The present invention discloses a single cell, a battery module, a power battery, and an electric vehicle. The single cell (4100) includes a case, a battery cell accommodated in the case, an electrode terminal (4101) electrically connected to the battery cell, and a cover plate (4102) for encapsulating the case. The electrode terminal (4101) is disposed in the cover plate (4102). The electrode terminal includes a battery post (4104) passing through the cover plate (4102) and electrically connected to the battery cell by using an internal guide member (4196). The single cell further includes a current interrupt device (4200) mounted in the battery post (4104). The current interrupt device (4200) has a flipping member (4202) in communication with gas inside the case. The flipping member (4202) is connected to an outer end surface of the battery post (4104) by using a connection point. The connection point can be disconnected under action of air pressure.
