The landscape of eVTOLs (Electric Vertical Take-Off and Landing aircraft) is rapidly evolving, with orders pouring in, commercialization gaining momentum, and a burgeoning demand for batteries at the GWh scale. Industry experts underscore the stringent standards for aviation-grade batteries, where solid-state batteries have emerged as a frontrunner due to their superior energy density and enhanced safety. However, solid-state batteries still grapple with technical hurdles, supply chain complexities, and cost constraints, hindering their swift commercialization. Consequently, some manufacturers are embracing a hybrid approach, which the industry foresees as a long-term player in the eVTOL sector.
