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.

Abstract: A battery includes a housing and multiple electrode core assemblies in the housing. Each electrode core assembly includes a packing film and an electrode core located in an accommodating cavity defined by the packing film. A spacer is arranged between two adjacent electrode core assemblies connected in series. Each electrode core assembly includes a first electrode and a second electrode extending out of the packing film. The first electrode of a first electrode core assembly is connected to the second electrode of a second electrode core assembly of the two adjacent electrode core assemblies through a connecting portion in a through hole. The spacer includes an outer surface facing the housing. A first positioning portion is formed on the outer surface, A second positioning portion corresponding to the first positioning portion is formed on the inner surface of the housing and is coupled with the first positioning portion.
