Ganfeng Lithium said it has started small-scale production of solid-state batteries with an energy density of 500 watt-hours per kilogram, marking a new milestone in the development of next-generation lithium-metal battery technology.
The company disclosed the update in minutes from an investor relations meeting released on Wednesday.
According to Ganfeng, the product is the world’s first 10 ampere-hour solid-state battery to achieve an energy density of 500 Wh/kg, a level the company said could help accelerate future commercialization of lithium-metal batteries.
The company also reported progress in testing of a separate 400 Wh/kg solid-state battery cell.
Ganfeng said the battery has surpassed 1,100 charge-discharge cycles during testing and has completed engineering validation, suggesting potential for larger-scale commercial applications.
The company said it is pursuing two technological approaches in the solid-state battery sector, focusing on silicon-carbon and lithium-metal anode systems.
Ganfeng added that lithium-metal anode technology remains central to its strategy for developing higher energy-density batteries.
The company said research and development spending accounted for 4.51% of total operating revenue in 2025.
According to Ganfeng, its next-generation solid-state battery products are primarily aimed at premium electric vehicles, robotics, consumer electronics and the emerging low-altitude aviation sector.
The company also said its high-density battery technology has already been integrated into the AE200-100, an electric vertical takeoff and landing aircraft developed by Aerofugia Technology.
Geely has been expanding investments in low-altitude aviation and advanced mobility technologies through Aerofugia.
During the investor meeting, Ganfeng also said it expects global lithium supply and demand conditions to remain relatively tight in 2026 and 2027.
The company attributed the outlook partly to reduced capital expenditure across the lithium industry following several years of declining lithium prices, which it said could limit the pace of future supply expansion.
