The fiscal landscape for South Korea’s secondary battery sector is revealing a complex transition. Recent industry data indicates a shift in corporate tax accounting among companies specializing in materials, components, and equipment (often referred to as the “So-Bu-Jang” sector), with reported tax accounting amounts decreasing by approximately 11.2%.
This downward trend in tax accounting comes at a pivotal moment for the industry. While the global electric vehicle (EV) market has faced concerns regarding a slowdown in demand, South Korean equipment manufacturers are simultaneously positioning themselves for a massive next wave of growth. This growth is being driven by the activation of large-scale battery plants in North America and the aggressive pursuit of next-generation solid-state battery technologies.
Among the companies highlighted in recent financial reports, Hansol Chemical reportedly led the group with a tax accounting figure of 31 billion KRW. Other significant figures were attributed to SFA at 18.6 billion KRW, PNT at 18.3 billion KRW, and CIS at 7.6 billion KRW. These figures reflect the current financial positioning of firms that are essential to the battery supply chain, from raw material processing to the final assembly of cells.
Understanding these numbers requires a deeper look at the operational realities of these companies. The secondary battery industry is not a monolith; It’s divided into critical stages—electrode processes, assembly, and activation—each requiring highly specialized machinery. The current volatility in tax accounting likely mirrors the cyclical nature of massive capital expenditures (CAPEX) as companies shift from installation phases to operational stability.
The Strategic Importance of Electrode Process Equipment
To understand why companies like CIS and PNT are central to the battery ecosystem, one must examine the “electrode process,” the initial and most critical stage of lithium-ion battery manufacturing. This process is where the battery’s capacity and performance are fundamentally determined.
The electrode process involves the creation of the anode and cathode. According to industry specifications, this sequence begins with mixing, where raw materials are blended into a slurry. This is followed by coating, where the slurry is applied to a current collector foil at a precise thickness. Next is pressing (calendaring), which uses high pressure to increase the density of the electrode, and finally slitting, where the wide foil is cut into the specific widths required for the battery cells. CIS specializes in the production of these essential coaters, calendars (roll presses), and slitters.
The precision of this equipment is paramount. Any inconsistency in the coating thickness or pressing density can lead to reduced battery life or, in extreme cases, safety failures. This is why battery manufacturers are currently prioritizing “high-precision equipment” to stabilize production yields, leading to a surge in orders for companies that can prove their technical superiority in the electrode stage.
SFA and CIS: A Synergy of Automation and Precision
A significant development in the consolidation of the battery equipment market was the acquisition of CIS by SFA in 2023. This move was designed to merge SFA’s expertise in automation and logistics with CIS’s specialized knowledge in electrode processing.
Under the leadership of CEO Kim Dong-jin, CIS has focused on expanding its production capacity and securing larger order backlogs. Kim, a control design expert and former R&D center head at SFA, has been instrumental in integrating these two entities. His background, which includes roles at Samsung Aerospace and Hanwha Q Cells, brings a rigorous engineering approach to the scaling of battery equipment production. The appointment of Kim Dong-jin as CEO followed SFA’s acquisition of CIS, signaling a strategic pivot toward dominating the electrode process market.
This synergy allows the combined entity to offer a more comprehensive suite of solutions to battery makers, reducing the number of vendors a manufacturer needs to manage and improving the integration between the electrode process and the subsequent assembly lines.
Market Drivers: North American Expansion and Solid-State Innovation
Despite the reported dip in tax accounting figures, the broader market sentiment for battery equipment remains optimistic. This optimism is rooted in two primary catalysts: the North American market and the evolution of battery chemistry.
The United States has become a primary destination for battery investment due to policy incentives and the need for localized supply chains. The operation of massive modern plants in North America is expected to drive record-breaking order backlogs for equipment providers. Companies like PNT, known for their “roll-to-roll” technology, and SFA are seeing renewed momentum as these factories move from construction to equipment installation. Market analysts suggest that the resumption of facility investments by major battery manufacturers is overriding concerns about EV demand slowdowns.
Simultaneously, the industry is preparing for the transition to solid-state batteries. Unlike traditional lithium-ion batteries that use liquid electrolytes, solid-state batteries use a solid electrolyte, which promises higher energy density and significantly improved safety. This shift requires entirely new manufacturing equipment. For instance, the “sintering furnace” technology—used to heat materials to high temperatures without melting them—is becoming a critical competitive advantage. Companies capable of providing high-precision sintering solutions are expected to lead the next cycle of equipment upgrades.
Key Industry Players and Their Roles
| Company | Primary Specialization | Strategic Focus |
|---|---|---|
| Hansol Chemical | Battery Materials | High-capacity material supply |
| SFA | Automation & Logistics | Integrated factory automation |
| PNT | Roll-to-Roll Equipment | High-speed electrode coating |
| CIS | Electrode Process | Coaters, Calendars, and Slitters |
| Wonjun | Thermal Solutions | Solid-state battery sintering furnaces |
What This Means for the Global Supply Chain
The decrease in corporate tax accounting figures for these firms should not be viewed in isolation. In the capital-intensive world of battery manufacturing, tax figures often reflect the timing of revenue recognition and the utilization of investment tax credits. When companies invest heavily in R&D for solid-state batteries or build new factories to support North American clients, these costs can impact short-term tax liabilities.
For the global audience, this indicates that the South Korean “So-Bu-Jang” sector is in a phase of retooling. They are moving away from the first generation of EV battery equipment toward a more sophisticated, high-yield, and next-generation framework. The focus has shifted from simply “building capacity” to “optimizing yield” and “innovating chemistry.”
The integration of companies like SFA and CIS suggests a trend toward vertical integration. By controlling more of the production line—from the initial slurry coating to the final assembly—these providers can offer higher stability and faster deployment times for battery giants looking to scale up quickly in the U.S. And European markets.
Looking Ahead: The Next Checkpoints
The trajectory of these companies will be closely tied to the quarterly earnings reports of the major battery cell manufacturers they serve. The next critical checkpoint will be the upcoming official financial filings for the current fiscal period, which will reveal whether the decrease in tax accounting was a temporary result of investment cycles or a reflection of broader margin pressures.
the industry is awaiting further announcements regarding the commercialization timelines for solid-state battery pilot lines. Any confirmation of large-scale orders for sintering furnaces or new electrode processing tools will serve as a primary indicator of the next growth phase for the sector.
