The 3D flower-like morphology of α-Co hydroxyhalides significantly enhances their electrochemical performance compared to the hexagonal structure. By substituting chloride with iodide, the capacitive behaviour is further improved by over 40 %, thereby showcasing the critical role of halides in modulating electronic properties. This achievement makes these materials promising candidates for energy storage. More information can be found in the Research Article by V. Oestreicher, G.

Their porous structure and tunable chemical composition seem to be the main advantages for their use as electrocatalysts. Carbon-based materials derived from the MOF act as sacrificial templates with high activity, electrical conductivity and stability. In their Review (DOI: 10.1002/batt.202400402), Z.

Especially, Na4Fe3(PO4)2P2O7 (NFPP) cathode is considered to be one of the best candidates for SIBs cathode with abundant resources and long-term cycling stability. However, the impurities of NaFePO4 (NFP) and Na2FeP2O7 (NFPO) formed synchronously with NFPP which restrict the further application of NFPP. It is meaningful to clear the formation process and regulate the contents of NFP and NFPO. Therefore, NFPP cathodes with different contents of NFP and NFPO were prepared through high energy ball milling cooperated with post-heat treatment by controlling the Fe concentration in reactants. The NFPP-2.85 showed the best electrochemical performance because of the high content of NFPP and transition zone between NFPP and NFPO which fasts the Na+ transport kinetics. When employed as cathode for SIBs, the as-prepared NFPP-2.85 showed a specific capacity of 111.8 mAh g−1 at 0.1 C and maintained at 68.9 mAh g−1 even at 100 C. The retention ratio was as high as 93.6 % after 1500 cycles at 20 C, implying superior high rate-long term cycling stability. This work provides a new way for impurities regulation and the improvement of NFPP electrochemical performance.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"7 12","pages":""},"PeriodicalIF":5.1,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142869130","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}

We investigate the effect of Li atom adsorption on the electronic and structural properties of this 2D material. In both cases, the Li atom is located at the corner of the triangular-like pore (H1), but with a slight shift for the defective system. In the perfect system, the Li−C bond distances range from 2.289 Å to 2.461 Å, while in the defective case, they range from 2.237 Å to 3.184 Å. In the perfect case, the GDY−Li system becomes metallic and the Li 2 s states are stabilized. Charge transfer to the surfaces occurs near the vicinity of the Li atom. The C vacancy generates new C=C bonds similar to double bonds, enhancing the interaction with Li through strong conjugation. After Li adsorption, the sum of bond order for all the C atoms increases in both structures, from 0.4 % to 6 %. The Li storage capacity without significant restructuring is six Li atoms. When the atom concentration increases, the OCV values for Li decrease from 0.93 V to 0.23 V. For defective GDY, the specific capacity is 788 mAhg−1, which is slightly higher than for pristine case.","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":"142861162","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}
