Electrolytes Additives
SK Chemicals has developed a secondary battery material, which delivers much higher performance than existing materials.
The company announced on January 19 that it has succeeded in developing electrolyte additives, which are used to improve the quality of secondary batteries. An electrolyte for secondary battery is a core material, along with anode, cathode, and membrane. An electrolyte serves as the medium in which lithium ions move from the negative electrode to the positive electrode inside the battery, while an additive is used to maximize the performance of an electrolyte.
Since the performance improvement of an electrolyte through high performance additives is directly connected to the improvement of life span, output and safety of secondary battery, its importance is rising.
Electrolytes additives are divided into general-purpose additives, whose patents are expired, and high performance additives, which realizes differentiated performance based on its own patents. As high performance additives requires advanced technology and expertise, such as electrochemical properties-based new material design and synthesis, only three to four American and Japanese companies have monopolized the market until now. SK Chemicals is the nation’s first company that has successfully developed high performance additives based on its own patented technology.
When using the newly developed additives, the life span of secondary batteries extended and secondary batteries delivered higher output than existing products, showing high performance in most indicators. Based on the new additives, SK Chemicals is planning to target the secondary battery material market in earnest.
