FRIEDRICHSHAFEN,Germany,April 14,2025 --During the 31st AEROFriedrichshafen aviation exhibition in Germany,Montavista Energy Technologies Corporation (Anhui) (referred to as "Montavista") unveiled the latest cycling performance testing result of its high-power electric aviation battery. Using the flight profile provided by an internationally renowned eVTOL manufacturer,Montavista's METARY® P lithium-metal battery (LMB) product,that has a mass-specific energy density of 400 Wh/kg,has demonstrated a long cycle life of over 1,280 cycles with a high capacity retention rate of 99%.

Montavista unveiled the latest cycling performance testing result of its high-power electric aviation battery

For power batteries of electrically-powered aircrafts,comprehensive performance indicators,such as energy density,safety,discharge rate,and cycle life,all directly impact the flight reliability and commercial operational efficiency. High energy density enables longer non-stop flight time,while a long cycle life extends the times that a battery can be reused and thus lowers the operational costs of electric aircrafts. The testing result released by Montavista demonstrates that METARY® P high-power battery delivers not only a high mass-specific energy density of 400 Wh/kg,but also a long cycle life that has not been shown in other LMB products. The exceptional comprehensive performance specifications provide much needed capabilities for commercial application of various electrically-powered aircrafts.

As a pioneer in the field of high-energy electric aviation batteries,Montavista had announced a class of 500 Wh/kg METARY® E series LMB products in 2020,offering an ultra-high mass-specific energy density,suitable for applications such as high-altitude platform station (HAPS) with relatively lower discharge rate demand. In 2023,Montavista launched the high-power METARY® P series products,targeting customers who require both high mass-specific energy density and high discharge rate (>10C),suitable for applications such as eVTOL and drones. Since then,Montavista has collaborated closely with customers to enhance the overall performance of its products. The latest cycling performance breakthrough of METARY® P high-power battery addresses the pain points faced by eVTOL manufacturers and operators for reliable and cost-effective operation in real-world scenarios.

In his keynote speech at "AERO Hydrogen and Battery Summit" during AERO Friedrichshafen,Professor Yuegang Zhang,founder of Montavista,pointed out that the high mass-specific energy density enabled by lithium-metal anode makes the LMB an optimal or irreplaceable choice for future pure-electric aircrafts. Through close collaboration with its customers,Montavista is striving to provide technologies that can help green transformation of the aviation industry.
