Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] The embodiment of the present invention provides a power battery tab with a simple structure and capable of realizing electrolyte circulation. see Figure 1 to Figure 3 , the power battery tab 1 is a hollow conductive cylinder, including two opposite ends 11 , 12 , a hollow side wall 13 and a hollow cavity 14 . When used in a battery, the tab 1 of the hollow structure enables the electrolyte to flow in and out.

[0022] As another preferred embodiment of the present invention, one end 11 of the above-mentioned power battery tab 1 is closed, and a hole 15 is provided on the hollow side w...

Abstract

The invention provides power battery pole ears and a power battery. The power battery pole ears are a hollow conductive cylinder. The power battery comprises a casing, an electric core and an electrolyte which are arranged in the casing, a positive pole ear and a negative pole ear which are electrically connected with the electric core, and an electrolyte circulating pump and an electrolyte constant temperature system which are externally arranged on the casing. The positive pole ear and the negative pole ear are the power battery pole ears, one end parts of the power battery pole ears both extends out of the casing, the end part of negative pole ear, which extends out of the casing, is successively connected via an electrolyte guide pipeline with the electrolyte circulating pump, the electrolyte constant temperature system and the end part of the positive pole ear, which extends out of the casing, and an electrolyte circulation channel is formed. The power battery pole ears enable the electrolyte to flow in and out through the hollow pipeline. The power battery is stable in working temperature and high in safety performance.

Description

technical field [0001] The invention belongs to the technical field of power batteries, and in particular relates to a power battery tab and a power battery. Background technique [0002] With the wide application of lithium-ion batteries in power vehicles, mobile phones, notebook computers and other digital products, people's requirements for the performance of lithium-ion batteries are also getting higher and higher. Not only do they hope that lithium-ion batteries have excellent electrochemical properties, Low price also requires lithium-ion batteries to have reliable safety performance. [0003] The shells of existing lithium-ion batteries are divided into metal shells and plastic shells. Metal shells include steel shells and aluminum shells, etc., and non-metallic shells include plastic shells and aluminum-plastic film packaging. In comparison, lithium-ion batteries prepared with non-metallic shells have relatively reliable safety performance. But no matter what kind ...
