Developing cathode materials with high specific capability and excellent electrochemical performance is crucial for the advancement of aluminum-ion batteries, which leverage the high theoretical energy density of aluminum metal anodes. In this paper, we investigated the interaction of AlCl4 cluster and Al atom with AlN (-100) and (001) monolayer using density functional theory (DFT) to assess the applicability of AlN as cathode material for aluminum-ion batteries. The results show that the AlN (001) monolayer is the most effective for adsorbing and accommodating AlCl4 clusters. Moreover, the AlN (001) monolayer maintains metallic behavior at different concentrations of the AlCl4 cluster, laying the foundation for its battery application. The theoretical storage capacity of the AlCl4 cluster is 105.93 mAhg-1, which exceeds that of the Al/graphite battery. The formation energy of AlCl4-intercalated AlN compounds is -2.74 eV, and the intercalant gallery height is moderate. Furthermore, the diffusion barrier of 0.19 eV for AlCl4 cluster between the AlN (001) monolayer provides high rate capability. The results indicate that AlN monolayer may be a potential cathode material for aluminum-ion batteries.
Abstract. The purpose of this paper is to navigate and guide the improvement of innovation and entrepreneurship education system in China. This paper focuses on the present status and problem of innovation entrepreneurship education system in Chinese colleges, such as the education concept is backward, the education goal is utilitarian and the mode is unsystematic. Through the comparative study between China and The foreign countries as the United States and Japanese colleges entrepreneurship education system, this paper provides countermeasures to improve the system of innovation and entrepreneurship education in Chinese colleges.
By analyzing the patents licensing data of Huawei, Lenovo, ZTE and Datang in the next-generation information technology industry in China, the following conclusions can be drawn: Huawei and Lenovos technical fields of patents licensing respectively concentrate on the field of the manufacture of assemblages of electrical components, the fields of the speech analysis or synthesis, the speech recognition, the speech or voice processing and the speech or audio coding or decoding, ZTE and Datangs technical field of patents licensing both concentrate on field of the selecting.
With the development of the new generation of information technology industry, the cooperation mode of enterprises become more and more complicated. A research on the technological cooperation is of a significance based on a perspective of patent licensing. By analyzing the patent licensing data of Huawei, Lenovo, ZTE and Datang in the new generation information technology industry in China, we can draw the following conclusions: the patent licensing amount of three companies show the wave declining trend yearly; there are an obvious difference in the distributions of the product patent, the process patent, the product and process patent of patent licensing in the different enterprises; there are an obvious difference in the positions of patent licensing in the different enterprises.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
