Abstract Increasing the energy density of Li-ion batteries is crucial for the success of electric vehicles and grid-based energy storage. One of the promising approaches is to increase the capacity of cathode material such as Li-rich layered oxide by increasing the charge cut-off voltage above 4.5 V vs. Li/Li+. The anodic instability of conventional electrolyte however limits its charging to high-voltages. Overcoming this issue relies on electrolyte breakthrough and the stabilization of interfaces of both cathode and anode in a high-voltage battery. In this talk, I will introduce our recent research results on the high-voltage interfacial phenomena of Li-rich layered oxide cathode and graphite anode in a Li-ion full-cell, and their stabilization with high-voltage electrolyte. This work was supported by the Korean Ministry of Trade, Industry & Energy (R0004645).
