Investigation of 2D material anodes with different anions for lithium ion batteries: comparison of MoO2, MoS2 and MoSe2Chen, Tianrui

The energy storage devices used in today’s society are mainly lithium batteries. At present, the anode material of commercial lithium batteries is generally graphite. Although lithium battery has superior performance compared with other energy storage methods, it still has many problems, such as poor safety, low specific capacity, and slow charging speed. In recent years, although some researchers have proposed graphene as anode material, the results show that although graphene can partly alleviate the above problems, it cannot meet the needs of industrial and domestic applications. Therefore, we investigate the properties of MoO2, MoS2 and MoSe2 as battery anode materials. These three materials have good conductivity, and anions are the same main group. The effects of anionic electronegativity on battery performance can be compared and discussed. We obtain the binding energy, diffusion barrier, voltage, stable adsorption site and corresponding charge transfer of Li on the above three materials by first-principles calculations. We find that MoO2, MoS2 and MoSe2 have their own advantages and disadvantages as battery anode materials. MoO2 has the strongest binding capacity with lithium ion and the closest adsorption degree. MoS2 is slightly inferior and MoSe2 has the weakest binding capacity. This feature will lead to MoO2 having higher specific capacity and the ability to prevent lithium dendrite growth. However, considering the lower diffusion barrier, lithium ion in MoSe2 is easier to diffuse and the charging rate of the MoSe2 based lithium battery would be higher, while lithium ion in MoO2 is not easy to diffuse and the charging rate could be low. In general, the three anode can improve the battery performance in different aspects, and have a wide application prospect.

Inlet air filtration of ships and coastal installations is mainly used to filter out salt aerosol particles, so researches on the inlet filter needs to simulate spray aerosol state in the marine environment. The sea salt aerosol particles have multiple sizes, thus salt aerosol generator should have the ability to produce salt aerosol particles of various diameters. This paper investigates the factors that affect the particle diameter of a salt aerosol generating device. Numerical simulations on the two-phase flow in a salt aerosol nozzle are conducted and the influence of air inlet pressure and droplet mass flow rate on the particle diameter is discovered. The results show that the particle diameter of the aerosol nozzle decreases with the air inlet pressure increasing and the droplet mass flow rate decreasing.

Surface roughened polyvinyl alcohol (PVA) nanofibers are produced by electrospinning and selective dissolution in ethanol. By electrospinning of PVA (Mw 74885) and polyvinylpyrrolidone(PVP) (Mw 44000-54000) blend solution, PVA/PVP blend nanofibers with smooth, homogenous surface are prepared. Then the surface roughened nanofibers are achieved via selective dissolution in ethanol. Fourier Transform Infrared Spectra (FTIR) and Energy Dispersive Spectrometer (EDS) result shows a complete removal of PVP from blend nanofibers. In this work, PVA/PVP is the first water-soluble polymer combination adopted to create surface roughened nanofibers by selective dissolution. Moreover, opposite to other selective dissolution schemes which removes polymers of higher Mw, this is the first time creating surface roughened nanofibers by selectively removing polymer of lower Mw successively. Through selective dissolution, rough structures appear on the ultra-fine PVA-PVP nanofibers surface. The successive preparation of surface roughened PVA nanofiber can be attributed to the mobility of PVP molecule. The method claimed in this paper is helpful for developing more types of surface roughened nanofibers in the future.

With the rapid development of modern society, the application of intelligent unmanned vehicles is becoming more and more popular. Based on the scene of unmanned vehicle patrol operation in an intelligent warehouse and simplifying it, this paper designs an image processing and perception of driving road conditions with ATM89C51 single-chip microcomputer as the core, camera, and infrared sensors to realize the detection of car trajectory. Two groups of four DC motors are set to drive, and the turning is carried out through the differential speed of the wheel motors on both sides. The turning radius and turning time are shortened through the independent control of the motors on both sides. The L298N full-bridge motor drive core is used to control the speed of the motor, to realize the accurate control of the trolley movement, and lay the foundation for the intelligent operation of the trolley in more scenarios. The accuracy of car navigation and motion control is improved through dual sensors.

Aiming to the switching characteristics of SiC optically controlled transistor, SiC NPN optically controlled transistor was investigated through Silvaco TCAD. The results show that under 4500V bias voltage, the turn-on and turn-off dV/dt of the SiC transistor are 428.5V/ns and 23.9V/ns, respectively. And the tailing problem in the turn-off process is obvious. In order to improve the switching characteristics of SiC optically controlled transistor, the minority carrier lifetime in base layer is regional controlled. The simulation results indicate that, by using minority carrier lifetime control technology, the turn-off time and turn-off dV/dt are improved by about 28.2% and 39.3%, respectively. Meanwhile, turn-on time and turn-on dV/dt are only degenerated by about 3.6% and 3.4%, respectively. The overall level of switching characteristics of SiC optically controlled transistor are improved.

In order to deal with the problem of energy shortage, demand side management has attracted more and more attention. Taking demand side resources as an example to understand the regulation potential of demand side resources, this paper designs a hierarchical and partitioned dynamic regulation architecture for demand side adjustable resources, which can carry out the interconnection between multi-level subjects and efficient information interaction. The regulation potential prediction model of elastic load is established through the hierarchical and partitioned architecture, and the credible and adjustable potential of resident users under two regulation scenarios is obtained through calculation: participating in emergency load reduction and peak valley difference, which proves the effectiveness of the architecture.
