Summary: Economical composite materials, such as PA66GF35, are increasingly used in the automotive industry due to their good mechanical characteristics, low density, low production cost, and high availability. However, the injection molding process used to produce these materials introduces anisotropic mechanical behavior. As a result, research has focused on the vibrating properties and comparison of vibration modes and mechanical properties. This is particularly important for automotive components affected by noise problems.

Summary: In this paper, we solve the urgent problem of constructing a recycling network for decommissioned electric vehicle batteries and clarify the responsible recycling entities. By considering costs and profits, we optimize the network and predict the future quantity of decommissioned batteries using a fuzzy-based model. Our results show that as the number of batteries grows, third-party revenues will increase significantly while facility utilization rates decrease.

Summary: As the market share of battery electric vehicles (BEVs) grows, understanding the noise, vibration, and harshness (NVH) phenomenon inside BEVs becomes crucial. Unlike conventional vehicles, BEVs lack traditional noise sources like internal combustion engines, requiring more research on previously ignored noise behaviors.

Summary: There is limited knowledge on the potential impacts of electric vehicle (EV) deployment in developing countries to date. Through a model analysis for India, it is projected that the sale of two-wheeler EVs will peak in 2030 at around 20 million units while the sale of four-wheeler EVs will steadily increase to 10 million units in 2050. It is imperative to create a safe environment for workers and surrounding communities, an extended producer responsibility (EPR) system and a national mechanism to track waste crimes related to batteries in the future.

Summary: This paper presents an optimal, multi-objective battery state-of-health (SOH) sensitive off-line HEV control approach based on dynamic programming, which is experimentally validated for prediction capability of battery lifetime. By improving the battery ageing model accuracy, the approach allows for downsizing the battery pack by 35% without impacting battery lifetime and with just a 1.1% increase in fuel consumption. Adopting this control approach could lead to significant cost, weight, and CO2 emissions reductions in battery packs for HEVs.

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: An efficient phase inversion-impregnation approach is developed to fabricate BaO-decorated Ni8 mol% YSZ anode-supported tubular solid oxide fuel cells (SOFCs) with anti-coking properties. BaO nanoislands are successfully introduced inside the Ni-YSZ anode, leading to higher peak power densities and improved stability in methane fuel. Density functional theory calculations suggest that the loading of BaO nanoislands facilitates carbon elimination by capturing and dissociating H2O molecules to generate OH.

Summary: Li-CO2 batteries, which utilize CO2 and have a high energy density, are hindered in practical applications due to slow kinetics and safety hazards. This study introduces a stable and highly conductive ceramic-based solid electrolyte and a metal-organic framework catalyst to improve the safety and performance of Li-CO2 batteries. The optimized Li-CO2 cell shows outstanding specific capacity and cycle life, and the post-cycling analysis reveals the degradation mechanism of the electrodes. First-principles calculations based on density functional theory are also performed to understand the interactions between the catalyst and the host electrode. This research demonstrates the potential of MOF cathode catalyst for stable operation in Li-CO2 batteries.

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.
