Abstract:

With the rapid development of the low-altitude economy, electric vertical take-off and landing (eVTOL) aircraft have placed higher performance demand on batteries. Solid-state batteries, due to their higher energy density and improved safety compared to liquid electrolyte lithium-ion batteries, have become a key technology for addressing the challenges of eVTOL. In this paper, the characteristics of different flight stages of eVTOL and the requirements for batteries are analyzed, with the technological advancements of three types of solid-state electrolytes of polymer, oxide, and sulfide summarized. Considering the practical application of eVTOL, the optimization paths for solid-state battery management systems are explored from the perspectives of electrical, thermal, and pressure aspects. This paper aims to provide a theoretical basis and technical references for the development of high-performance solid-state batteries and management systems that meet the extreme operating requirements of eVTOL aircraft.
