Electrochemical cell

An electrochemical cell configured to provide at least occasionally electrical energy, comprising:

• at least one negative electrode including at least one material which is capable of absorbing charge carrier in the form of lithium ions during charge processes;
• at least one positive electrode including at least one material which is capable of releasing charge carrier in the form of lithium ions during charge processes;
• and
• at least one electrolyte, which is capable of transporting charge carrier, in the form of lithium ions, between the at least one negative electrode and the at least one positive electrode;
• and
• at least one protective device, wherein the protective device is an integral part in at least one of the at least one negative electrode and the at least one positive electrode and comprises at least one enclosure,
• wherein the at least one protective device is configured such that if a damaging influence in the form of heat damaging the electrochemical cell occurs, at least one stabilizing additive is released from inside the at least one enclosure.
