However, PEMWE still faces several critical challenges, particularly with respect to the oxygen evolution reaction (OER) at the anode. Highly active, corrosion-resistant electrocatalytic materials are required for the acidic OER owing to its sluggish kinetics involving four-electron transfer under harsh anodic potentials. To date, IrO2- or RuO2-based noble metal electrocatalysts have been employed as commercial acidic OER electrocatalysts for PEMWE. However, they remain inadequate in terms of satisfying the industrial activity/stability-related requirements. Above all, the two noble metals are too rare and expensive, which significantly inhibits widespread commercialization of PEMWE. Therefore, low-cost, highly active, and highly stable OER electrocatalysts that can operate in acidic media must be urgently developed. This review paper presents various state-of-the-art strategies employed to address the aforementioned issues by classifying them according to objectives such as improving activity, enhancing stability, and reducing cost. Then, finally, we summarize major tasks and strategies to overcome them and put forward a few issues in this field.","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"2 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.20230017","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50139675","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}

The U.S. Advanced Battery Consortium has set a goal of fast charging, which requires charging 80% of the battery's state of charge within 15 min. However, the polarization effects under fast-charging conditions can lead to electrode structure degradation, electrolyte side reactions, lithium plating, and temperature rise, which are highly linked to the thermodynamic and kinetic properties of electrolytes. The conventional nonaqueous electrolytes used in LIBs consist of carbonate and cannot support fast-charging without compromising performance and lifespan. This review outlines the challenges of fast-charging LIBs and the requirements of electrolytes suitable for fast-charging. Additionally, recent developments in fast-charging electrolytes from four key perspectives: electrolyte additives, low-viscosity co-solvents, high concentration or localized high-concentration electrolytes, and advanced electrolytes are summarized. Furthermore, this review provides insights for the design of fast-charging electrolytes based on the mechanism of charging process and offers an overview of the current state and future direction of the field.","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"2 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.20230018","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50125736","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}

EG exhibits high electrical conductivity because of the sp2 bonding on the two-dimensional plane; this conductivity provides a stable electrical pathway and promotes electron transfer in the anode. Furthermore, the small number of graphene layers in EG provide excellent mechanical properties (elastic modulus, tensile strength), which suppresses the volume expansion of the anode during lithiation; therefore, EG-based anode exhibits high capacity retention and charge/discharge cycle stability. The EG with a large specific surface area improves energy density by decreasing the amount of the additive by more than 70% compared to conventional conductive additives and by simultaneously increasing the amount of the active material. The capacity of the electrode with 3.0 wt% EG reaches 376 mAh/g even after 200 cycles at 0.2 C and 99% of its initial reversible capacity. The rate performance of the electrode with 3.0 wt% EG was about 370 mAh/g at 5.0 C. These results confirm that EG can be used as a conductive additive to overcome the limitations of existing commercial conductive agents.","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"2 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.20230012","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50122456","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 uncontrollable nucleation for SbO2− and promiscuous water-induced side reactions severely degrade the reversibility of Sb anode. Herein, the carbon-anchored Sb nanoparticles are constructed to induce uniform Sb plating/stripping for high-performance AABs. The experimental results reveal that the enhanced interaction between carbon and antimony as well as defective carbon can significantly improve the electrical conductivity and decrease the Sb nucleation overpotential. Accordingly, the as-prepared Sb anode enables preferential plating of Sb rather than parasitic side reactions. As a result, the cycle life of A-Sb/CF is sustained over 500 cycles at 10 mA cm−2/2 mAh cm−2. Even at the high capacity of 4 mAh cm−2, this anode can cycle stably for 225 cycles, which is significantly better than the Sb/CF counterpart. Furthermore, the assembled Ni3S2@Ni(OH)2//A-Sb/CF full battery demonstrates a high capacity of 2.17 mAh cm−2 and a stable cycle life of over 500 cycles.","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"2 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.20230016","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50131440","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}

In this work, a systematic study was conducted to analyze the effect of varying temperatures (−10°C, 0°C, 25°C, and 40°C) on the sealed lead acid. Enersys® Cyclon (2 V, 5 Ah) cells were cycled at C/10 rate using a battery testing system. Environmental aging results in shorter cycle life due to the degradation of electrode and grid materials at higher temperatures (25°C and 40°C), while at lower temperatures (−10°C and 0°C), negligible degradation was observed due to slower kinetics and reduced available capacity.

Although attractive, it is still a great challenge to fulfill their capacity utilization with high cycling performance. Herein, a nanoemulsion-directed method has been developed to control the spherical arrangement of ZnS@C units with both penetrating macropores from the center to the surface and inner mesopores distributed among the bulks. With respect to ion diffusion, the penetrating macropores could serve as the built-in ion-buffer reservoirs to keep a steady flow of electrolyte, while the inner mesopores facilitate the ion diffusion across the whole bulks. In terms of stability, the radical porous structure could work as self-supported vertical bones to accommodate the volume change from both lateral and vertical sides. Besides, the localized carbon distributed among the ZnS nanoparticles not only acts as binding agents to join the numerous ZnS nanoparticles but also endows the radical bones with effective electron transmission capability. As a proof of concept, such hydrangea-like ZnS@C nanospheres deliver sodium storage performance with high-rate and long-cycling capability. This nanoemulsion-directed approach is anticipated for other TMSs with penetrating pores for post-lithium-ion batteries applications.","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"2 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.20230001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50117741","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}
