Abstract
⺠High voltage cycling (4.9 V) of lithium rich Li1.2Mn0.525Ni0.175Co0.1O2 cathode. ⺠Surface film formation because of the oxidation of electrolyte. ⺠Studies of surface film using EIS, XPS and micro-Raman spectroscopy. ⺠Increase in cell impedance due to formation of polycarbonates, LiF, LixPFy etc. ⺠Formation of thick surface film is the dominant reason for decrease in capacity.
