Kind Code:
A1
Abstract:
The present application provides a battery, an electrical apparatus, and a method and device for manufacturing the battery. The battery comprises: a housing body comprising side walls that enclose and form an accommodating cavity; a battery cell group arranged in the accommodating cavity and comprising multiple battery cells, the multiple battery cells being stacked one on another; an end plate arranged in the accommodating cavity and located between the battery cell group and a side wall; an electricity lead-out member used for leading out the electric power of the battery cell group, the electricity lead-out member comprising a first section, a second section, and a third section which are connected in sequence, the second section being embedded into the end plate, the first section and the third section extending out of the end plate, and the first section being electrically connected to the battery cell group; and/or a sampling unit used for collecting signals of the battery cell group, the sampling unit penetrating through the end plate, and one end of the sampling unit being connected to the battery cell group. According to the technical solution of the present application, the battery structure is highly integrated, facilitating the space utilization rate of the battery, thereby enhancing the energy density of the battery, and facilitating the connection stability of the electricity lead-out member and the sampling unit.
