Proposal for lithium-ion secondary battery binder! Achieving high adhesion and low resistance! Peel strength increased by 1.7 times compared to our conventional product AN-136K!
<AN-145A> Our company has refined the synthesis technology of water-dispersible polymer microparticles known as "core-corona type microparticles," focusing on their application in the battery field. In response to requests to "minimize the use of binders to reduce electrode resistance and improve charge-discharge characteristics," we have newly developed "AN-145A," which can further enhance the peel strength of electrodes. The newly developed product has shown approximately 1.7 times the peel strength improvement compared to our conventional product "AN-136K," and about three times compared to commercially available SBR, by optimizing polymer design. SEM images also show that binder particles are uniformly dispersed on the surface of the active material, which is expected to contribute to reducing electrode resistance. It is a water-based binder that can be used in the same way as SBR.

Company information
Since our founding in 1950, we have operated as a functional chemical manufacturer centered on surfactants and fine chemicals, with the motto of responding meticulously to our customers' needs. In particular, we possess extensive knowledge of high-performance water-soluble cationic polymers and boast a diverse range of product variations. Our main applications include battery fields, where we provide binders for electrodes, and in the cosmetics sector, we supply hair quality improvement agents for shampoos, conditioners, and treatments. In the environmental (water treatment) field, we offer dye wastewater decolorizing agents, coagulation and sedimentation accelerators, and polymer coagulants. In the paper industry, we provide dye fixation agents, pitch control agents, and water filtration and yield improvement agents. In the textile processing field, we supply dye fixation agents, surface modifiers (cationization agents), and antibacterial agents. We have obtained ISO 9001 certification. Furthermore, we have been recognized by the Ministry of Economy, Trade and Industry as a "Regional Future Leading Company for 2017" and as a "Health Management Excellent Corporation for 2021." In the overseas market, we are advancing our global expansion by responding broadly to the needs of local customers, as well as our Japanese customers, primarily through our subsidiary in Thailand.
