With an energy density estimated to be 2-3 times that of current products, all-solid-state batteries are expected to achieve scaled mass production around 2027. This is no longer a lab concept but a next-generation technology entering the production validation phase. In this critical window, whoever solves the key material bottlenecks will seize the initiative in the imminent market.
“Revenue from copper foil for solid-state batteries is projected to grow from RMB 4.96 billion in 2024 to RMB 18.08 billion in 2031, with a compound annual growth rate of 22.1%.” This report from market research firm Hengzhou Chengsi clearly illustrates the immense potential of the copper foil market for solid-state batteries.
The rapid development of solid-state battery technology is placing entirely new demands on upstream materials, as traditional copper foil can no longer meet these emerging needs.
01 Industry Transformation
Solid-state batteries are becoming a new global focus for the energy transition. Compared to traditional lithium-ion batteries, solid-state batteries replace liquid electrolytes with solid ones, fundamentally addressing safety hazards like flammability and explosiveness while theoretically increasing energy density to 2-3 times that of existing products.
As automakers like Dongfeng, Changan, and SAIC successively announce their timelines for integrating solid-state batteries into vehicles, the installation process is accelerating comprehensively.
According to industry forecasts, global shipments of solid-state batteries are expected to rise to 614 GWh by 2030, with the market size potentially exceeding RMB 110 billion. This growth will not only drive a comprehensive upgrade of the lithium battery industry chain but also lead to a significant increase in material value.
The development of solid-state batteries is accelerating. It is estimated that by 2030, the annual growth rate in copper foil demand will exceed 20%, with room for price increases for high-end products.
02 Technical Challenges
Solid-state battery technology imposes unprecedented stringent requirements on copper foil materials.
In traditional lithium-ion batteries, liquid electrolytes can fully permeate the contact surface between the electrode and the copper foil. In solid-state batteries, all components are solid, and the physical contact between the electrode and electrolyte is point-to-point, resulting in a much smaller effective contact area than in traditional battery interfaces. This leads to a significant increase in interface impedance.
This severely impacts the battery’s power output and charging performance and imposes higher demands on the current collector material.
Particularly in sulfide-route solid-state batteries, copper foil faces even more severe corrosion issues. The reaction between sulfide electrolytes and copper causes corrosion, requiring copper foil to possess stronger corrosion resistance.
Furthermore, the high-temperature operating environment of solid-state batteries also places greater demands on the thermal stability of copper foil. Traditional copper foil experiences strength degradation and structural deformation at high temperatures, making it difficult to meet the requirements for long-term stable operation of solid-state batteries.
03 Material Innovation
Facing the technical challenges posed by solid-state batteries, the industry is actively exploring various innovative copper foil solutions.
Nickel-plated copper foil has become a key solution to the corrosion problem in sulfide solid-state batteries. Through nickel plating, a protective layer forms on the copper foil surface, effectively preventing corrosion reactions between sulfide electrolytes and copper. Research institutions predict that the market size for nickel-plated copper foil will reach approximately RMB 6 billion by 2030.
Porous copper foil is also an important development direction for solid-state battery applications. NuoDe Co., Ltd. successfully developed porous copper foil as early as 2018, with pore sizes ranging from 30 to 120 microns and porosity rates from 20% to 70%.
Innovative products like alloy foils and surface-coated copper foils also provide new ideas for solving interface issues and enhancing the thermal stability of solid-state batteries.
