Problems solved by technology

At this time, the contact area between the positive tab and the negative tab on the battery case and the electrode group is small when connected, so the charge per unit area is large, which is not conducive to the improvement of battery power. As a negative electrode current collector, the material cost is high, which makes the production cost of the battery higher, seriously increases the economic expenditure of the battery manufacturer, and reduces the production efficiency

Abstract

The invention discloses a lithium ion battery. The lithium ion battery which comprises a hollow housing (7) is characterized in that: the top of the housing (7), which is opened, is provided with an upper cover (4), and electrode groups (2) are arranged in the housing (7); each electrode group (2) comprises anode sheets (21) and cathode sheets (22), a diaphragm (23) is arranged between one anode sheet (21) and one cathode sheet (22); and each anode sheet (21) comprises an anode current collector (210) and an anode tab (211), and each cathode sheet (22) comprises a cathode current collector (220) and a cathode tab (221). The lithium ion battery disclosed in the invention, which allows the high power charge and discharge to be satisfied, has good safe performances, good cycle performances and good low temperature discharge performances, so the lithium ion battery can be long and safely used by a user, and the lithium ion battery is in favor of the enlargement of the market share of lithium ion battery manufacturers, thereby the lithium ion battery has great production practice meanings.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a lithium ion battery. Background technique [0002] In recent years, with the continuous reduction of oil resources and the increasing environmental pollution, today's automobile industry is facing new technical challenges. In order to reduce the consumption of oil resources and reduce environmental pollution, the world's major automobile manufacturers are actively conducting research on hybrid electric vehicles (HEV) and electric vehicles (EV). Power battery technology has always been the key to restricting the development of hybrid electric vehicle and electric vehicle industry, among which the research on lithium power battery applied to EV and HEV has received more attention. [0003] At present, lithium-ion batteries have the advantages of high specific energy, many cycle times, and long storage time. They are not only widely used in portable electronic devices such as ...
