Abstract (en)
[origin: WO2012163485A1] Electrochemical cell having at least one negative electrode, at least one positive electrode and at least one electrolyte, wherein the at least one negative electrode essentially has at least one carbon-containing electrochemical active material which is capable of forming a "solid electrolyte interface", that is to say an SEI layer, on at least parts of the surface of the electrode, the electrochemical cell has at least one stabilizing additive which is capable of stabilizing the SEI layer, wherein at least one protective device is provided in the electrochemical cell, said protective device having the at least one stabilizing additive and preferably being designed as a storage container, wherein the at least one stabilizing additive is at least partially released from the at least one protective device when, in respect of the SEI layer, at least one predetermined parameter is reached or exceeded or undershot.
