For lithium-ion batteries, it is crucial to equip their electrodes with appropriate adhesives. In fact, adhesives must have sufficient durability and long lifespan, which is an important requirement for electrode use. Basically, adhesives need to have electrochemical stability and chemical inertness in order for lithium-ion batteries to exhibit excellent performance. In addition, PTFE concentrated liquid adhesive exhibits optimal performance by using a smaller amount on the electrode surface.

Among the most common adhesives used in electrode coverings for lithium-ion batteries, polytetrafluoroethylene concentrated liquid adhesives have shown promising results when used as adhesives. As a synthetic fluorinated polymer, PTFE has a high molecular weight composed of carbon and fluorine atoms and is classified as a hydrophobic material, making it inert and unattractive when placed in water or in contact with aqueous solutions. More specifically, this is due to the electronegativity of high pressure London force fluorine.

Adhesive properties of polytetrafluoroethylene

Technically speaking, PTFE adhesive contains CF2-CF2 units, which have good chemical stability and are partially used in lithium-ion batteries. On the other hand, polytetrafluoroethylene concentrate adhesive is considered an environmentally friendly agent that does not produce any harmful effects in the atmosphere where water is used as a solvent, and does not pose any harm or health threat to the human body. Another advantage of polytetrafluoroethylene is its excellent chemical resistance in addition to heat resistance, light resistance, and cold resistance. PTFE also has ideal flame retardancy, low water absorption, and resistance to ultraviolet radiation, exhibiting excellent performance under extreme weather conditions.
