Sulfide all-solid-state batteries (SASSBs) with ultrahigh-nickel layered oxide cathode (LiNixCoyMn1-x-yO2, NCM, x >= 0.9) offer the potential of high energy density and safety for superior energy storage systems. However, stable cycling is difficult to realize due to adverse interfacial reactions, space charge layer (SCL), and elemental diffusion. Herein, we use a LiNbO3-Li3BO3 mixed coating of LiNbO3-Li3BO3 on a single-crystal Li[Ni0.92Co0.06Mn0.02]O2 (SC-Ni92) to enhance interfacial stability between SC-Ni92 cathode and sulfide solid electrolyte. Electrochemical performance shows that SC-Ni92@LiNbO3-Li3BO3/Li6PS5Cl/Li-In SASSBs exhibit the best electrochemical performance, including 88.4 % capacity retention at 1.50 mA cm-2 current density (1 C) for 100 cycles, and a discharge capacity of 150.1 mAh g-1 at 7.49 mA cm-2 high current density (5 C). The strategies adopted in this study provide valuable insights and guideline for the design of high-energy-density Ni-rich cathode materials for SASSBs.

3d Gaussian Splatting can create virtual models with captured real-world images using a camera mounted on a mobile robotic arm. However, the Gaussian model quality deteriorates when parts of the object that have not been previously captured are exposed in Vr interaction. This poster presents a human-in-the-loop Gaussian model enhancement method, comprising pre-training, viewpoint labeling, robotic image re-capture, and Gaussian model enhancement. By incorporating newly re-captured images, the enhanced models achieve improved image similarity metrics compared to the pre-trained ones, with minimal optimization time. This method facilitates continuous quality improvement, making Gaussian models more adaptable for Vr applications. © 2025 IEEE.

The In-Vessel retention (IVr) is an attractive strategy which could avoid the failure of reactor Pressure Vessel (rPV) and consequent phenomenon in severe accident of nuclear power plants (NPPs). Most advanced NPPs designed in China adopt the IVr measure, e.g. ACPr1000, CAP1400 and HPr1000. In this paper, the IVr designs of different advanced NPPs in China are described and compared, and relevant IVr analyses and experimental work are introduced, then several key IVr technical issues are discussed and corresponding technical positions are given. In general, IVr is proposed as an effective measure based on current analysis, also several suggestions are put forward to further improve the likelihood of IVr success. © 2021 Xi'an Jiaotong University
