Development of electrolyte of the secondary battery, development of quaternary ammonium compounds used for various types of polyurethane
A secondary battery, which is rechargeable, consists of cathode, anode, separator, and electrolyte. Among them, electrolyte works as a transferable medium that rapidly transfers metallic ions from anode to cathode while being charged, whereas it moves from cathode to anode when discharged. Therefore, conductivity and electrochemical stability of metallic ion are required. Lithium-ion battery, which is on the market currently, is made of carbon at the cathode, transferred metallic oxide at anode and the organic electrolyte. In particular, the performance of organic electrolyte decides the density of high-energy, life-span, and stability. This is why the development of organic electrolyte additives is quite significant.
Using the quaternary ammonium compounds as strong organic or basic catalyst to adjust ph and prevent undesirable reactions. These chemical compounds, which can be used for various reactions, prevent the addition of metallic pollutant and problems regarding the common volatile compounds. Pyuran Co., Ltd. has a large scale of experience about phase-transfer catalysts (PTC) field. We have diverse polymer, quaternary ammonium compounds that are used for the epoxy manufacturing process, in particular. As well, quaternary ammonium compounds are also used for the production of polycarbonate, polyester, silicone, polyurethane, and rubber. We focus on quaternary ammonium compounds that are used for the production of the integrated circuit, flat panel display, printed circuit board, capacitor, sensor, and other various components.
