Summary: This study comprehensively examines the feasibility of second-life batteries (SLBs) in stationary energy storage applications, considering technical and financial uncertainties. According to the optimal results, SLBs could increase energy efficiency by up to 14% with 80% capacity and under 80% depth of discharge (DOD). It has also been found that if the SLB cost is less than 57% of the fresh battery (FB) cost, the same system will reach the break-even point. The introduction of carbon tax reduced the discount payback for SLBs by at least 3 years, increased return on investment (ROI) by 5%, and improved state of health (SOH) by 13%, achieving sustainable environmental and economic results.

Summary: The adoption of electric vehicles is increasing worldwide, but the sustainability of their batteries remains a concern. The sourcing of raw materials and end-of-life management are environmental challenges. Circular strategies are needed to support the sustainability of battery placement in the transportation system. Battery recycling for a secondary supply is favorable for producers, but reuse is more environmentally attractive from a holistic lifecycle perspective. However, there are barriers to current reuse policies and practices due to cost breakdown and reliability uncertainties.

Summary: By introducing a nanofluid electrolyte with aluminum oxide additive, a protective layer is formed on the electrodeposited zinc anode, which enhances its zincophilicity and homogenizes the deposition of zinc hydroxide to prevent dendrite formation and electrode shape change. Additionally, the diffusion of zinc hydroxide from the anode surface to the bulk electrolyte is suppressed, promoting interface stabilization, improving zinc utilization rate, and inhibiting corrosion. As a result, the flexible zinc-nickel batteries assembled with aluminum oxide-nanofluid electrolyte and electrodeposited zinc anode exhibit superior energy density of 210 Wh L-1 and stable cycling for 575 hours, showing promising potential in the field of wearable and portable electronics.

Summary: To address the issues of self-corrosion and uneven deposition of zinc anode in alkaline nickel-zinc batteries, polyethylene glycol (PEG-300) was introduced as an electrolyte additive. PEG-300 can selectively adsorb on the zinc anode to form a protective layer, inhibiting the tip effect and limiting the lateral diffusion of [Zn(OH)4]2-. Moreover, the long-chain molecules of PEG suppress the diffusion of [Zn(OH)4]2- from the surface of zinc anode to the bulk electrolyte, thereby inhibiting self-corrosion. Experimental results demonstrate that the assembled Ni-Zn battery with 2% PEG additive exhibits an ultra-long cycling life and excellent performance.

Summary: Flexible zinc-air batteries (FZABs) based on poly(vinyl alcohol) (PVA) alkaline gel polymer electrolyte (GPE) have poor cycling life, mainly due to the decline of the OH- ion content in the PVA-KOH GPE. Factors such as the formation of ZnO and carbonate in the GPE, as well as its poor water retention capability, contribute to the decrease in OH- ion content. This study provides valuable theoretical guidance and reference for prolonging the cycle lifetime of FZABs using PVA-KOH GPE.

Summary: SiOx anode has attracted great attention due to its higher specific capacity and better capacity retention compared to graphite and pure Si. However, its low initial Coulombic efficiency and inadequate capacity retention limit its further application. The academia has proposed various strategies to address these challenges, but they seldom meet the industry's requirement for excellent overall performance. This review introduces and critically evaluates the modification strategies that are already or likely to be accepted by the industry. Additionally, the fundamental mechanisms of SiOx and the relationship between its structure and performance are systematically discussed.

Summary: The effects of different proportions of hydrothermal medium composition on the hydroxylation process were explored to obtain high tetragonality in tetragonal barium titanate (BT) powders. The optimal solvent condition of water:ethanol:ammonia solution of 2:2:1 resulted in a BT powder with a high tetragonality of 1.009, which increased with the particle size. The uniformity and dispersion of BT powders with particle sizes of 160, 190, 220, and 250 nm were improved by the inhibition of ethanol on the interfacial activity of BT particles (BTPs). The core-shell structure of BTPs was revealed, explaining the relationship between tetragonality and average particle size.

Summary: Zinc-nickel batteries are considered ideal for next-generation energy storage due to their high safety, low cost, and excellent rate performance. However, the limited reversibility of the zinc electrode hinders their shelf life and cycling life. By constructing a dense and uniform ZnS coating layer on the ZnO surface, the stability of the ZnO anode is improved, resulting in enhanced reversibility and reactivity. The ZnS layer also protects the active zinc and regulates ion migration, mitigating shape change and dendrites growth. This results in a zinc-nickel battery with improved storage life and cycling life, demonstrating great promise for practical applications.

Summary: By solid-phase Mg doping reaction, the performance of silicon suboxide (SiOx) as an anode material for lithium-ion batteries can be improved. Magnesium (Mg) can reduce SiO2 in SiOx to Si and form MgSiO3 or Mg2SiO4, which are mainly distributed on the surface of SiOx, suppressing lithium-ion loss and enhancing the initial Coulombic efficiency (ICE) of SiOx. However, this reaction sacrifices the capacity of SiOx. By controlling the reaction process, the phase composition, proportion, and morphology of Mg-doped SiOx can be tuned to improve its performance.

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.
