However, under industrial conditions using high-density electrodes (>1.6 g cc–1, low electrode porosity), the electrode expansion becomes more severe, which engenders the decrease in energy density and safety issues. Carbon nanotubes (CNTs) have emerged as promising additives due to their outstanding electrical conductivity and mechanical strength. Despite their potential, the chemo-mechanical and electrochemical roles of CNTs in silicon-based anodes are not fully understood. Herein, we identify the mechanisms by which CNTs enhance silicon-based anodes with constructive comparison of commercial conductive agents. Our results show that CNTs alleviate strain-induced interfacial reactions and control the growth of the solid electrolyte interphase (SEI) layer during cycling. CNTs provide mechanical reinforcement, reducing particle-level cracking and enhancing electron pathways, which lowers surface tension and decelerates crack propagation. This significantly diminishes electrode pulverization and swelling. As a result, we observe a stable cycling stability (Cycle life: 94.6% for 100 cycles) of silicon-graphite composite (SGC) in 1 Ah pouch-type full cell. Remarkably, the SGC blended with graphite showed better electrochemical performance at low temperature cycling, fast-charging cycling and rate capability compared to the conventional graphite.","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"147 1","pages":""},"PeriodicalIF":20.4,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142887126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the key issues remain unsolved including the shuttling of polyiodides in the I2 cathode and the severe corrosion and dendrite growth in the zinc anode. This work propose a novel water reducer-based gel electrolyte, PC-PVA/Zn(CF3SO3)2, to concurrently handle with Zn anode and I2 cathode. Specifically, the hydrogen evolution corrosion for the Zn anode is effectively inhibited by forming hydrogen bonds to lock free H2O molecules and the dendrite growth of the Zn anode could be hindered by adjusting the electric filed to realize the homogenous Zn2+ deposition. Simultaneously, the abundant polar oxygen-containing group in PC-PVA gel can capture polyiodide and mitigate the “shuttle effect”, thereby enhancing the I2/I− redox kinetics. This hydrogel electrolyte with excellent mechanical properties also gives rise to the electrode's high stability. As a result, such a PC-PVA/Zn(CF3SO3)2 electrolyte enables Zn anode with an excellent lifespan over 4000 cycles and at 1 mA cm−2, 1 mAh cm−2, and the average coulombic efficiency could attain 99.4%. And the resulting Zn||I2 full cells also demonstrate excellent performances, which the reversible capacity could maintain at 155.2 mAh g−1 after 5000 cycles at 1 A g−1, and the capacity decay rate is only 0.0015% per cycle. This cost-effective and readily available gel electrolyte provides a viable strategy for commercializing Zn-I2 batteries.","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"8 1","pages":""},"PeriodicalIF":20.4,"publicationDate":"2024-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142884669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, challenges such as phase separation arising from different expansion coefficients among phases under high voltage or during prolonged cycling have been a concern.

The introduced stabilized spinel-bridged phase can create a structural confinement between the O3 and P2 phases and realize interface reconstructing simultaneously by target-element optimization. Based on the experimental and computational results, the multiphase riveting-structured O3/spinel/P2 triphasic structure provides a structural constraint and alleviates the internal stress, which can suppress detrimental irreversible phase changes to enhance the structural reversibility and stability.

One highly effective method by biphasic hybridization (such as P2/O3) is typically used to enhance reversible capacity and cycling stability.

Here, an insight into thermodynamics origin is unveiled within P2/O3 Na2/3Li1/18Ni5/18Mn5/18Ti5/18Fe2/18O2 (NLNMTF) biphasic layered cathodes, in which thermodynamics and crystal structure are designed to improve reversible capacity and cycling performance. The NLNMTF3 cathode optimized upon 15 h of calcination, which is the most thermodynamically favorable as revealed by density functional theory calculations, exhibits both the maximum O3-phase content (70.27%) and the enlarged Na interlayer distance. Significantly, the NLNMTF3 cathode delivers a high reversible capacity of 97.8 mAh g−1 at 0.1C, superior rate capability of 78.8 mAh g−1 at 5C, and excellent capacity retention of 85.5% after 500 cycles at 1C.

A step function is used to distinguish between the ‘active’ and ‘dead’ states of localized lithium metal. The galvanostatic conditions are described using Ohm's law. The relationship between voltage, current density, and internal resistance is also established. High-throughput (HTP) PF simulations of Li-Li symmetric cells show the effects of current density and ion diffusion coefficient on the growth of lithium dendrites. The morphological changes are quantitatively characterized by introducing the perimeter-to-area ratio. It is found that higher current densities and lower diffusion coefficients accelerate dead lithium accumulation, hindering ion transport and leading to an increase in potential. The accumulation of dead lithium directly causes battery capacity degradation. Finally, by combining HTP-PF simulations with machine learning, the study establishes the relationship between battery parameters (e.g., current density, diffution coefficient, and number of cycles) and performance (e.g., battery life and Coulombic efficiency (CE)). This approach aims to address the issue of high computational cost associated with applying PF methods to predict battery performance under cycling conditions. It is expected that combining HTP-PF simulation with machine learning, along with experimental validation in the future, will provide new ideas for accelerating the development of lithium batteries.","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"33 1","pages":""},"PeriodicalIF":20.4,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142870080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, their high oxidation stability allows the use of high-voltage cathodes. However, the practical application of garnet solid electrolytes faces severe challenges: 1) difficulty in sintering thin and large-area garnet solid electrolytes, 2) large interfacial resistance between garnet electrolytes and electrode materials, and 3) Li dendrite growth. This review primarily summarizes recent advances in garnet-type solid electrolytes and emphasizes the key challenges hindering their practical application in Li-metal batteries.

Supercapacitors have the ability to power wearable electronics systems because of their rapid storage capabilities, short discharge times, wearability and flexibility, and superior cyclic stability. Supercapacitor charging can be achieved by integrating mechanical energy harvesters based on piezoelectric and triboelectric effects to develop self-charging power systems (SCPSs). However, triboelectric nanogenerators (TENGs) are preferred over piezoelectric nanogenerators (PENGs) as they are easy to design in different device modes, and offer mechanical energy extraction from body movements, high electrical performance and a wide choice of device materials. This paper comprehensively explores recent emerging trends in flexible supercapacitors integrated with TENGs to develop SCPSs for multifunctional electronics applications. It delves into the operational principles of supercapacitors and TENGs, material selection, the integration of various supercapacitor configurations with TENGs for diverse application perspectives, and the timeline on the development of SCPSs.
