The stochastic instigation and growth of needle-like microstructures during the charging period in rechargeable batteries can cause hazard short circuit utilization, such that they control state health longevity. Herein, we aim at establishing relationship between solid-mass/empty-space fractions growing electrodeposits elaborate on interrelation structural density with electrodeposition parameters. We initially tackle estimating micro-scale ρMicro behavior through percolation-based image processing copper experiments correlate them to bulk salt concentration C0 as well applied voltage V0. Subsequently, establish a theoretical model for rate microstructures, considering both micro- nano-scale porosity. Since porosity directly correlates their kinetics (i.e., rate) growth, have estimated order ρNano∼[10−4,10−3] via comparing porous ramification modeling frameworks. Consequently, address branching pattern dendritic compute real-time fractal dimension vs explain it terms oscillatory nucleation branching. obtained understanding from correlation voltage, inherent atomic-scale range amorphous electrodeposits, could help tune morphology which be helpful applications avoid enhance

Abstract Anode‐free alkali metal batteries (AFAMBs) are regarded as the most promising candidates for next‐generation high‐energy systems owing to their high safety, energy density, and low cost. However, restricted supply at cathode, severe dendrite growth, unstable electrode‐electrolyte interface result in Coulombic efficiency severely short cycle life. The optimization strategies mainly based on laboratory‐level coin cells, but effectiveness practical‐level is rarely discussed. This review presents a comprehensive overview of recent developments challenges AFAMBs from laboratory toward practicability. First, advances, major challenges, systematically summarized. More significantly, given vast differences battery structures operating conditions, gap between particularly emphasized this review. In addition, failure mechanisms have been outlined key parameters affecting performance identified. Finally, insightful perspectives practical presented, aiming provide helpful guidance subsequent basic research promote large‐scale commercial applications AFAMBs.

Abstract Interest in all‐solid‐state batteries (ASSBs), particularly the anode‐less type, has grown alongside expansion of electric vehicle (EV) market, because they offer advantages terms their energy density and manufacturing cost. However, most ASSBs, anode is covered by a protective layer to ensure stable lithium (Li) deposition, thus requiring high temperatures adequate Li ion diffusion kinetics through layer. This study proposes dual‐seed consisting silver (Ag) zinc oxide (ZnO) nanoparticles for sulfide‐based ASSBs. dual‐seed‐based not only facilitates via multiple lithiation pathways over wide range potentials, but also enhances mechanical stability interface situ formation Ag–Zn alloy with ductility. The capacity retention during full‐cell evaluation 80.8% 100 cycles when cycled at 1 mA cm −2 3 mAh room temperature. approach provides useful insights into design multi‐seed concepts which, from mechanochemical perspective, various lithiophilic materials synergistically impact upon interface.

Abstract 3D porous current collectors (CCs) play a critical role in ensuring uniform lithium (Li) deposition and distributing density evenly across electrode surfaces. These attributes are essential for improving the safety stability of Li metal batteries. However, copper (Cu) ‐based CCs face notable drawbacks, such as rigid structures, insufficient pore volume, excessive mass, weak intrinsic lithiophilicity Li, which hinder their performance. To overcome these limitations, novel self‐assembly method is developed to construct highly expandable bidirectional‐gradient collector (EBG CC). This advanced design integrates Cu‐silver (Ag) ‐Cu nanowires offers high porosity, provides ample space deposition. The unique gradients conductivity within EBG CC enable nucleation, thereby stable efficient cycling Electrochemical testing half‐cell symmetric cell configurations demonstrated CC's superior rate capabilities long‐term capacity retention. Additionally, bidirectional pouch configured Li/EBG | LiFePO 4 delivered an impressive discharge 160.3 mAh g⁻¹ at 1C. results underline potential lightweight, porous, mitigating dendrite growth significantly enhancing performance anodes.

Anode-free Li-metal battery (AFLMB) is being developed as the next generation of advanced energy storage devices. However, low plating and stripping reversibility Li on Cu foil prevents its widespread application. A promising avenue for further improvement to enhance lithophilicity foils optimise their surfaces through a metal-organic framework (MOF) functional layer. excessive binder usage in current approaches obscures active plane MOF, severely limiting performance. In response this challenge, MOF polycrystalline membrane technology has been integrated into field AFLMB work. The dense seamless HKUST-1 was deposited (HKUST-1 M@Cu) via an epitaxial growth strategy. contrast traditional layers, binder-free fully exposes lithophilic sites, effectively reducing nucleation overpotential optimising deposition quality Li.
