Abstract

The invention provides a multi-pole-set battery. The multi-pole-set battery comprises a battery case and a battery case upper cover, wherein the battery case is used for containing a battery core, and the battery case upper cover is used for packaging the battery case; the battery case upper cover comprises a positive pillar, a negative pillar and the battery core, the battery core is placed into the battery case; the battery case upper cover further comprises at least one separation board, and the separation board is used for partitioning the battery case into at least two containing spaces; the battery core at least comprises two pole sets, each pole set comprises a positive pole lug set and a negative pole lug set, the pole sets are connected in parallel by the pole lug set of the pole sets through a pole set connecting component, and each pole set is respectively placed into the containing space; and the pole set connecting component is correspondingly connected with the positive pillar and the negative pillar of the battery case upper cover. The invention further provides a manufacture method of the multi-pole-set battery.

Description

technical field [0001] The invention belongs to the field of batteries, and relates to a multi-pole group secondary battery and a manufacturing method thereof. Background technique [0002] Lithium-ion secondary batteries are becoming more and more high-energy, and their applications are becoming more and more extensive. In addition to mobile phones, notebook computers, electric tools and other applications, the application of power batteries has shown an upward trend in recent years, especially the development and application of electric bicycles, hybrid vehicles, and pure electric vehicles has become a hot spot. [0003] Large-capacity plastic case batteries generally have a height of 300mm, a width of 600mm, and a thickness of 20-60mm. If such a battery uses one battery cell, even if the stacking method is used, the pole group is also very large. When designing such a battery monopole group, there are pole group stacks due to the long pole piece and the long stroke of th...
