W-Scope Korea's main business is the development, production and sales of the separator for lithium ion secondary battery based on our own high molecule film production technology
The separator is used in a wide variety of fields such as Information & Communications, commercial devices, automobiles, industrial devices, and medical treatment, making our lives more convenient and richer.
Structure of Lithium Ion Secondary Battery
The main primary materials for lithium ion secondary battery are anode material, cathode material, electrolyte and separator.
Role of Separator for Lithium Ion Secondary Battery
Lithium-ion secondary separator film is generally used by micro-pore polyolefin film. It takes a roll for securing lithium-ion mobility through internal micro-pore and separating cathode and anode to prevent a short circuit. It also performs very important part to secure safety of Lithium-ion secondary battery such as shut down function which block up micro-pore when thermal runaway happens by internal or external short circuit.
Market for Lithium Ion Secondary Battery
The lithium ion secondary battery is widely used for mobile electronic devices such as mobile phones, laptops and tablet PCs. In addition, the market for lithium ion secondary battery is expanding into eco-friendly vehicles such as hybrid vehicles and electric vehicles, and large-capacity storage devices.
