On August 17, Rongsheng Menguli New Energy Technology Co., Ltd. held a 300Wh/kg class electric aircraft power lithium-ion battery application announcement. This battery can make the aircraft's cruising range reach 150 minutes. Feng Quanyu, Chairman of Rongsheng Menguli, said that since 2015, Rongsheng Menguli has successively developed a series of new products. The RX1E electric manned aircraft equipped with Menguli batteries has successfully tested and won the approval of the Civil Aviation Administration of my country. Aviation approval has since broken the monopoly of my country’s aviation power lithium-ion batteries by foreign brands. It is understood that Rongsheng Mengguli was established on May 27, 2002, and has established an aviation battery innovation center, which is mainly committed to supplying the best power lithium-ion battery solutions for the aviation field; at the same time, it has been established by Beijing Institute of Technology and Liaoning. The “13th Five-Year Plan” electric aircraft electric propulsion system project of the Ministry of Industry and Information Technology jointly undertaken by General Aviation Institute and Rongsheng Menguli has also started. In the future, Menguli will also prepare to build the company's academician workstation. Yang Fengtian, an academician of the Chinese Academy of Engineering, said that the power lithium-ion battery is the key core component of electric aircraft. In the early stage of the development of the RX1E electric aircraft, the power lithium-ion battery was imported from South Korea, which was not only costly, but also subject to many technical restrictions, which greatly restricted the advancement of this project. Looking at the future industrialization strategy of electric aircraft, the localization of aviation power lithium-ion batteries is imperative. According to the data, from the current technological level, short-distance air travel and commercial sightseeing flights can achieve zero emissions of greenhouse gases through electrification. The efficiency of electric propulsion systems of electric aircraft is two to three times higher than that of traditional fuel engines. The advantages of emission reduction, cost reduction and noise reduction. Under the dual stimulation of environmental protection pressure and economic benefits, the development of global electric aircraft will enter the fast lane. The future market potential is huge. Electric aircraft are becoming another blue ocean after electric vehicles. Statistics show that the electric aircraft market will exceed 22 billion U.S. dollars in the next 15 years. Gaogong Lithium understands that the current important thing is that foreign countries have taken the lead in the electric aircraft market. Boeing, Airbus, British Rolls-Royce, and Germany's Siemens electric aircraft departments have begun to develop hybrid test machines. Boeing has successfully completed the first test flight of its autonomous passenger vehicle (PAV) prototype in Manassas, Virginia. Boeing NeXt is responsible for the company's urban air traffic work, using Boeing subsidiary AuroraFlightSciences to design and develop electric vertical take-off and landing (eVTOL) aircraft, and will continue to conduct tests to improve the safety and reliability of on-demand automated air transportation. Ampaire Inc. (Ampaire Inc.)’s first electric-fuel hybrid aircraft product 'Ampaire EEL' has completed its first flight test, and the company has also received 116 customer orders (including additional purchase options). It is expected to be in 2019. Complete the second upgraded 'EEL' modification by the end of the year, and use the commercial route with Hawaiian Mokulele Airlines to carry out a six-month operational flight test and jointly test pre-production models. It is hoped that FAA Part 23 certification will be completed in 2021 and commercialization will be realized. change. Tesla CEO Elon Musk said that electric airplanes may become a reality within 5 years. He is designing an electric helicopter and estimates that the energy density of lithium-ion batteries will reach 400kg/Wh.
