Estimating the term…
Disclosed is an electrochemical device including an electrode assembly having a cathode, anode and an electrolyte, and a casing surrounding the electrode assembly. The device further includes a protection device to which either or both of a cathode lead for connecting a cathode with an outer terminal and an anode lead for connecting an anode with an outer terminal are connected electrically, wherein the protection device is disposed in the inner space of the casing and the electrode lead equipped with the protection device is folded at both sides of the protection device so that the largest surface of the protection device is layered on a lateral surface of the casing where the electrode lead is present.
An electrochemical device comprising an electrode assembly having a cathode, anode and an electrolyte, and a casing surrounding the electrode assembly, which further comprises at least one protection device to which either or both of a cathode lead for connecting a cathode with an outer terminal and an anode lead for connecting an anode with the outer terminal are connected electrically, in series or in parallel, wherein the at least one protection device is disposed at an inner space of the casing and said either or both of the cathode lead and the anode lead equipped with the at least one protection device are folded at both sides of the at least one protection device so that the largest surface of the at least one protection device is layered on a lateral surface of the casing where said either or both of the cathode lead and the anode lead is present.
An electrochemical device comprising an electrode assembly having a cathode, anode and an electrolyte, the electrode assembly being enclosed with a casing having an inner surface and an outer surface, wherein the electrochemical device further comprises at least one protection device to which either or both of a cathode lead for connecting a cathode with an outer terminal and an anode lead for connecting an anode with an outer terminal are connected electrically, in series or in parallel, the protection device is disposed at a sealing region disposed at an inner surfaces of the casing, and the sealing region of the casing is folded so that the sealing region having the at least one protection device is layered on a lateral surface of the casing.
