In lithium-ion batteries, the electrochemical instability of the electrolyte and its ensuing reactive decomposition proceeds at the anode surface within the Helmholtz double layer resulting in a buildup of the reductive products, forming the solid electrolyte interphase (SEI).
In order to gather a more comprehensive and solid knowledge of the interphases in Li-ion batteries, especially on the positive electrode side, it is therefore of vital importance to systematically study such surface layers through the hyphenation and the combination of several analytical tools.
An in-depth historical and current review is presented on the science of lithium-ion battery (LIB) solid electrolyte interphase (SEI) formation on the graphite anode, including structure, morphology, composition, electrochemistry, and formation mechanism.

Lithium-ion battery (LIB) is the most popular electrochemical device ever invented in the history of mankind. It is also the first-ever battery that operates on dual-intercalation chemistries, and the very first battery that relies on interphases on both electrodes to ensure reversibility of the cell chemistries.
(6) Battery interphases are typically studied by applying ex situ techniques on individual electrodes before and after electrochemical cycling, e.g., X-ray photoelectron spectroscopy (XPS) or cryogenic transmission electron microscope (cryo-TEM).
