Many of these oxides show interesting kinetic behavior but have poor structural stability. To overcome this limitation, an alternative material containing potassium in the interlayer space in trigonal prismatic coordination is studied here. The transition-metal layers are formed by sustainable transition elements such as iron and manganese. The solid was prepared using a sol–gel procedure that led to a product with relatively high purity, with a Pʹ3-type structure indexable in the C2/m space group of the monoclinic system. Its electrochemical behavior was studied in sodium metal half-cells. When the cell is charged up to 4.3 V, it is observed that the potassium extraction is not complete. The subsequent discharge of the cell is associated with the intercalation of sodium from the electrolyte. Thus, it is possible to incorporate a greater number of alkaline ions than those extracted in the previous charge. The residual potassium in the structure was found to be favorable to maintaining the structural integrity of the compound upon cycling. This can be explained by the beneficial effect of potassium, which would act as a structural “pillar” in the interlayer, which would reduce structural degradation during cycling.","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"3 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.20230057","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139476688","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}

To increase the overall performance of Li-O2 batteries, it is essential to increase the efficiency of oxygen electrode reactions by constructing effective electrocatalysts. As a high-efficiency catalyst for Li-O2 batteries, high entropy perovskite oxide (La0.8Sr0.2)(Mn0.2Fe0.2Cr0.2Co0.2Ni0.2)O3 (referred to as LS(MFCCN)O3) is designed and investigated in this article. The introduction of dissimilar metals in LS(MFCCN)O3 has the potential to cause lattice deformation, thereby enhancing electron transfer between transition metal ions and facilitating the formation of numerous oxygen vacancies. This feature is advantageous for the reversible production and breakdown of discharge product Li2O2. Consequently, the Li-O2 battery utilizing LS(MFCCN)O3 as a catalyst achieves an impressive discharge capacity of 17,078.2 mAh g−1 and exhibits an extended cycling life of 435 cycles. This study offers a useful method for adjusting the catalytic performance of perovskite oxides toward oxygen redox reactions in Li-O2 batteries.","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"3 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.20230053","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139415057","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}

With this in mind, Ce-doped Bi2O3 (Ce-BT) nanoflower spheres were synthesized by a facile and rapid microwave-assisted solvothermal method for HSCs anode materials. It is found that the morphology of BT could be controlled by Ce doping from stacked nanosheets to well-dispersed nanoflowers spheres and producing abundant amorphous regions, thus expediting the ion transport rate. Consequently, when the added Bi to Ce molar ratio is 40:1 (Ce-BT-40), it exhibited a specific capacity of 220 mAh g−1 at 0.5 A g−1. Additionally, when fabricating HSCs with as-prepared Ce-BT-40 and CeNiCo-LDH, an energy density of 59.1 Wh kg−1 is provided at a power density of 652 W kg−1. This work not only reveals the mechanism of the effect of Ce doping on the electrochemical properties of BTs, but also proposes a rapid synthesis method of Ce-BTs by microwave-assisted solvent method, which provides new insights for building advanced HSCs with high energy density and low cost.","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"3 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.20230052","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139374369","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}

However, their widespread commercial adoption has been inhibited by critical challenges, for example, the capacity fading from irreversible processes at electrolyte/electrode interfaces and safety concerns originating from the inhomogeneous lithium deposition. Polymer electrolytes benefiting from enhanced electrolyte/electrode contact and low interfacial impedance provide a variable solution to address these challenges and enable a high-energy and flexible battery system. Although promising, inefficient bulky ionic conductivity and poor mechanical stability confront the stable operation of polymer electrolytes in tangible batteries, which highly requires the development of innovative polymer electrolyte chemistries. Among various polymer materials, microporous polymers stand out due to their abundant porosity and customizable micropore structure, positioning them as promising candidates for next-generation electrolyte membranes. This review, therefore, summarizes recent advances in electrolyte membranes based on two new chemistries, hypercrosslinked polymers (HCPs) and porous coordination polymers (PCPs). Other microporous polymers, such as covalent organic polymers, porous organic cages, and polymers of intrinsic microporosity, are also discussed with an emphasis on their applications in LMBs. Most importantly, by reviewing the design strategies, synthesis protocols, and performance in LMBs, we gain insights into the design principles of high-performance electrolyte membranes based on HCPs and PCPs and highlight potential future research directions.","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"3 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.20230050","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139374229","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}

However, the serious side reactions and dendrites growth during the process of sodium ions deposition/stripping are the bottleneck that inhibits the further capitalization of SMBs, especially at low temperatures. Herein, a porous framework of 50 μm thickness composite gel-polymer-electrolyte (GPE) supported by polyvinylidene difluoride nanowires membrane and Na3Zr2Si2PO12 ceramic particles is proposed to tackle the issues.

Moreover, the full battery based on this GPE has an extraordinary performance at low temperatures, reaching a specific capacity of 93 and 61 mAh g−1 at 0.5 and 1 C at −20°C, respectively.
