NASICON‐type Li1.3Al0.3Ti1.7(PO4)3 (LATP) is one of the most promising solid‐state electrolytes (SSEs) to achieve high‐energy‐density solid‐state batteries (SSBs) due to its high ionic conductivity, high‐voltage stability, and low cost. However, its practical application is constrained by inadequate interfacial compatibility with cathode materials and significant incompatibility with lithium metal. In this work, a cost‐effective interface welding approach is reported, utilizing an innovative thermal pulse sintering (TPS) to fabricate LATP‐based solid‐state batteries. Initially, the rapid thermal pulses enhance the ionic conductivity of LATP SSE by inducing selective growth of LATP nanowires, effectively occupying interparticle voids. Additionally, this process results in the formation of a dense layer (GCM) comprising graphene oxide, carbon nanotubes, and MXene with a controlled Li+ transport pathway, facilitating lithium stripping and plating processes. Moreover, these thermal pulses facilitate the interfacial fusion between LATP and cathode materials, while avoiding undesired phase diffusion. As a result, SSBs with a LiCoO2 cathode deliver favorable cycle stability at 4.6 V, marking significant progress. This facile interface welding strategy represents a substantial step toward high‐energy‐density SSB development.

“…Traditional electrothermal materials such as metal alloys and ceramics have high thermal stability, but their complex manufacturing processes, stiffness, and high-quality density limit their mass production of flexible electrothermal films. − Carbon-based materials, such as carbon nanotubes, , carbon black, , and graphene materials, − have become the best choice for flexible electrothermal films due to their low-quality density, high thermal conductivity, and high-temperature resistance. Among them, graphene material, due to its lightweight, excellent conductivity, mechanical properties, and high electrical-thermal conversion efficiency, has become one of the best choices for electrothermal materials. − A lot of work has been done on the properties of graphene-based electrothermal films.

Flexible electrothermal films are crucial for protecting equipment and systems in cold weather, such as ice blockages in natural gas pipelines and icing on aircraft wings. Therefore, a flexible electric heater is one of the essential devices in industrial operations. One of the main challenges is to develop flexible electrothermal films with low operating voltage, high steady-state temperature, and good mechanical stability. In this study, a flexible electrothermal film based on graphene-patterned structures was manufactured by combining the laser induction method and the transfer printing process. The grid structure design provides accurate real-time monitoring for the application of electrothermal films and shows potential in solving problems related to deicing and clearing ice blockages in pipelines. The flexible electrothermal film can reach a high heating temperature of 165 °C at 15 V and exhibits sufficient heating stability. By employing a simple and efficient method to create a flexible, high-performance electrothermal film, we provide a reliable solution for deicing and monitoring applications.

To inhibit the negative influence of impact on ablation performance of HfC coating reinforced by SiC nanowires (SiCnws/HfC coatings), BN interphases were fabricated and introduced into SiCnws/HfC coatings by chemical vapor deposition. The effect on BN interphase thickness upon SiCnws@BN/HfC coatings performance under impact‐ablation environment was investigated. The interphase thickness was adjusted by changing the deposition time of BN. Impact and ablation tests were carried out by drop hammer and oxyacetylene ablation devices. Among the prepared coatings, the one with 150±20 nm thickness interphase possessed a good performance under impact test, of which the crack propagation path exhibited a significant deflection. After ablation, the coating could still maintain intact surface, because the interphase thickness of 150±20 nm was appropriate to ensure the toughness of the coating and to avoid the porous structure formation.This article is protected by copyright.
