Summary: The shell thickness of hollow carbon spheres (HCs) has a significant impact on the electrochemical performance due to its effect on lithium ion transport kinetics. A simple one-pot method was developed to synthesize Ndoped hollow carbon nanospheres (NHCs) with different shell thickness (6, 10, and 13 nm) while keeping other parameters almost the same. The NHCs-1 sample with a shell thickness of 6 nm exhibited higher initial charge capacity and better cycle stability compared to NHCs-2 and NHCs-3 with thicker shells of 10 nm and 13 nm, respectively. The capacity dependence on shell thickness was explained by changes in the mass transfer coefficient of Li-ion across the wall. The outstanding electrochemical properties of NHCs were attributed to their unique hollow structure, N-doping, and high specific surface area. The strategy for preparing hollow carbon spheres with different shell thickness provides a promising alternative for developing superior electrode materials for energy storage.

Summary: In this work, nano Sn-SnOx embedded in multichannel hollow carbon nanofibers (Sn-SnOx@MCNF) were found to improve the lithium storage property of tin-based oxides. Sn-SnOx@MCNF exhibited quick ion transfer rate, enough catalytic active sites, high structure stability, little agglomeration, and superior buffering volume change during alloying/dealloying processes. The SnSnOx@MCNF-based electrodes demonstrated predominant reversibility, large capacity, and excellent rate capability during the lithium intercalation process. In practical applications, SnSnOx@MCNF-based electrodes showed a high reversible capacity of 669.2 mAh g-1 even after 600 cycles at 1.0 A g-1 and a high-rate capacity of 525.1 mAh g-1 at 4.0 A g-1. Sn-SnOx@MCNF could be a potential anode material for Li-ion batteries with superior Li-storage performance. Furthermore, a detailed synergistic enhancement mechanism between MCNF and nano Sn-SnOx was proposed.

Summary: Copolymerization of an electron-rich donor (D) unit with an electron-deficient acceptor (A) unit to construct efficient D-n-A-n type donors is an effective strategy for organic solar cell applications. In this work, a series of fused A units with different electron-deficient ability were constructed using benzo[2,1-b:3,4-b']dithiophene and benzopyrazine (BP), benzothiadiazole (BT), and benzoselenadiazole (BS). Three polymer donors were synthesized and their structure-performance relationships were systematically investigated. Among the three polymers, PBDP-BT showed the highest hole mobility. The device based on PBDP-BT:Y6 achieved an outstanding power conversion efficiency (PCE) of 15.14%, surpassing those based on PBDP-BP:Y6 and PBDP-BS:Y6.

Summary: Nitrogen and sulfur co-doped 3D graphene frameworks (NSGFs) with high Na storage capacity were synthesized. The high specific capacity of NSGFs is attributed to the free diffusion of Na ions within the graphene layer and reversible reaction between -C-S-x-C- covalent chains and Na ions. N/S co-doping enhances the Na ion diffusion rate and reduces the electrochemical impedance of NSGFs.
