Abstract: This disclosure provides a battery, an electric device, a manufacturing method and a manufacturing system for the battery. The battery includes a battery module, a casing, and a flow guide member. The battery module includes an explosion-proof assembly. The casing accommodates the battery module. The casing includes a gas discharge passage. The gas discharge passage includes a gas inlet and a gas outlet. The flow guide member is disposed inside the casing and shields the explosion-proof assembly to form a gas guide passage. The gas guide passage is in communication with the gas inlet, for guiding gas generated by the battery module to an exterior of the casing through the gas outlet after the explosion-proof assembly is destroyed. This disclosure intends to solve the technical problem of use safety of the battery being seriously affected due to the battery being prone to catching fire quickly and then exploding.
