Abstract The adequate potassium resource on the earth has driven researchers to explore new‐concept potassium‐ion batteries (KIBs) with high energy density. Graphite is a common anode for KIBs; however, main challenge faced by KIBs that K ions have larger size than Li and Na ions, hindering intercalation of into electrodes thus leading poor rate performance, low capacity, cycle stability during potassiation depotassiation process. Herein, an amorphous ordered mesoporous carbon (OMC) reported...

With its inherent zig-zag layered structure and open framework, Na2Ti3O7 (NTO) is a promising anode material for potassium-ion batteries (KIBs). However, poor electronic conductivity caused by large band gap (∼3.7 eV) usually leads to low-performance KIBs. In this work, we synthesize the fluff-like hydrogenated (HNTO) nanowires grown on N-doped carbon sponge (CS) as binder-free current-collector-free flexible KIBs (denoted HNTO/CS). High-resolution X-ray photoelectron spectroscopy (XPS)...

Neural radiance fields (NeRF) achieve impressive performance in novel view synthesis when trained on only single sequence data. However, leveraging multiple sequences captured by different cameras at times is essential for better reconstruction performance. Multi-sequence data takes two main challenges: appearance variation due to lighting conditions and non-static objects like pedestrians. To address these issues, we propose NeRF-MS, a approach training NeRF with multi-sequence...
