A battery pole group and a battery

Abstract

The application relates to the technical field of storage batteries, in particular to a storage battery pole group and a storage battery. The storage battery pole group comprises a plurality of positive plates, one end of each positive plate is provided with a positive lug; a plurality of negative plates, one end of each negative plate is provided with a negative lug, the plurality of negative plates and the plurality of positive plates are alternately arranged along a first direction; a plurality of separators are arranged between adjacent positive plates and negative plates and used for isolating the adjacent positive plates and negative plates; the positive lug of a first end positive plate and / or the positive lug of a second end positive plate is provided with a first bending structure, the first bending structure extends towards a middle positive plate; the negative lug of a first end negative plate and / or the negative lug of a second end negative plate is provided with a second bending structure, the second bending structure extends towards a middle negative plate; in this way, when bus bars are welded, bus bars with a shorter length can meet the requirements, thereby saving the amount of bus bar material and saving costs.
