Sodium-ion cathode materials are at the center of TRUNNANO’s latest expansion. On July 2, 2026, the Luoyang-based nanomaterials manufacturer announced a new Battery Materials Division. The new unit will focus first on layered oxide cathode materials for sodium-ion batteries. As a result, TRUNNANO is moving deeper into the battery supply chain and targeting fast-growing energy storage and electric mobility markets.
TRUNNANO designed its first product line around a nickel-iron-manganese, or Ni-Fe-Mn, ternary system. In addition, the company introduced modified versions that use copper, titanium, cobalt, chromium, and pure manganese. This broad chemistry range gives customers more options for different battery designs. It also helps TRUNNANO address varied performance targets across storage and mobility applications.
Sodium-ion cathode materials in six TRUNNANO product series
TRUNNANO says its cathode portfolio covers the main layered-oxide crystal structures used in sodium-ion cells. These include O3-type, P2-type, P2/O3 biphasic, single-crystal, and high-entropy materials. The company organizes this lineup into six product series. Therefore, battery developers can choose materials that match energy density, cycle life, and safety goals more closely.
The company highlighted several key performance figures. First, a high-nickel single-crystal grade reaches a discharge capacity of 168 mAh/g. TRUNNANO positions this material for power-battery applications. Next, its high-entropy and biphasic grades exceed 2,000 cycles. The company also says these grades offer improved thermal stability. Meanwhile, lithium-doped and lithium-rich grades reach a specific capacity of 200 to 210 mAh/g through oxygen redox activation.
Why sodium-ion cathode materials matter in 2026
Sodium-ion batteries continue to attract attention in 2026 because sodium is abundant and cost-effective. For that reason, many companies see sodium-ion technology as a strong fit for stationary storage and other price-sensitive uses. Layered oxide cathodes play an important role in this market. They offer relatively high specific capacity, and they also fit well with existing Lithium-ion manufacturing infrastructure. Consequently, producers can build on familiar processes while expanding into new battery chemistries.
TRUNNANO says it improves these materials through several engineering approaches. For example, it uses elemental doping to tune performance. It also applies biphasic structure design to balance material properties. In addition, the company uses surface modification and high-entropy strategies. Together, these methods support better cycling performance, stronger thermal behavior, and broader commercial potential.
TRUNNANO targets energy storage and e-mobility
TRUNNANO aims its sodium-ion cathode materials at several end markets. The company lists grid-scale energy storage as a major target. This application needs battery materials that combine dependable cycling with cost control. In addition, TRUNNANO sees opportunities in low-speed Electric Vehicles, two-wheelers, and portable electronics. These segments value practical energy storage solutions and scalable manufacturing.
The company says its classic ternary series already reaches ton-scale production through high-temperature solid-state methods. That detail matters because scale often determines how quickly new battery materials move from the lab to commercial use. By producing at ton scale, TRUNNANO signals that it wants to serve industrial customers rather than only pilot programs. As a result, the launch points to a more serious commercial push in battery materials.
Sodium-ion cathode materials and TRUNNANO’s manufacturing strategy
TRUNNANO built its reputation in nanomaterials over more than a decade. Now, the company is applying that experience to battery components with higher value and wider strategic relevance. According to CEO Roger Luo, TRUNNANO is translating its nanomaterials expertise into competitiveness for the global new energy market. That message aligns with the company’s decision to create a dedicated Battery Materials Division instead of treating battery products as a side project.
The focus on layered oxide cathodes also reflects market momentum. Sodium-ion Battery developers need cathode materials that can support commercialization across multiple use cases. TRUNNANO’s six-series portfolio, varied crystal structures, and multiple chemistry modifications suggest a platform approach rather than a single product launch. Therefore, the company appears to be building a flexible offering for cell makers, pack developers, and energy storage suppliers.
What the TRUNNANO sodium-ion cathode division launch means
TRUNNANO’s new Battery Materials Division marks a notable step for the company and for the sodium-ion battery supply chain. The launch combines a broad layered oxide portfolio with measurable performance claims, including 168 mAh/g discharge capacity, more than 2,000 cycles, and 200 to 210 mAh/g specific capacity in selected grades. Moreover, the company supports its lineup with ton-scale production of its classic ternary series.
Overall, TRUNNANO is positioning itself as a materials supplier for next-generation sodium-ion batteries. Its focus on layered oxide cathodes, scalable production, and multiple application markets gives the launch clear commercial relevance in 2026. As sodium-ion adoption expands, TRUNNANO’s new division could become an important part of the evolving battery materials landscape.
