“…Additionally, the reversible specific capacity of NLTO-NF at 0.1, 0.2, 0.5, 1.0, 2.0, 3.0, and 4.0 A g –1 reaches 265, 219, 183, 157, 135, 124, and 118 mAh g –1 , respectively (Figure c). Compared with other perovskite-type or Ti-based materials (Figure e and Table S2), − ,− the NLTO-NF anode exhibits appreciable reversible specific capacity and superior rate performance. Such admirable rate capability profits from the excellent conductive N-doped carbon skeleton and unique multichannel structure, which highly promote the electron transportation and migration of Li + .…”

“…In recent years, some perovskite-type oxides ABO 3 were found to act as the insertion-type anodes of LIBs that can achieve admirable performance owing to their abundant insertion sites in the lattice and the excellent tolerance of the framework structure. − These perovskite oxides are composed of a [BO 6 ] octahedral framework (B = transition metal) stabilized by rare-earth and alkali (Li) atoms in A sites. The robust framework possesses abundant sites, which can allow the insertion of various ions and keep structural stability .…”

High-capacity" graphite and "zero-strain" spinel Li 4 Ti 5 O 12 (LTO) occupy the majority market of anode materials for Li + storage in commercial applications. Nevertheless, their intrinsic drawbacks including the unsafe potential of graphite and unsatisfactory capacity of LTO limit the further development of lithium-ion batteries (LIBs), which is unable to satisfy the ever-increasing demands. Here, a novel Na 0.35 La 0.55 TiO 3 perovskite embedded in multichannel carbon fibers (NLTO-NF) is rationally designed and synthesized through an electrospinning method. It not only has the advantages of a respectable specific capacity of 265 mAh g −1 at 0.1 A g −1 and superb rate capability, but it also possesses the zero-strain characteristic. Impressively, an ultralong cycling life with 96.3% capacity retention after 9000 cycles at 2 A g −1 is achieved in the half cell, and 90.3% of capacity retention ratio is obtained after even 2500 cycles at 1 A g −1 in the coupled LiFePO 4 /NLTO-NF full cell. This study introduces a new member with excellent performance to the zero-strain materials family for next-generation LIBs.

Double perovskite alloys are of significant interest owing to their intriguing magnetic properties and potential practical applications. In this study, we provided a detailed report on the structural, electrical and magnetic features of the double perovskite LaCaMnFeO6, prepared via the conventional solid-state reaction technique. Neutron diffraction analysis showed that the sample is single-phase adopting the Pnma orthorhombic structure with random distribution of La3+/Ca2+ and Mn4+/Fe3+ ions on A- and B-sites, respectively. A long-range G-type antiferromagnetic order was formed below TN = 250 K. Magnetic measurements unveiled a cluster glassy behavior at low temperatures with a complex distribution of cluster magnetic anisotropy energy. Ferromagnetic clusters consisting of two Mn4+ and one Fe3+ were found to exist in the paramagnetic phase. The complex magnetic properties of LaCaMnFeO6 are attributed to the cation disorder effect combined with the competition between magnetic interactions. Unusual electrical behavior with a large positive magnetoresistive effect was observed and correlated to magnetic phase transitions.

“…Current lithium-ion batteries (LIBs) based on graphite negative electrodes already could not meet the growing energy demand for poor safety and limited energy density [1][2][3][4][5] . Solid state electrolytes (SSEs) strengthen the battery safety essentially by replacing flammable organic liquid electrolytes and polymer separator [6][7][8][9][10] .…”

Garnet oxide is one of the most promising solid electrolytes for solid-state lithium metal batteries. However, the traditional interface modification layers cannot completely block electron migrating from the current collector to the interior of the solid-state electrolyte, which promotes the penetration of lithium dendrites. In this work, a highly electron-blocking interlayer composed of potassium fluoride (KF) is deposited on garnet oxide Li6.4La3Zr1.4Ta0.6O12 (LLZTO). After reacting with melted lithium metal, KF in-situ transforms to KF/LiF interlayer, which can block the electron leakage and inhibit lithium dendrite growth. The Li symmetric cells using the interlayer show a long cycle life of ~3000 hours at 0.2 mA cm−2 and over 350 hours at 0.5 mA cm−2 respectively. Moreover, an ionic liquid of LiTFSI in C4mim-TFSI is screened to wet the LLZTO|LiNi0.8Co0.1Mn0.1O2 (NCM) positive electrode interfaces. The Li|KF-LLZTO | NCM cells present a specific capacity of 109.3 mAh g−1, long lifespan of 3500 cycles and capacity retention of 72.5% at 25 °C and 2 C (380 mA g−1) with an average coulombic efficiency of 99.99%. This work provides a simple and integrated strategy on high-performance quasi-solid-state lithium metal batteries.
