When applied to NCM811||Li battery system, PDOL electrolyte helps optimize the contact and interface stability between electrolyte and electrodes. This study explores the effects of PDOL with PE separators coated with Li1.3Al0.3Ti1.7(PO4)3(LATP) on the performance of NCM811||Li batteries. 2,2,2-trifluoroethyl phosphite (DETFPi), was mixed with DOL at a 1 : 35 mass ratio. Then, LiBF4 was used to initiate in-situ polymerization and thereby obtained DETFPi-PDOL electrolyte after 24 h at room temperature. The composite electrolyte exhibits enhanced ion conductivity (1.59×10−4 S cm−1), high lithium ion transference number (0.78), wide electrochemical stability window (4.53 V), and high critical current density (2.2 mA cm−2). Li||PDOL@LATP||Li battery shows extremely low overpotential (35 mV) after a constant current stable cycle of 500 h at 1.0 mA cm−2. After 500 cycles at 1 C, the remaining capacity is 153.9 mAh g−1 with a capacity retention of 82.1 % in NCM811||PDOL@LATP||Li batteries. This indicates that the LATP coating on the surface of the PE separator plays an important role in optimizing the performance of DETFPI-PDOL electrolyte batteries. LATP and DETFPI-PDOL are effective in improving the cycling stability, rate performance, and interface state of NCM811 batteries.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"8 3","pages":""},"PeriodicalIF":5.1,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143632662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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 challenge remains to develop a simple, scalable fabrication method that achieves both high energy and power densities. In this study, we present a refined approach to fabricating MSCs with 3D interconnected graphene/carbon nanotube (CNT) composite electrodes. Our method combines flash lamp annealing (FLA) and laser ablation, where FLA converts graphene oxide (GO) and CNT composite films into 3D-structured graphene/CNT electrodes, and laser ablation precisely patterns them into interdigitated designs. This dual-process technique produces MSCs with exceptional electrochemical performance, including an impressive areal capacitance of 26.11 mF/cm2 and a volumetric capacitance of 31.88 F/cm3. These devices also achieve energy densities of 3.72 μWh/cm2 and 4.43 mWh/cm3, maintaining 97 % of their initial capacitance under extreme bending, demonstrating outstanding mechanical flexibility and durability. Furthermore, the scalability of this method was validated by configuring MSCs in series and parallel, achieving enhanced voltage and current outputs without additional interconnections. Overall, the integration of FLA and laser ablation holds significant promise for advancing the performance and scalability of micro-sized energy storage devices, addressing the growing need for efficient, flexible, and high-capacity micro-power sources.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"7 12","pages":""},"PeriodicalIF":5.1,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142861161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the preparation of Li1+xMn2−xO4 faces significant challenges due to the difficulty in achieving a balance between well-crystallized phases and stoichiometric chemistry. Moreover, the synthesis process is highly sensitive to calcination temperature and time, making it susceptible to phase transformations. Therefore, the rational selection of precursors and corresponding calcination procedures is absolutely essential. Herein, we make full use of the nature of metal-organic frameworks (MOFs) to achieve phase-controlled synthesis of Li(Li0.17Mn0.83)2O4 (LMO−F) spinel cathodes in 8 minutes at 500 °C.

However, the reductive decomposition mechanism of FEC and VC has not yet been fully clarified. For this purpose, we investigate the electrolyte decomposition in LiNi0.6Co0.2Mn0.2O2 (NCM622)/silicon-graphite pouch cells containing either 1 M LiPF6 in FEC:dimethyl carbonate (DMC) or 1 M LiPF6 in VC:DMC using high-performance liquid chromatography, gas chromatography, X-ray photoelectron spectroscopy, and inductively coupled plasma optical emission spectrometry. Based on the molar consumptions of FEC and VC, and the cumulative irreversible capacities, we show that three electrons are consumed for every reduced FEC molecule, and that one electron is consumed for every reduced VC molecule. Based on the results, reactions of the FEC reduction are proposed yielding LiF, Li2CO3, Li2C2O4, HCO2Li, and a PEO-type polymer. Furthermore, the reaction of the VC reduction is proposed yielding lithium-containing, polymerized VC. During formation, the capacity loss of the cells is induced by lithium trapping in LixSiy/LixSiOy under the SEI and by lithium trapping in the SEI. During subsequent cycling, only lithium trapping in the SEI triggers the capacity loss.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"8 4","pages":""},"PeriodicalIF":5.1,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/batt.202400499","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143827069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these batteries always suffer from inferior electrochemical performance, because of dendrite growth and corrosion/passivation of the anodes. Herein, a copper iodide-polyvinylpyrrolidone (CuI-PVP) composite layer is proposed to suppress the parasitic reactions and protect the Zn anodes. In this layer, the CuI can spontaneously react with metallic Zn and convert into Cu and Cu5Zn8 (2CuI+Zn→2Cu+ZnI2; 5Cu+8Zn→Cu5Zn8). The highly zincophilic Cu and Cu5Zn8, as heterogeneous seeds, can guide the uniform Zn nucleation and deposition, while alleviating corrosion of the Zn anodes. At the same time, the iodide species releasing from the composite layer can be oxidized and deposited on the cathodes, contributing additional capacity. As a result, the symmetric cell prepared with the CuI-PVP@Zn anodes demonstrates a long cycling lifetime of 1400 hours at 1 mA cm−2 and 1 mAh cm−2. Under an even higher current density of 5 mA cm−2, the CuI-PVP@Zn cell can still stably work for more than 660 hours. The practical application of this CuI-PVP@Zn electrode has been further demonstrated in Zn-I2 full batteries, which achieve 60 % higher specific capacity than the untreated ones (251.4 vs. 157.1 mAh g−1 after 2800 cycles).","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"8 2","pages":""},"PeriodicalIF":5.1,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143431649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
