-- AetherRun releases first-generation high-voltage LNMO power battery solution with third-party safety and performance data
AetherRun New Energy Technologies Ltd has released its first-generation 4.8-volt lithium nickel manganese oxide (LNMO) Traction battery solution, positioning the technology as a potential third pathway alongside the two chemistries that have dominated the electric vehicle battery market for over a decade: lithium iron phosphate (LFP) and nickel cobalt manganese (NCM) ternary lithium.
The company, based in China’s Hubei province, simultaneously published third-party test reports covering cycle life, rate capability and safety performance. The announcement comes as automakers worldwide accelerate adoption of 800-volt and 1,000-volt electrical architectures, intensifying demand for battery cells that can operate efficiently at higher voltage levels.
Industry context. The global EV battery market has long been split between two mainstream chemistries. LFP cells offer lower cost and strong safety profiles but operate at a nominal voltage of just 3.2 volts per cell, requiring more than 300 cells in series to reach 1,000-volt system voltage. That raises battery management system complexity and pack weight. NCM ternary cells deliver higher energy density but face thermal stability challenges at high nickel ratios, alongside supply-chain exposure to cobalt and nickel price volatility.
LNMO, a spinel-structure cathode material operating above 4.5 volts, has attracted research interest for years as a cobalt-free alternative. However, manganese dissolution at high voltage and limited cycle life have kept it largely confined to laboratories.

Performance data. According to AetherRun’s published test reports, the first-generation LNMO cells retain 97.28 percent capacity at 5C discharge rate and 84.97 percent at 10C, with DC internal resistance of 2.9 to 3.5 milliohms. Under standard cycling conditions at 25 degrees Celsius, the cells surpassed 2,000 cycles with capacity retention above 80 percent. At 45 degrees Celsius, cycle life reached 1,000 cycles.
Cold-weather performance showed 98 percent capacity retention at minus 10 degrees Celsius and 82 to 90 percent at minus 20 degrees Celsius, addressing a persistent concern for EV owners in cold climate regions.
Weight reduction. The company said LNMO’s 4.5-volt platform allows approximately 30 percent fewer cells in series compared with LFP under the same system voltage. In a 150-kilowatt-hour battery system, this reduction in cell count, combined with simplified wiring and cooling hardware, could yield total weight savings exceeding 250 kilograms, or roughly 550 pounds.
Safety testing. Third-party testing under Chinese national standards showed the LNMO cells passed nail penetration (GB/T 31485), thermal chamber (GB/T 38031) and overcharge (GB/T 38031) tests. In nail penetration, a 5-millimeter steel needle pierced the cell center with no fire, no ejection and no explosion. In the thermal chamber test, cells maintained structural integrity after 30 minutes at 130 degrees Celsius. Under overcharge to 115 percent state of charge, no thermal runaway occurred.
Technical approach. AetherRun said its research team addressed the manganese dissolution problem through three coordinated strategies: precursor-stage defect suppression to reduce electrolyte oxidation pathways, gradient coating using atomic layer deposition principles to block manganese ion leaching, and high-entropy lattice doping to strengthen metal-oxygen bonds under high-rate charge and discharge conditions.
Leadership. The company’s chief scientist, Prof. Qie Long, conducted postdoctoral research at the Massachusetts Institute of Technology under Nobel laureate John B. Goodenough, widely regarded as the father of lithium-ion batteries. He has led more than 20 national-level research projects in China. The head of industrial operations, Dr. Ma Mingyuan, holds a doctorate from Tongji University and has 15 years of battery industry experience at companies including CATL and Geely Automobile.
Outlook. AetherRun said it views LNMO as a strategic bridge toward solid-state batteries, noting that solid electrolytes’ wider electrochemical windows are well suited to high-voltage cathode materials. The company projected that combining LNMO with solid-state technology could push cell-level energy density toward 400 Wh/kg.
Industry analysts have noted that while LNMO’s laboratory results are promising, challenges remain in manufacturing consistency and supply-chain maturation before the technology can compete at scale with established LFP and NCM production lines.
