Summary: With the rapid development of technology, improving the utilization and conversion rate of sustainable energy has become crucial for ecological and sustainable development. However, the limited capacity and poor electrochemical property of current electrode materials hinder this progress. In this study, a lithium metal composite anode was developed through an excessive alloying process, effectively solving the issues of dendrite formation and poor electrochemical stability. The results showed that the lithium metal deposition on silver and silicon electrodes significantly enhanced coulombic efficiency and electrochemical stability, with the silver-lithium composite electrodes exhibiting twice the cycling capability of bare Cu electrodes. This new anode structure and excessive alloying process provide a promising approach for extending the application of commercial anodes.

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: 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.
