For Cathode Materials

Normally, cathode active materials of lithium ion secondary battery is synthesized/produced by burning complex oxides consisting of lithium, etc at high temperature. These synthesized elements and production factors of cathode active materials have major effect on sagger’s durability, and sagger also affects the quality of cathode active materials caused by a reaction.

Through a long and through research, we produce/provide excellent saggers with low effects on quality of production due to reaction when synthesizing/producing various cathode active materials and with high durability and thermal stability.
