Zusammenfassung:	An electrochemical device (100) includes a shell (30), an electrode post (10), and an electrode assembly (20). A through-hole (321) is provided on the shell (30). The electrode post (10) is disposed on the shell (30) and at least partially accommodated in the through-hole (321). The electrode post (10) is electrically connected to the electrode assembly (20). A frangible portion (11) is provided at a position corresponding to the through-hole (321) on the electrode post (10). The frangible portion (11) is configured to be burst open when a pressure in the shell (30) reaches a threshold, so as to implement communication between inside and outside of the shell (30) to relieve the pressure. Provided on the electrode post (10), the frangible portion (11) can be broken when the pressure in the electrochemical device (100) reaches the threshold.
