Secondary Battery

Secondary batteries work on the principle of generating electricity as lithium (Li) ions move between the positive (+) and negative (-) ends. It can be reused several times through charging and is used as an energy source for eco-friendly mobility including electric vehicles (EV), IT devices, and various household appliances.
A secondary battery is composed of four major elements: cathode material, cathode material, electrolyte, and separator. Kairos Co., Ltd. produces secondary battery materials and supplies them to the global market. We want to grow.

Cathode material refers to the material that forms the (+) pole of the battery, that is, the positive electrode. It is an energy source that serves as a lithium source in lithium ion batteries and determines the capacity and average voltage. Kairos Co., Ltd. is newly producing high-nickel NCM (nickel, cobalt, manganese) anode materials mainly used in electric vehicles, and plans to further expand mass production according to the growth of the electric vehicle market.

As it stores and releases lithium ions, it plays a role in flowing current through an external circuit, and as a material that determines the charging speed and lifespan of secondary batteries, anode materials produced by Kairos Co., Ltd. have a stable structure even during repeated charging and discharging processes. Maintain excellent performance.

All materials of cathode materials composed of various metals such as nickel (Ni), cobalt (Co), manganese (Mn), and aluminum (Al) determine the characteristics of secondary batteries, and are combined with lithium to complete cathode materials. Prices and characteristics vary according to the proportion of each raw material, and research is ongoing for the optimal combination.
