Article Abstract

This study comprehensively investigates the phase evolution of silver-carbon composite (Ag/C) layers in anode-less batteries with both liquid and solid electrolytes. The results of X-ray diffraction and cross-sectional electron microscopy analyses reveal that the alloying reaction of Ag and Li is more homogeneous in solid-electrolyte-based cells compared to liquid-electrolyte-based cells. This homogeneity is attributed to diffusional Coble creep across the heterogeneous interfaces of Ag/C layers and solid electrolytes.

Alloy anodes with high specific capacity are extensively utilized in all-solid-state batteries (ASSBs). However, they are challenged by interfacial kinetic and mechanical issues. Real-time investigation of interfacial failure mechanisms at the nanoscale is crucial for optimizing the alloy anodes.

Anode-less lithium-sulfur (Li-S) batteries offer a promising route to high energy density and cost-effective energy storage, yet suffer from unstable Li deposition and polysulfide crossover at the current collector interface. Here, we introduce a hybrid interfacial modulation layer (HIML) designed to simultaneously regulate dendrite-free Li deposition behavior and block polysulfide migration. The HIML consists of lithiophilic Au nano seeds coated with a porous ionic-selective overlayer, enabling guided, uniform Li nucleation and selective Li transport.

Anode-less batteries have gained due attention, considering the easy industrial and safer processes involved. The initial absence of an anode ideally improves the gravimetric and volumetric capacity in a battery, and the assembly process is made easier with no handling of reactive metals. Sacrificial salts, on the other hand, have been shown to be feasible in general for batteries and supercapacitors as a solid electrolyte interphase (SEI) forming agent and supplying additional Li or Na to compensate for that spent in the building of SEI.

Anode-free batteries promise high energy density but suffer from dendrites, dead sodium, and cathode Na depletion that slow ion diffusion and charge transfer. We introduce the facile chemical pre-sodiation of Cu current collectors to form a NaSn@Cu coating, which enhances Na affinity, supports uniform nucleation, and suppresses dendrites. XRD confirms improved Na diffusion in NaNiMnO, yielding markedly enhanced reversible capacity and cyclability for anode-less sodium-metal batteries.

Anode-less Zn metal batteries (ALZMBs) enhance energy density but require ultrahigh Coulombic efficiency for stability, which is hindered by side reactions and dendrite growth. A uniform Zn stripping process is essential for improving Coulombic efficiency, but the impact of separator design on Zn stripping remains unexplored. Herein, we propose a novel strategy to achieve the high reversibility of Zn plating and stripping by modifying the glass fiber (GF) separator with hydrated titanic acid (HTO), forming an HTO@GF separator.
