Solid-State Synthesis of NaFe(PO)PO/C by Ti-Doping with Promoted Structural Reversibility for Long-Cycling Sodium-Ion Batteries.

The cathode material NaFe(PO)PO (NFPP) has shown great potential for sodium-ion batteries (SIBs) due to its cost-effectiveness, prolonged cycle life, and high theoretical capacity. However, the practical large-scale production of NFPP is hindered by its poor intrinsic electron conductivity and the presence of a NaFePO impurity. In this study, we propose a mutually reinforcing approach involving Ti doping, mechanical nano treatment, and in situ carbon coating to produce Ti-NFPP via the solid-state methods of synthesis.

Bimetal Oxide Reduction-Induced Perforation Strategy for Preparing a Multi-Microchannel Graphene-Based Anode Material with Rapid Sodium-Ion Diffusion.

A sodium-ion battery, with a wide operating range, is much cheaper and safer than a lithium battery. Graphene is regarded as a promising carbon material in the preparation of anode materials. However, the large two-dimensional (2D) graphene sheets restrain the cross-plane diffusion of electrolyte ions, limiting the further improvement of rate performance.

Verticillium Wilt of Okra Caused by Kleb. in China.

Okra ( (L.) Moench) has gained more popularity as an economically significant plant for its nutritional and medicinal value, especially in China. During 2014-2016, the root disease of okra was discovered in four okra commercial fields surveyed in China.
