A rechargeable lithium battery includes a compound represented by Chemical Formula 1: In Chemical Formula 1, each of k, l, and m is independently an integer of 0 to 20, n is an integer of 1 to 7, and k, l and m are selected such that the compound of Chemical Formula 1 has an asymmetrical structure. The compound of Chemical Formula 1 may be included in the positive electrode, the negative electrode, or the electrolyte of the rechargeable lithium battery.

Rechargeable lithium battery

A device for analyzing a film on a surface of an electrode for a rechargeable lithium battery includes: an inert chamber capable of maintaining an inert atmosphere including controlled amounts of moisture and oxygen and including an inner space for pretreating a sample including the film on the surface of the electrode; a first analyzer coupled to the inert chamber through a connection tube, the first analyzer being configured to receive the sample and being configured to provide composition and thickness information of the film; an inert holder configured to be assembled around the sample in the inert chamber and configured to maintain the inert atmosphere around the sample; and a second analyzer mounted with the inert holder therein and configured to provide shape information of the film. A method of analyzing a film on a surface of an electrode using the device is also disclosed.
