Spinel lithium titanate ( Li4Ti5O12 ), shown to be a superior anode material for energy storage battery, has attracted a great deal of attention because of the excellent Li-ion insertion and extraction reversibility. The high rate characteristics must be amplified before large scale production. A method to overcome this is to prepare electrode materials coated with carbon. A Li4Ti5O12 /Polyacene (PAS) composite were first prepared via an in situ carbonization of phenol-formaldehyde (PF) resin route using TiO2 -anatase, Li2CO3 , and PF resin as precursors by a solid-state reaction. With increasing the current density, the sample still keeps the excellent cycle performance.

State Method

Spinel lithium titanate (Li4Ti5O12) materials were synthesized by a hydrolysis precipitation-assisted solid-state method in the temperature range from 600 to 900℃ for large-scale production. DSC/TGA, XRD and SEM were used to characterize the as-prepared samples. The optimum synthesis condition was examined in relation to the charge–discharge performance. It was found that when the dry hydrolysis precipitation precursor with 8% Li excess was calcined at 700–800℃ for 12 h in air, a pure Li4Ti5O12 phase was obtained. The as-obtained material has the best electrochemical performance due to its narrow size distribution and precise stoichiometry of the oxide.

Hydrogenation Treatment

Hydrogen production through electrolysis has been regarded as one of the most promising solutions for large-scale production of clean fuels. However, most electrodes have large overpotentials in the HER and OER reactions during the water splitting process. Many approaches and methods have been developed to enhance the electrodes' performance. Here, we would like to present our studies on the hydrogenation of various electrode materials for HER and OER applications. We aim to reveal the structure-property-performance relationship for those electrodes after hydrogenation treatment. We wish our work could provide useful information and will be honored if our work can inspire new discovery and finding in the related fields to advance our understanding and technologies for efficient hydrogen production through electrolysis.

Average Size

Particle size effects on the electrochemical performance of the CuO particles toward lithium are essential. In this work, a low-cost, large-scale production but simple approach has been developed to fabricate CuO nanoparticles with an average size in ~ 130 nm through thermolysis of Cu ( OH )2 precursors. As anode materials for lithium ion batteries (LIBs), the CuO nanoparticles deliver a high reversible capacity of 540 mAh g-1 over 100 cycles at 0.5 C. It also exhibits a rate capacity of 405 mAh g-1 at 2 C. These results suggest that the facile synthetic method of producing the CuO nanoparticles can enhance cycle performance, superior to that of some different sizes of the CuO nanoparticles and many reported CuO -based anodes.
