Perovskite‐type solid‐state electrolytes exhibit great potential for the development of all‐solid‐state lithium batteries due to their high Li‐ion conductivity (approaching 10−3 S cm−1), wide potential window, and excellent thermal/chemical stability. However, the large solid–solid interfacial resistance between perovskite electrolytes and electrode materials is still a great challenge that hinders the development of high‐performance all‐solid‐state lithium batteries. In this work, a perovskite‐type Li0.34La0.51TiO3 (LLTO) membrane with vertically aligned microchannels is constructed by a phase‐inversion method. The 3D vertically aligned microchannel framework membrane enables more effective Li‐ion transport between the cathode and solid‐state electrolyte than a planar LLTO membrane. A significant decrease in the perovskite/cathode interfacial resistance, from 853 to 133 Ω cm2, is observed. It is also demonstrated that full cells utilizing LLTO with vertically aligned microchannels as the electrolyte exhibit a high specific capacity and improved rate performance.

A self-templated strategy is developed to fabricate hierarchical TiO /SnO hollow spheres coated with graphitized carbon (HTSO/GC-HSs) by combined sol-gel processes with hydrothermal treatment and calcination. The as-prepared mesoporous HTSO/GC-HSs present an approximate yolk-double-shell structure, with high specific area and small nanocrystals of TiO and SnO , and thus exhibit superior electrochemical reactivity and stability when used as anode materials for Li-ion batteries. A high reversible specific capacity of about 310 mAh g at a high current density of 5 A g can be achieved over 500 cycles indicating very good cycle stability and rate performance.

Development of high performance electrode materials for sodium-ion batteries has been given a lot of attention in recent years but challenges remain. Herein, we have successfully synthesized the first NiS/MoS 2 /C composite hollow spheres (NMSCHSs) via a facile hard template method combined with calcined sulfidation process. Owing to its unique hierarchical nanostructure with NiS nanoparticles embedded in shell wrapped with MoS 2 nanosheets, the NMSCHS-based anode electrodes exhibit superior rate capability and cycling stability, with a specific discharge capacity of 516 mAh g −1 and 98.5% retention after 60 cycles at a current density of 0.1 A g −1 and a discharge capacity of 398 mAh g −1 even at 5 A g −1 .

TiO2 is well‐known nanomaterials and mostly used as solid nanoparticles, and normal hollow spheres for photocatalysts or electrode materials. In this study, a novel self‐templated method is presented to successfully fabricate high‐surface‐area ultrathin nanosheets constructed TiO2 hollow spheres through the solvothermal treatment of the titanate–silicone composite particles combined with calcination. The uniquely structured hollow spheres exhibit excellent rate capability and good cycle stability even at a high current density of ≈10 C for the anode material of Li‐ion battery.

Nitrogen-doped microporous carbon nanofilm/MoS2 composites (NMC-nanofilm@MoS2) were synthesized by immersing MOP nanofilms in (NH4)2MoS4 methanol solution and a subsequent annealing process.

Continuous carbon hollow shells with embedded ZnO nanoparticles were synthesized from colloidal polystyrene/ZnO as templates and glucose oligomer as the carbon source followed by calcination. The resulting uniform ZnO/C hollow spheres display a relatively high reversible capacity of 994 mAh g−1 after 100 cycles at 0.1 A g−1 and 812 mAh g−1 after 200 cycles at 1 A g−1, which is superior to most reported ZnO‐based anode materials. The excellent electrochemical performance of the ZnO/C hollow spheres may arise from the following aspects: the shortened pathway of Li ions and electrolyte attributed to the unique hollow shell structures, improved electronic conductivity, firm encapsulation of ZnO nanoparticles, and high specific surface area of the products, which together facilitate the ZnO nanoparticles to undergo the alloying reaction completely.
