The 'Spirit of Innovation' aircraft is the world's fastest all-electric aircraft, setting three world records including a top speed of 345.4 mph over 3km/h.

Aircraft engine manufacturer Rolls-Royce has submitted data to the Federation Aeronautique Internationale (FAI), the federation that has certified the world's aviation and aeronautical records, that the 'Spirit of Innovation' all-electric aircraft can reach the new record was set on 16 November at the UK Ministry of Defence's Boscombe Down aircraft test site. According to company records, the aircraft reached 532.1 km/h (330 mph) in over 15 km, 292.8 km/h (182 mph) faster than the previous record. The International Aeronautical Federation will need to certify and confirm the company's data to make it an official record.

During the record-breaking run, the aircraft reached a top speed of 623 km/h (387.4 mph), according to Rolls-Royce CEO Warren East, who said in a press release: "Winning the all-electric world speed record is a fantastic achievement for the ACCEL team and my company. I would like to thank our team of collaborators, especially Electroflight, with whom we have achieved a pioneering breakthrough. The development of advanced battery and propulsion technology has significant applications in the Advanced Air Mobility market. Following the 26th United Nations Climate Change Conference (COP26), this is another milestone that contributes to the achievement of 'Zero Jet', which strongly supports the great goal of decarbonising air, land and sea transport."

The Rolls-Royce aircraft's power core consists of a 400 kW (500+ hp) electric drivetrain and a core of "the highest power density propulsion battery pack ever assembled in aerospace history". Partners include aerospace energy storage specialist Electroflight and automotive powertrain supplier YASA.

Dr Tim Woolmer, Chief Technical Officer and founder of YASA, said: "Electric aircraft are undergoing the same transformation as jet aircraft did 70 years ago. It's great to be able to see how fast the ultra-high performance, ultra-low weight electric engines will 'Spirit of Innovation' can reach, and how working with ACCEL brings us one step closer to emission-free electric flight."

Lithium-ion batteries (LIB) have become the primary energy storage solution for life in modern society. Among them, lithium iron phosphate batteries are perfect replacements for lead-acid batteries and are even more preferred by industries such as grid-connected peaking, off-grid energy storage, photovoltaic storage, UPS and data centres.
