Silicon (Si)‐based materials have become one of the most promising anode materials for lithium‐ion batteries due to their high energy density, but in practice, lithium ions embedded in Si anode materials can lead to a maximum volume expansion of nearly three times, which can cause material chalking and shedding, thus affecting the battery cycle life, while the poor electrical conductivity of Si as a semiconductor material also restricts its further development. A lot of research has been carried out based on these problems. This paper reviews the recent research in three aspects: binder, Si surface structure function, and Si carbon composites, summarizes the research lines, methods, and problems of different Si‐based materials, and gives an outlook on their future research.
Intelligent unmanned systems for ground, sea, aviation, and aerospace application are important research directions for the new generation of artificial intelligence in China. Intelligent unmanned systems are also important carriers of interactive mapping between physical space and cyberspace in the process of the digitization of human society. Based on the current domestic and overseas development status of unmanned systems for ground, sea, aviation, and aerospace application, this paper reviewed the theoretical problems and research trends of multi-agent cross-domain cooperative perception. The scenarios of multi-agent cooperative perception tasks in different areas were deeply investigated and analyzed, the scientific problems of cooperative perception were analyzed, and the development direction of multi-agent cooperative perception theory research for solving the challenges of the complex environment, interactive communication, and cross-domain tasks was expounded.
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.
