Single-crystal Cathode Materials

CATHODE MATERIAL

Single-crystal Cathode Materials

In this era of eco-friendly batteries, we are leading the way with the world's best single-crystal cathode materials

We produce cathode materials, one of the four core materials of rechargeable batteries, using “single-crystal” and “dry” processes. We have a unique technology that enables all anode materials to be made into single crystals High Capacity, High Output, High Safety Nickel Cathode (Ultra high-Ni, Co-free Mid-Ni, Co-free LMR, Precursor free ultra high-Ni)

Ultra high-nickel cathode material

① Single particle size : 3~5 ㎛

② High initial capacity (> 220mAh/g with a 4.25V cut-off at 0.2C rate)

③ High-pellet density (no particle collapse under 6 ton/cm)

④ Excellent thermal stability (onset temperature above 220°C)

Lithium & Mn-Rich Cathode Material

① Single particle size : 1~2 ㎛

② High initial capacity (270mAh/g with a 4.7V cut-off at 0.1C rate)

③ High electrode density (maximum electrode density of 3.3g/cc)

④ Excellent low-temperature performance and minimal voltage drop during cycle

⑤ High thermal stability (onset temperature above 250°C)
