Solid state batteries are being accelerated into the hot eVTOL market. Recently, Shanghai Xiba Technology, the Joint Innovation Laboratory of Advanced Materials for Solid State Batteries of the Chinese Academy of Sciences Shanghai Silicate Research Institute and Shanghai Keyuan Solid Energy have completed the joint design of flexible lithium batteries for high specific energy solid state batteries, and have now entered the stage of small batch production. It is reported that the designed energy density of this product exceeds 320Wh/kg, and qualified products will theoretically be the first to be applied in eVTOL scenarios. Recently, global leader in soft pack batteries, Funeng Technology, stated on an investor interaction platform that its semi-solid state batteries have advantages such as high safety, high energy density, high rate, and long lifespan, which are highly compatible with the needs of low altitude aircraft and have gained high recognition from customers at home and abroad. The company's eVTOL semi-solid state battery has entered the industrialization stage.

       Blue Ocean Huateng also stated that the company has invested in solid-state battery enterprise High Energy Era and eVTOL enterprise Lanyi Aviation, and has established strategic collaborative relationships with professional research teams and upstream and downstream enterprises in the industry chain of Harbin Institute of Technology and Xi'an University of Technology, which will accelerate the development of solid-state batteries and low altitude economy.
      EVTOL has been a hot topic in recent years, with a very broad market prospect. According to Morgan Stanley's prediction, the global eVTOL market size will reach $55 billion (approximately RMB 400 billion) by 2030, over $1 trillion (approximately RMB 7.2 trillion) by 2040, and $9 trillion (approximately RMB 65 trillion) by 2050
