POSCO Future M and Factorial Sign MOU to Advance All-Solid-State Battery Technology
Introduction to the Strategic Partnership
The recent Memorandum of Understanding (MOU) between POSCO Future M and Factorial Inc. marks a pivotal moment in energy storage innovation. This collaboration combines Korean materials expertise with U.S. engineering leadership to address critical limitations in lithium-ion battery technology. The agreement, announced on https://www.businesswire.com/news/home/20251203158606/en/POSCO-Future-M-Signs-MOU-with-U.S.-based-Factorial-for-All-Solid-State-Battery-Technology-Development, focuses on developing all-solid-state batteries (ASSBs) capable of 800+Wh/L energy density—double current lithium-ion benchmarks.
Key Players in the Collaboration
POSCO Future M
As a subsidiary of POSCO Group, POSCO Future M specializes in advanced battery materials including lithium iron phosphate (LFP) and nickel-rich cathodes. Their 2023 production capacity of 120,000 tons positions them as a critical supplier to global EV manufacturers.
Factorial Inc.
Factorial's proprietary Atomic Layer Deposition (ALD) technology enables high-precision solid electrolyte coatings. With $380M in venture funding and a 2024 pilot line in Massachusetts, the company has demonstrated 100% Coulombic efficiency in prototype cells.
Understanding All-Solid-State Battery Technology
| Feature | Lithium-Ion | Solid-State |
|---|---|---|
| Energy Density | 200-300 Wh/kg | 400-500 Wh/kg |
| Cycle Life | 1,000-2,000 cycles | 10,000+ cycles |
| Safety | Flammable liquid | Non-flammable |
| Cost per kWh (2024) | $139 | $300 (projected) |
Solid-state batteries eliminate flammable liquid electrolytes, replacing them with inorganic solid conductors. This architecture reduces dendrite formation risk—responsible for 70% of lithium-ion battery failures according to https://about.bnef.com/research/
Strategic Rationale for the Partnership
The MOU addresses three key strategic objectives:
- Material-Process Synergy: POSCO's cathode materials will integrate with Factorial's ALD-coated solid electrolytes to optimize interfacial stability.
- Cost Reduction Targets: Joint R&D aims to cut solid electrolyte production costs by 60% through novel sintering techniques.
- Market Access: POSCO's global supply chain infrastructure will enable rapid commercialization in Asian and North American markets.
Market Implications of Solid-State Battery Innovation
The global solid-state battery market is projected to reach $125 billion by 2035, with early adopters including:
- Automotive: Toyota plans 100,000 unit production by 2027
- Grid Storage: LG Energy Solution targets 5GWh solid-state installations by 2026
- Consumer Electronics: Samsung's 2025 roadmap includes 500Wh/L solid-state phone batteries
