YapX and Technium Jointly File Patent for Binder Material Used in Secondary Battery Anodes

[Asia Economy Reporter Jang Hyowon] YapX, a KOSDAQ-listed company (CEO Choi Simyeong), announced on the 3rd that it has jointly filed two patents related to anode binders for secondary batteries in collaboration with Technium, a precision chemical materials small and medium enterprise (CEO Baek Yonggu).

Both patents jointly filed by YapX and Technium involve anode binder materials that improve the lifespan and stability of secondary battery electrodes by ▲enhancing initial discharge retention rate ▲suppressing volume expansion of active materials. The companies stated that they are preparing to jointly file additional patents for materials based on differences in compound structures.

The anode materials for secondary batteries consist of three main components: anode binders, active materials, and conductive agents. Among these, the anode binder plays the role of fixing the anode material during charging and discharging. Currently, there is only one company in Korea producing anode binders.

YapX and Technium are currently conducting product sample tests with three major domestic anode material manufacturers. If these sample tests are successfully completed, it will mark the emergence of the second anode binder manufacturer in Korea utilizing the technologies of YapX and Technium.

The companies plan to begin deliveries after completing the sample tests and simultaneously establish their own final mass production system for anode binders.

Technium, which co-developed the anode binder manufacturing technology with YapX, is a precision chemical materials company specializing in the production of core materials for photoresists used in semiconductor photoprocessing. Since last year, Technium has focused on research and development of secondary battery materials and has independently developed multifunctional electrolyte additives with two or more functions such as HF scavenging, electrode protection, SEI formation control, and gas suppression, replacing the previously single-purpose secondary battery electrolyte additives.

Choi Simyeong, CEO of YapX, said, “Both companies have focused on manufacturing and production of core materials in the emerging next-generation key industries of secondary batteries, displays, and semiconductors. Technium possesses abundant R&D know-how based on strong technological capabilities, and YapX specializes in production and manufacturing competitiveness. Therefore, we expect to become one of the very few domestic suppliers of anode binders, which are considered core materials for secondary batteries.”
