polysulfides (LiPSs) shuttle, continuous electrolyte decomposition, anode corrosion. These challenges mainly related to cathode structure framework, reactive nature anode, redox reactions occurring...

The utilization of an anode-free lithium-metal battery (AFLMB) is pivotal in meeting the high-energy-density demand for portable electronic devices and vehicles. However, dendritic growth lithium (Li) continuous SEI formation on Copper (Cu) current collector limits lifetime a cell. Here we report effect milled Al2O3/polyacrylonitrile (PAN) composite layer (AOP) coated Cu, as AOP@Cu, to encourage compact smoother Li+ deposition extracted from NMC (333) cathode. excellent wettable nature AOP...

Anode-free lithium–sulfur batteries (AFLSBs) show a surprisingly prolonged cycle life 2-fold higher than anode-free lithium metal batteries. The principal difference is the presence of an intrinsic polysulfide (PS) shuttle between electrodes in AFLSBs. However, underlying mechanism for impact PS redox species on electrochemical performance AFLSBs not clearly understood. Herein, we investigate role retrieving inactive compensating inventory loss using titration gas chromatography, thereby...

Designing a MoS2 catalyst having large number of active sites and high site activity enables the catalytic toward hydrogen evolution reaction to be improved. Herein, we report synthesis low-cost catalytically immobilized single molecular molybdenum disulfide on carbonized polyacrylonitrile (MoS2-cPAN) electrocatalyst. From extended X-ray absorption fine structure spectra analysis, found that as-prepared material has no metal-metal scattering it resembles with state. Meanwhile, size been...

The low capacities of commercial Li ion batteries and cycle instabilities amorphous metal sulfide based impose constraints on their utilization for large-scale energy storage. We report here the acid-free, room-temperature (RT), solution-based synthesis a chalcogenide–carbonaceous hybrid aerogel, termed as "chalcocarbogel", comprising molybdenum (MoSx) graphene oxide (GO). chalcocarbogel is nanoparticle-aggregated, porous, gel consisting Mo3S13 Mo2S12-like structures determined by...

While Li-ion batteries (LIBs) are a leading energy storage technology, their densities limited by the low capacity of conventional intercalation cathodes, driving interest in high energy-density Li-S that make use conversion chemistry. Achieving capacity, reversibility, and cycle stability, controlling volume changes during charge-discharge process, however, remains challenging. Here, we present porous, amorphous, sulfide-based MnxMo3S13 chalcogel, which concurrently offers stability. The...

Abstract Defects in deposited lithium (Li) severely cause dendrite growth and promote reactions between Li electrolytes, resulting active loss anode‐free metal batteries (AFLMBs). Herein, potassium underpotential deposition (K‐UPD) is systematically established to heal defective create a K‐Cu bimetallic interface, facilitating uniform bulk deposition. The K‐UPD at potential of ≈1.0 V, higher than the equilibrium potentials K⁺ (0.1 V) Li⁺ (0.0 V), significantly lowers nucleation barrier...

Abstract Despite large theoretical energy densities, metal‐sulfide electrodes for storage systems face several limitations that impact the practical realization. Here, we present solution‐processable, room temperature (RT) synthesis, local structures, and application of a sulfur‐rich Mo 3 S 13 chalcogel as conversion‐based electrode lithium‐sulfide batteries (LiSBs).
