Topic: Multi-structure Integrated Li-rich Mn-based Oxide Cathodes

Abstract: Li-rich Mn-based layered oxides (LLOs), especially for Co-free one, are one of the most promising cathodes to improve the energy density of Li-ion batteries (LIBs) over 350 Wh kg^-1, which can meet urgent desire of electric vehicles for long duration and low cost. However, serious capacity fading and voltage decay hinders the practical application of LLO cathodes, which originates from surface-related changes, such as oxygen release, TM migration and dissolution, structural evolution and consumption of electrolyte. To this end, this speech will introduce how to construct a robust surface integrated structure for LLOs, and its influence mechanism on electrochemical performance.

Topic: Piezoelectric Energy Harvesting for Low Energy Density Applications

Abstract: Traditional electromagnetic energy harvesting methods are hard to deal with collecting energy from low energy density applications. This speech will introduce several efficient piezoelectric energy harvesting approaches for low energy density applications to overcome this drawback, such as energy harvesting from small hydro, vehicles, and human motion. For example, a bladeless rotational piezoelectric energy harvester was proposed for hydroelectric applications of ultra-low and wide-range flow rates. The proposed harvester makes full use of the advantages of piezoelectric materials and the ancient Chinese Qiqi structure. It overcomes the difficult problem in harvesting liquid energy with (ultra) low energy density through the working principle of intermittent periodic power generation.

Topic: 3D Space-based Seamless Path Planning in Indoor and Outdoor

Abstract: Contemporary living environments are getting more and more complex, combining structures indoor and outdoor. These structures can be broadly subdivided into entirely bounded (indoor), partially bounded (semi-bounded), and unbounded (outdoor). Normally, agents (e.g., pedestrians) wish to have seamless navigation when seamlessly transferring from one kind of environment to another and back. This research developed new theories, models, and approaches to support seamless navigation in all kinds of environments, which include a novel generic space definition framework, a unified 3D space-based navigation model, approaches for automatically reconstructing 3D spaces, and four new path options (MTC-path, NSI-path, ITSP-path, and indoor FD-path). This research brings in four contributions to seamless navigation: (i) living environments (spaces) are systematically categorized and defined as indoor (I-space), semi-indoor (sI-space), semi-outdoor (sO-space), and outdoor (O-space); (ii) all types of spaces are uniformly modeled and managed as 3D spaces, thereby sharing the same approaches for deriving navigation networks; (iii) sI-spaces and sO-spaces are included in navigation maps, which allows developing new path options based on them; and (iv) on the basis of 3D spaces, vertical constraints are considered in navigation path planning.
