Improving the long-term cycling stability and energy density of all-solid-state lithium (Li)-metal batteries (ASSLMBs) at room temperature is a severe challenge because notorious solid-solid interfacial contact loss sluggish ion transport. Solid electrolytes are generally studied as two-dimensional (2D) structures with planar interfaces, showing limited further resulting in unstable Li/electrolyte cathode/electrolyte interfaces. Herein, three-dimensional (3D) architecturally designed composite solid developed independently controlled structural factors using 3D printing processing post-curing treatment. Multiple-type electrolyte films vertical-aligned micro-pillar (p-3DSE) spiral (s-3DSE) rationally developed, which can be employed for both Li metal anode cathode terms accelerating

Although composite solid-state electrolytes (CSEs) are considered promising ionic conductors for high-energy lithium metal batteries, their unsatisfactory conductivity, low mechanical strength, poor thermal stability, and narrow voltage window limit practical applications. We have prepared a new superionic conductor (Li-HA-F) with an ultralong nanofiber structure ultrahigh room-temperature conductivity (12.6 mS cm–1). When it is directly coupled typical poly(ethylene oxide)-based solid electrolyte, the Li-HA-F nanofibers endow resulting CSE high (4.0 × 10–4 S cm–1 at 30 °C), large Li+ transference number (0.66), wide (5.2 V). Detailed experiments theoretical calculations reveal that supplies continuous dual-conductive pathways results in stable LiF-rich interfaces, leading to its excellent performance. Moreover, nanofiber-reinforced exhibits good heat/flame resistance flexibility, breaking strength (9.66 MPa). As result, Li/Li half cells fabricated exhibit stability over 2000 h critical current density of 1.4 mA cm–2. Furthermore, LiFePO4/Li-HA-F CSE/Li LiNi0.8Co0.1Mn0.1O2/Li-HA-F batteries deliver reversible capacities temperature range cycling
