Long-life lithium ion power battery for passenger tricycle

Abstract

The invention discloses a long-life lithium ion power battery for a passenger tricycle. The long-life lithium ion power battery comprises a lithium ion power battery, a multi-stage heat dissipation mechanism and a heat conduction mechanism, the multi-stage heat dissipation mechanism is arranged on the outer side of the lithium ion power battery, the multi-stage heat dissipation mechanism comprises a fixed shell, a heat dissipation finned tube is arranged in the fixed shell, the heat dissipation finned tube is wound on the outer side of the lithium ion power battery, and a liquid storage box is arranged on one side, far away from the heat dissipation finned tube, of the fixed shell. According to the invention, a corresponding cooling and heat dissipation mechanism is additionally arranged on the lithium ion power battery, so that the lithium ion power battery can be cooled and dissipated, the influence of temperature on the running performance of the lithium ion power battery is reduced, and the performance of the lithium ion power battery is remarkably improved; the battery polarization rate of the lithium-ion power battery is greatly reduced, the risk that internal components of the lithium-ion power battery are damaged due to the influence of the working environment temperature is reduced, and the service life of the lithium-ion power battery is prolonged.

Description

technical field [0001] The invention belongs to the technical field of lithium-ion power batteries, in particular to a long-life lithium-ion power battery for passenger tricycles. Background technique [0002] Lithium-ion power battery is a new type of high-energy battery. The negative electrode of lithium-ion power battery is made of graphite and other materials, and the positive electrode is made of lithium iron phosphate, lithium cobaltate, lithium titanate and other materials.
