GanFeng Lithium's 500Wh/kg Solid-State Battery Enters Small-Batch Production

Chinese lithium giant GanFeng Lithium has disclosed a series of significant technical and commercial milestones in its latest investor briefing, signaling that the company's solid-state battery ambitions are moving well beyond the laboratory. Most notably, the firm confirmed that its 500Wh/kg-class solid-state battery — widely regarded as a world first at this energy density — has entered small-batch production, setting a new industry benchmark for lithium-metal battery commercialization.

eVTOL Integration Marks Low-Altitude Economy Milestone

On the commercial application front, GanFeng's high energy-density, high-power battery has been integrated into the AE200-100 aircraft developed by Wofei Changkong (AutoFlight), a Chinese electric vertical take-off and landing (eVTOL) company. The battery successfully powered the aircraft through its first phase of crewed flight testing in 2025, giving GanFeng an early-mover advantage in the rapidly emerging low-altitude economy sector.

The successful crewed trial represents a pivotal step in translating solid-state battery chemistry into real-world aerospace applications, an area where energy density and safety margins are non-negotiable.

Dual Technology Roadmap: Silicon Anode and Lithium Metal

GanFeng is pursuing two parallel solid-state battery technology tracks simultaneously, a strategy the company says is designed to address diverse application requirements.

Lithium Metal Anode Route

The company's second-generation semi-solid (solid-liquid hybrid) battery uses metallic lithium as the anode. GanFeng's existing metallic lithium product lines also serve as anode materials for fully solid-state cells, creating vertical integration synergies that the firm says will support future industrialization.

Progress on this route is substantial:

• The 400Wh/kg cell has exceeded 1,100 cycle life and completed engineering validation, signaling readiness for scale-up.
• The 500Wh/kg, 10Ah product — described as a global first — has entered small-batch production, establishing a commercialization landmark for the industry.

Silicon-Based Anode Route

In parallel, GanFeng's silicon anode program spans a gradient product portfolio from 320Wh/kg to 480Wh/kg, allowing the company to serve different markets simultaneously:

The 480Wh/kg silicon-anode cell is described as representing the frontier of the industry, positioning GanFeng competitively against domestic and international rivals including CATL and QuantumScape.

Global Mining Portfolio: Africa, South America, and Beyond

Beyond batteries, GanFeng's investor briefing addressed the operational status of its international lithium resource projects, which are critical to the company's long-term self-sufficiency strategy.

• Mali Project: Production operations and logistics remain normal. The company acknowledged security sensitivities and stated it will strengthen coordination with local government authorities to ensure project continuity.
• Argentina – Caucharí-Olaroz Phase II: The project has received approval under Argentina's RIGI incentive framework, with local authorities actively supporting its development through favorable policy conditions.
• Sierra Leone – Bambali Lithium Project: Expected to begin gradually releasing capacity next year, with an annual raw ore mining capacity of 2 million tonnes.

2026 Outlook: Cost Reduction and Capacity Expansion

Looking ahead, GanFeng has outlined an aggressive agenda for 2026 centered on cost reduction, efficiency improvement, and capacity deployment. Key priorities include:

1. Enhancing production efficiency through process innovation and technical upgrades.
2. Increasing the company's lithium resource self-sufficiency ratio to reduce dependence on spot market procurement.
3. Prioritizing production ramp-up at the Mariana and Goulamina lithium resource projects.
4. Accelerating the construction and commissioning of battery manufacturing bases, with Nanchang as a key hub.

FAQ: GanFeng Lithium Solid-State Battery

What makes GanFeng's 500Wh/kg battery significant?

The 500Wh/kg energy density represents a major leap beyond the 300–400Wh/kg range typical of current commercial lithium-ion cells. At this level, electric aircraft and long-range EVs become significantly more viable. GanFeng's claim of small-batch production — not just prototype demonstration — distinguishes this announcement from many competitor claims that remain at the lab stage.

How does the 400Wh/kg cell compare to existing EV batteries?

Most high-performance EV batteries today operate in the 250–300Wh/kg range. A 400Wh/kg cell with over 1,100 cycles of verified engineering endurance would offer roughly 30–60% more range or a proportionally lighter pack — a transformative improvement for electric vehicles and aviation alike.

When will GanFeng's solid-state batteries reach mass market?

GanFeng has not announced a specific date for full-scale consumer commercialization. The current small-batch production phase for the 500Wh/kg product and engineering validation for the 400Wh/kg cell suggest that broader industrial deployment is the next milestone, likely within the next two to three years based on the company's stated 2026 priorities.

What is the RIGI framework mentioned for the Argentina project?

Argentina's RIGI (Régimen de Incentivo para Grandes Inversiones) is a large-scale investment incentive program designed to attract foreign capital into strategic sectors such as mining and energy. Approval under RIGI typically grants tax benefits, regulatory stability guarantees, and streamlined export procedures — making it a meaningful endorsement for GanFeng's Caucharí-Olaroz Phase II expansion.

Conclusion

GanFeng Lithium's May 2025 investor briefing paints a picture of a company executing on multiple fronts: pushing the boundaries of solid-state battery energy density, securing real-world validation in eVTOL applications, and steadily building out a globally diversified lithium supply chain. The world-first 500Wh/kg small-batch production milestone is the headline, but the broader story is one of systematic industrialization across technologies, geographies, and application verticals.

As the battery industry accelerates toward next-generation chemistries, GanFeng's dual-track technical approach and vertical integration from lithium mining to cell manufacturing may prove to be a decisive competitive advantage.
