abstract
❝　Tremendous effort has been focused on developing electrochemical energy storage devices such as Li-ion batteries (LIBs) and supercapacitors with potential applications such as portable electronics and electromobility. In addition, large-scale energy storage devices for storing renewable energy are also important. Na-ion batteries (NIBs) with lower costs than LIBs are promising as large-scale energy storage devices. This presentation will introduce advanced materials, such as polyoxometalates and high-entropy ceramics for lithium/sodium ion batteries, which can achieve high energy density, fast charge and discharge rate, and long cycle life. To understand the charge storage mechanism of those advanced electrodes, in situ synchrotron X-ray absorption spectroscopy, X-ray diffractometer, and transmission X-ray microscope are conducted. 
❝　Microbial fuel cells (MFCs) and plant microbial fuel cells (PMFCs) are energy devices that convert chemical energy into electrical energy through microbial metabolism. However, MFCs and PMFCs are suffering from low power density and high cost. We used various biowaste-derived porous carbons as electrodes to increase surface roughness and biocompatibility, thus improved the adhesion of microorganisms and the electron transfer, resulting in high-power density.　❞
