Global Conductive Agent for Solid State Batteries Market Growth Forecast Report 2025-2031

Conductive agents for solid-state batteries are functional materials added to the positive and negative electrodes, electrolyte composite layers and other parts of solid-state batteries to improve electron transmission efficiency, improve interface contact and inhibit polarization. They are usually carbon-based materials (such as carbon nanotubes,conductive carbon black, graphite, graphene)or their composites.

According to the recent report by Global Info Research, the global market for conductive agents used in solid-state batteries is set to witness rapid growth, with projections showing an increase from USD 62.8 million in 2024 to USD 217 million by 2031, reflecting a robust compound annual growth rate (CAGR) of 20.5% during the forecast period (2025-2031).

Latest Trends
Carbon Nanotubes Replacing Carbon Black
In 2025, multiple studies have demonstrated that replacing traditional carbon black (such as Super P) with multi walled carbon nanotubes (MWCNTs) in composite electrodes yields significantly improved conductivity and structural integrity. In one recent experiment, MWCNT infused cathodes exhibited electron conductivity nearly double that of carbon-black equivalents, allowing manufacturers to reduce additive loading and increase active material proportion. Markets reports confirm that, although carbon black remains the fastest growing conductive agent type in lithium ion cathodes, CNTs are regaining market share due to their superior performance to cost ratio and growing investment in scalable CNT production facilities globally.

Dry Electrode Manufacturing
Dry battery electrode (DBE) processes-such as PTFE-based fibrillation and powder to film extrusion-have gained traction as environmentally efficient alternatives to wet slurry methods. These solvent free techniques eliminate drying steps, lower energy consumption, and enable finer control over conductive-agent dispersion and alignment. In all solid state battery prototypes, dry-film electrodes have shown more uniform microstructure, reduced charge transfer resistance, and easier integration of carbon-based additives like CNTs within the electrode matrix. Industry reviews published in early 2025 expect dry processing to support high loading and scalable solid state cell production.

Interface Optimization and Space Charge Layer Effects
Researchers are now applying advanced interface engineering to address compatibility issues between carbon conductive agents and sulfide solid electrolytes. A recently proposed method involves coating carbon fibers (e.g. VGCF) with a thin layer of halide electrolyte (Li3InCl6), which suppresses parasitic reactions and stabilizes the interface. Cells using VGCF@Li3InCl6 achieved areal capacities around 7.7 mAh/cm2 and retained nearly 78 percent capacity after 400 cycles. Separately, a space charge layer effect discovered in mid 2025 shows that mixing two different solid electrolytes at particle boundaries can form interfacial zones that facilitate faster ion transport than either material alone. Both strategies point toward significant gains in interfacial ionic kinetics and long-term cycling stability.

Regional Momentum in Asia Pacific, Europe and North America
The Asia Pacific region-especially China, Japan and South Korea-continues to dominate production and adoption of conductive agents in solid state batteries, driven by large-scale battery manufacturers and CNT producers investing in new capacity. Simultaneously, Europe has seen strategic expansion: OCSiAl opened its first European graphene nanotube facility in Serbia in late 2024, with annual capacity set at 60 tonnes and plans to scale to 120 tonnes by the end of 2025. In North America, partnerships and pilot lines with automakers such as GM and Ford are integrating CNT based conductive layers into quasi solid state cell prototypes, indicating growing regional focus on solid state commercialization.

Regional Highlights
The Asia-Pacific region remains the manufacturing hub, especially China, Japan, and South Korea. Meanwhile, Europe sees increased demand from electric vehicle and aerospace sectors, driven by initiatives from companies like BMW, Toyota, and Airbus.
North America is focusing on scaling commercial pilot lines, with investments from both startups and major players like General Motors and Solid Power incorporating CNT-rich conductive layers.

As solid-state battery development enters commercialization phases, the need for highly conductive, stable, and process-compatible conductive agents is escalating. The next few years will see increased collaboration across the value chain-from materials science companies to EV manufacturers-to ensure performance and scalability of solid-state energy storage solutions.
