Abstract

The invention discloses a safe lithium ion battery. The safe lithium ion battery is characterized by comprising an outer shell (11), an inner shell (20), an upper cover (3), an air release valve (4), a cathode inner bus bar (5) and an anode inner bus bar (6), wherein the inner shell (20) is arranged inside the outer shell (11); the upper cover (3) is connected with the outer shell (11) in a sealing way and is provided with a cathode pole (1) and an anode pole (2); the air release valve (4) is arranged on the upper cover (3); the cathode inner bus bar (5) and the anode inner bus bar (6) are connected with the cathode pole (1) and the anode pole (2) respectively; and a sub-monomer (12) which is connected with the cathode inner bus bar (5) and the anode inner bus bar (6) is arranged inside the inner shell (20). The safe lithium ion battery has an extremely simple integral structure and low manufacturing cost; and the cathode inner bus bar and the anode inner bus bar are arranged in the battery, so that extremely uniform heat dissipation of a pole piece in a battery core can be ensured, and the battery can pass seven tests, namely a short-circuited test, an overdischarge test, an overcharge test, a falling test, a heating test, a needling test and an extrusion test.

Description

technical field [0001] The invention relates to a lithium ion battery, in particular to a safe lithium ion battery. Background technique [0002] Lithium-ion battery production technology has matured, and China has certain advantages in the direction of lithium-ion power battery technology. China is determined to become the world's leader in electric vehicles, and the number of pure electric vehicles will also rank first in the world in the future. Lithium-ion battery is especially suitable for mobile vehicle power supply, and is the preferred battery for vehicle power supply. [0003] However, due to the unreasonable structural design of lithium-ion batteries currently on the market, all existing lithium-ion batteries cannot pass through short circuit, over-discharge, over-charge, drop, heating, acupuncture and extrusion. This test has seriously hindered the development and progress of lithium-ion technology. Contents of the invention [0004] The purpose of the present...
