Abstract
A battery includes a housing and multiple electrode core assemblies in the housing. The electrode core assemblies are connected. Each electrode core assembly includes an encapsulation film and an electrode core arranged in an accommodating cavity defined by the encapsulation film. An insulating spacer is arranged between two connected electrode core assemblies and has a through hole. The electrode core assembly includes a first electrode and a second electrode. The first electrode of one electrode core assembly is connected to the second electrode of the other electrode core assembly of the connected two electrode core assemblies at a connecting part accommodated in the through hole. The insulating spacer includes a peripheral surface facing an inner surface of the housing. A metal member is arranged on the peripheral surface of the insulating spacer. The metal member is connected to the housing to fix the insulating spacer with the housing.
