Summary: A delayed nucleation strategy is proposed to improve the performance of Zn anodes in aqueous Zn-ion batteries. Through a liquid metal (LM) interlayer, the reduction and deposition of Zn are temporally and spatially separated, achieving fast Zn redox kinetics and dendrite-free Zn (002) deposition. The flexible anode (Zn@LM-AgT) demonstrates stabilized Zn plating/stripping cycling over 700 hours with reduced overpotential, and when coupled with a vanadium-based cathode, the full cell exhibits six times higher remaining capacity after 1000 cycles compared to the reference cell. The delayed nucleation mechanism provides a novel approach to high-performance metallic anodes.

Summary: Aqueous rechargeable Zn-ion batteries (ARZIBs) have gained attention for their safety, high energy density, and environmental friendliness. However, dendrite formation and corrosive reactions on the Zn anode surface have posed challenges. In this study, Ga3+-doped NaV2(PO4)(3) with Na superionic conductor (NASICON) structure was used as an artificial layer to stabilize the Zn anode. The optimal NVP-Ga(0.5) layer effectively homogenized ion flux and promoted uniform deposition of zinc, inhibiting dendrite growth and parasitic reactions. The resulting batteries showed stable operation and high discharge capacity.

Summary: Rechargeable aqueous zinc metal batteries have received great attention due to their safety and low cost. However, the growth of zinc dendrites in aqueous electrolytes severely limits the lifespan of these batteries. In this study, a strategy was proposed to enhance the activity of zinc-alloying sites by introducing a small amount of polar organic additive in the electrolyte, forming a molecular crowding layer to prevent parasitic water reduction during zinc deposition. This multifunctional interfacial structure allows stable cycling of the zinc anode and can potentially improve the performance of other aqueous metal batteries.

Summary: In this study, core-shell structured composite matrixes were used to achieve nearly fully reversible cycling of sulfur cathodes for Na-S batteries. The bidirectional tandem electrocatalysis enabled successive reversible conversion of both long- and short-chain polysulfides, while Fe2O3 and redox-active Fe(CN)(6)(4-)-doped polypyrrole shell facilitated specific conversions. The electrochemically reactive Na2S could be readily charged back to sulfur, and stable cycling of a Na-S pouch cell with high reversible capacity was demonstrated.

The formation mechanism of the pore structure evolution of LPC was elucidated, and the obtained porous carbons showed excellent electrochemical performances. This combined sustainable production process has the potential to be developed as a practical method for producing calcium chloride and porous carbons.

Summary: This study reports the preparation of hard carbons with different pore structures by carbonizing different lignin precursors, and investigates the relationship between their microstructures and sodium-ion storage performance. Hard carbon prepared from corn cob lignin shows the highest closed pore volume, resulting in the highest plateau capacity. The formation of closed pores is attributed to the transformation of micropores at high carbonization temperatures. The study proposes a method for calculating the closed pore volume and finds a positive correlation between plateau capacity and closed pore volume.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
