Symbolic Significance PC-EC Disparity

The best example to highlight the importance of interphase is the EC-PC disparity and its impact on the history of Li-ion battery, as shown in Eig. 5.2 [13]. Lithium ion-graphite intercalation compound (LE-GIC) was firstly discovered in early 1950s by H6rold via the reacting graphite with either molten lithium metal or lithium 

As we mentioned the importance of classic interphases above, SEI in Li-ion batteries also plays crucial roles on the performances of the battery, such as controlling the kinetics of cell reaction (charge-discharge rate or power density of the device) determining the reversibility of the cell chemistry and cycle life of the device and affecting the capacity or the energy density and safety performance of device.
