Koiz Files Patent for Cathode Additive Manufacturing Technology for Secondary Batteries

Koiz has filed a patent for a manufacturing method of cathode active materials for secondary batteries, using Meta Titanate (MTA-P), an additive technology for cathode materials.

According to Koiz on June 25, this patent covers a technology for producing cathode active materials for secondary batteries by utilizing MTA-P. The method involves mixing MTA-P with the cathode active material precursor and coating it onto the cathode material composition. This approach improves manufacturing efficiency compared to conventional titanium dioxide (TiO₂) application processes.

MTA-P is a high-purity crystalline particle in a pre-crystallized state before becoming TiO₂. As it can replace certain calcination steps required in existing cathode material manufacturing processes, it is expected to simplify production and reduce costs. In particular, it reduces raw material loss and minimizes the risk of external impurities during the production and transfer of TiO₂ powder, thereby enhancing process reliability and quality stability.

The company expects that this technology will not only maintain battery performance at a level equivalent to conventional TiO₂ applications, but also improve process efficiency, thereby contributing to productivity improvements for cathode material manufacturers.

Currently, Koiz is fostering its advanced materials business for secondary batteries, based on nano metal oxides including MTA-P, as a new growth engine. With this patent, the company plans to accelerate testing procedures with domestic and international battery manufacturers.

A Koiz representative stated, "This patent is not merely the development of a new material, but a technology that can simultaneously enhance both the efficiency and cost-effectiveness of the cathode material manufacturing process. As demand for materials that improve battery stability increases with the spread of AI data centers and the growth of the energy storage system (ESS) market, Ti-based additive materials are attracting attention as key materials for improving the structural stability of high-nickel cathodes."
