The 2026 Aviation Propulsion Transformation Seminar was recently held in Shenzhen. Organized by VTOL Circle, the event brought together dozens of aviation propulsion experts and industry leaders to discuss cutting-edge topics including electric motors, hybrid propulsion, battery systems, and airworthiness certification. The development of high energy density lithium battery cells has become a key factor in next-generation aviation and industrial applications.

Dr. Ray, founder of MX Energy Ltd., (parent company of the MXARI brand), was invited to present a keynote titled “Crossing 400 Wh/kg: Key Technologies and Scenario Empowerment of Ultra-High Energy Density Lithium Batteries”, sharing the company’s latest breakthroughs and strategic vision in aviation battery technology.

Rooted in End-User Needs: Building High-Performance Battery Technologies for Real Applications

Dr. Ray emphasized that the R&D of high-performance battery must always start from actual end-user requirements, defining next-generation power systems based on real flight missions.

Based on deep insights into eVTOL, long‑endurance UAVs, and other advanced applications, MXARI has built a clear technology roadmap:

Ultra-high-speed, short endurance scenarios: Optimized LiCoO₂-graphite/SiC system balancing high-rate capability and cycle stability.

High-speed, long endurance scenarios: High-nickel NCM-graphite/SiC system achieving 400–450Wh/kg mass energy density.

Ultra-long endurance, high-speed scenarios: High-nickel NCM-lithium metal system targeting 500Wh/kg.

Validated by Real-World Testing: 400 Wh/kg Battery Performance Demonstration

MXARI is committed to creating measurable value through continuous product iteration. Dr. Ray disclosed several real-world flight test results:

1.4-Hour Endurance Demonstration with 400 Wh/kg Battery System

Equipped with a 400 Wh/kg battery system, the specific UAV model achieved 4 hours of continuous flight under a 33kg payload, retaining 20% battery capacity upon mission completion.

It also demonstrated excellent thermal management, with the module temperature remaining below 50°C.

2.Improving Mission Endurance Through High Energy Density Battery Technology

In another real-world flight test, the UAV achieved a cumulative flight time of 4 hours, 47 minutes, and 40 seconds, covering a distance of over 424.28 kilometers.

The ultimate endurance is now expected to push towards the 5-hour mark.

These results demonstrate that MX Energy Ltd.’s batteries not only deliver high energy density but also maintain robust power output and safety under heavy-load and VTOL conditions.

Advancing High Energy Density Lithium Battery Cell Innovation

“Aviation propulsion transformation is the primary driver of airframe innovation,” said Dr. Ray MX Energy Ltd. will continue to focus on high-performance batteries, seeking the optimal balance between energy density, rate capability, cycle life, and safety.

From liquid lithium to all-solid-state, from 400 Wh/kg to 500 Wh/kg, the company will keep pushing technological boundaries, providing lighter, stronger, and safer power cores for eVTOL, long-endurance UAVs, robots, and other frontier applications.
