basic information
**Lecture Summary** Batteries are gaining attention as key technologies for smart grids and electric vehicles. Lithium-ion batteries are strong candidates due to their high energy density, but they face challenges related to resource availability and safety. One potential solution to these issues is magnesium batteries, which are considered a post-lithium battery option. However, there are various challenges to their practical application. In this lecture, I will report on the positive electrode, including the challenges, development status, and materials developed at our center. This material is a hybrid that has been amorphized by dissolving sulfur into the surface of vanadium pentoxide using water plasma. I will present the results of structural analysis and electrochemical properties.
