Embodiment Construction

[0030] A method for recycling power batteries for new energy vehicles, comprising the following steps:

[0031] (1) Discharge: Perform discharge operation; according to the power supply interface, voltage, battery capacity and other parameters of the power battery, use the corresponding battery discharge instrument to discharge the failed power battery to remove the remaining power of the power battery, so as to ensure that the subsequent processes can Do it safely. The discharge method adopts one or a combination of constant current discharge, constant resistance discharge and constant power discharge.

[0032] (2) Preliminary disassembly: disassemble the components of the power battery to obtain metal parts, non-metal parts, wires, circuit boards and battery cells; when the power battery is composed of several battery packs, continue to disassemble the battery pack shell and connecting parts, take out the battery cell.

[0033](3) Detection and classification of battery ce...

Abstract

The invention discloses a method for recovering power cells for new energy vehicles. The method comprises the following steps of: (1) discharging the expired power cells for removing the remaining energy of the power cells to ensure that the subsequent processes can be performed safely; (2) initially partitioning; (3) detecting and classifying the performance parameters of single batteries; (4) disassembling the useless single batteries to take out the positive and negative pole pieces thereof; (5) performing elemental analysis on the obtained positive and negative pole pieces, based on the result of elemental analysis, determining the mixing amount of different batches of raw materials according to the contents of the elements and the proportion of each major element of a target product, and extracting the metal elements by hydrometallurgy to prepare the target product; and (6) sorting the employable single batteries by a battery sorter according to the residual capacitance of the single batteries, grading and classifying based on the capacitance, and then applying to products according to actual requirements.

Description

technical field [0001] The invention relates to a method for recycling power batteries used in new energy vehicles. Background technique [0002] In order to get rid of the dependence on the increasingly depleted oil resources and reduce the serious pollution of the environment caused by traditional vehicle exhaust emissions, electric vehicles have attracted more and more attention from all over the world. The "National "Twelfth Five-Year" Science and Technology Development Plan" clearly states that during the "Twelfth Five-Year Plan" period, the development of the new energy electric vehicle industry will be vigorously promoted. By 2015, the number of electric vehicles will reach 1 million, and the output value is expected to exceed 100 billion yuan. [0003] All or part of the energy of electric vehicles comes from power batteries, and the life of power batteries is generally only one to three years. Compared with automobiles or electric vehicles, power batteries need to ...
