Anode-free lithium batteries (AFLBs) present an opportunity to eliminate the need for conventional graphite electrodes or excess lithium–metal anodes, thus increasing cell energy density and streamlining manufacturing process. However, their attributed poor coulombic efficiency leads rapid capacity decay, underscoring importance of achieving stable plating stripping Li on negative electrode success this configuration. A promising approach is utilization lithiophilic coatings such as silver mitigate nucleation overpotential Cu current collector, thereby improving process plating/stripping. On other hand, inkjet printing (IJP) emerges a technique modification in batteries, offering fast scalable technology capable depositing both thin films patterned structures. In work, Fujifilm Dimatix printer was used deposit Ag sites aiming modulate interfacial electrochemistry system. Samples were fabricated with varying areas coverage electrochemical performance system systematically evaluated from bare (non-lithiophilic) designed pattern (partially lithiophilic) fully coated film case (lithiophilic). Increasing lithiophilicity resulted lower charge transfer resistance, higher exchange reduced (from 55.75 mV 13.5 case). Enhanced half-cell cyclability also achieved (91.22% CE over 76 cycles Cu, 97.01% 250 case), alongside more uniform deposition fewer macroscopic irregularities. Moreover, our observations demonstrated that surface patterning through could represent innovative, easy strategy provide preferential guide subsequent deposition.

Abstract “Anodeless” electrodes for all‐solid‐state batteries (ASSBs) have been attracting attention as a solution achieving high energy density. Recent studies on anodeless shown improvements in cycle life and density through the stabilization of plated lithium (Li) using Li‐soluble metals (e.g., Ag, Zn, etc.).

Alloy anodes present promising alternatives to alkali metals in solid-state batteries but still face morphological instability upon cycling. Unlike conventional using liquid electrolytes, interfacial evolution between electrolytes and alloy is determined by electrochemistry mechanics. Here, we adapt a classical chemomechanical model for Li metal apply anodes. This allows generalizing principle, namely, the hard soft pairing guide improving stability. Specifically, "hard" (high-shear-modulus) ceramic should be paired with "harder" alloys, while "soft" (low-shear-modulus) polymer favor "softer" alloys. We examine properties of several Li–M alloys (M = Al, Mg, In, Sn, Sb). Consistent Li–Sn anode exhibits flattened morphology Li6PS5Cl electrolyte after Conversely, Li–In evolves extremely rough, indicating dendrite formation. Our work underscores significance tuning mechanical properties, incorporating well-established rules traditional metallurgy.

In quantum dots (QDs), mostly governed by their surfaces, in particular surface chemistry faceting. impact free (SFE) through faceting has already been studied QDs. Here, we introduce dominant representing the structural order surface. particular, propose that realistic QDs attain complicated polyhedral quasi-spherical shapes while keeping dominance a certain type facet. facet determines rates surface-related processes. Therefore, connecting with SFE, trends analogical to bulk material are kept despite lack evident microscopic shape control. To demonstrate applicability faceting, synthesize sets silicon sizes around 5 nm classify them based on increasing SFE corresponding analytic geometrical models, using detailed analysis. Total energies released during oxidation synthesized reach theoretical limit, unlike reference, "large" (>100 nm) nanoparticles, which about 15% less energy. Next, perform comprehensive experimental study dehydrogenation thermal temperature range 25-1100 °C, identifying as key factor determining stability reactivity. four distinctive stages were observed onset temperatures ranging between 140 250 ≈500 650-700 respectively, for SFE-differing samples.

However, achieving compatibility with remains a persistent bottleneck. In this study, we shed light on SnHPO3 tin phosphite and Ni3.4Sn4 intermetallic as novel conversion/alloying anode for all-solid-state using Li6PS5Cl solid electrolyte. The two Sn-based active were nanostructured by ball-milling demonstrate considerable promise application in half-cells. Galvanostatic cycling at room temperature revealed electrochemical behavior based reactions akin those observed batteries. Promisingly, both exhibited satisfying stability, coulombic efficiencies exceeding 97%. These findings indicate that electrolyte is compatible alloying anodes.
