Stabilization of Cathode-Electrolyte Interface in a High-Voltage Lithium-ion Battery |
| 초록 |
Li-rich and Mn-rich layered oxide cathode material is known to deliver high specific capacities ≥ 250 mAhg−1 on the high-voltage operation above 4.6 V vs. Li/Li+ by de-intercalating more number of Li+ ion. This point makes this material as a promising cathode active material for advanced high-energy density Li-ion batteries. The limited anodic instability of conventional carbonate-based organic electrolytes above 4.2 V vs. Li/Li+ however makes the attainment of high-capacity difficult. To mitigate the anodic instability problem of conventional electrolyte, we have been developing new high-voltage electrolyte components to stabilize high-voltage interface between Li-rich layered oxide cathode and electrolyte. Studies of high-voltage electrochemical processes and cathode-electrolyte interfacial phenomena and their relations to cycling performance would be discussed. |
