Moreover, they are widely used in the latest models of all electric vehicles (EVs) and hybrid electric vehicles (HEVs). However, to meet the demand for EVs and HEVs, notable improvements in commercially available LIBs are required. These include improving energy density, cycling life, power and rate capabilities, safety, and cost. In spite of the initial commercialization of LIBs in 1990 by Sony, current commercial LIBs still rely on graphite/carbon as the anode material, providing a theoretical capacity of approximately 372 mAh g<sup>−1</sup>. The search is on for viable alternatives to graphite with higher capacity materials, and silicon (Si) has emerged as a promising candidate with a theoretical capacity of approximately 4200 mAh g<sup>−1</sup>. However, Si anodes face several challenges, such as considerable volume expansion during the lithiation/delithiation process, which leads to significant crystallographic-related phase-induced stresses, continuous formation of a solid electrolyte interface (SEI), and cycle retention decay. The volume expansion caused by stress leads to the pulverization of Si electrodes. This results in the loss of electrical contact with the substrate or current collector, causing a significant and rapid decrease in capacity and ultimately leading to battery failure. This review explores the challenges associated with Si-based anodes, their underlying causes, and their comparative advantages over conventional anodes. Furthermore, the review discusses innovative solutions to address these challenges, such as utilizing novel binders, electrolyte additives, structural, interfacial, composite engineering techniques, and prelithiation methods. Finally, considering the material cost, the suggestion to transition entirely to using up to 100% wt. silicon for anode development is proposed, streamlining practical and commercial implementation in future LIBs.</p></div>","PeriodicalId":100957,"journal":{"name":"Next Energy","volume":"5 ","pages":"Article 100176"},"PeriodicalIF":0.0,"publicationDate":"2024-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949821X24000814/pdfft?md5=1901a2af3bbb35d3fd9f67cc97e2e535&pid=1-s2.0-S2949821X24000814-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142011256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lately, an increasing number of countries and corporations have initiated the exploration of alternative energy sources to replace fossil fuels. There is a rising interest among individuals in photovoltaic solar panels as a sustainable means of generating electricity. Photovoltaic solar systems, on the other hand, rely significantly on weather conditions. As a result, the electricity generated by photovoltaic (PV) systems is unreliable. Harnessing biogas might serve as a captivating alternative for generating electricity. The study presents a proposal for a hybrid power system that combines PV solar panels and biogas. This system regards the PV solar system as the primary system. A forecast of PV production power is calculated using advanced machine-learning techniques. Subsequently, the projected power is juxtaposed with an approximation of the necessary load. If the PV system is unable to provide the necessary power demand, it is advisable to employ a biogas system to achieve a consistent and reliable power supply. Furthermore, this method offers a forecast of the daily waste demand for a reliable electrical grid. High-capacity manufacturing during the winter season is tested using a proposed solution for calculating biogas capacity and waste amount. The study introduces mathematical equations to address the daily biomass requirements of the system and implements an automated control system to oversee operations. The utilization of the proposed equations and control flow chart methodology effectively facilitates the precise quantification of methane generated from beef manure, reducing the margin of error from 12.82% to 8.28%. Additionally, it enables prompt adjustments to optimize equipment performance.

It synthesizes research on how droughts, floods, heatwaves, hurricanes, and wildfires each initiate a chain reaction within the interconnected domains of water, energy, and carbon. Key insights include the analysis of drought impacts, like in California, where hydroelectric power's share dropped from 18% to 7%, leading to a 34%increase in emissions from natural gas plants. In Europe, flooding led to operational challenges for power plants, with a projected loss of 0.6–4.6 TWh in energy generation by 2030 due to water temperature rises. The 2023 European heatwave saw Spain's energy demand spike by 20%, driven by increased use of air conditioning, and a corresponding 15–20% rise in carbon emissions in affected countries due to greater reliance on fossil fuels. The review emphasizes the need for integrated resilience strategies, leveraging the provided quantitative data to argue for policies that address these interdependent challenges. It urges for a nuanced understanding of the WEC Nexus's dynamics to inform more effective responses to the rising tide of climate change-induced extreme weather events. Furthermore, this review expands its examination to include cases from developing countries, showcasing how their unique challenges and responses within the WEC Nexus contribute to a more comprehensive understanding of global resilience strategies against extreme weather. This review brings to the forefront the ripple effects of alterations in energy production on water resources and carbon dynamics, underscoring the critical need for a nuanced understanding and integrated approaches in managing the WEC Nexus in the face of extreme weather events.</p></div>","PeriodicalId":100957,"journal":{"name":"Next Energy","volume":"5 ","pages":"Article 100151"},"PeriodicalIF":0.0,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949821X24000565/pdfft?md5=482ba2f12206e31fedd72f7d96788ed3&pid=1-s2.0-S2949821X24000565-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141950542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
