Abstract
The invention discloses a method for ultrasonically eliminating lithium ion battery lithium precipitation at variable temperature and pressure. A lithium ion battery obtained after lithium precipitation is placed in lithium ion battery variable temperature and pressure ultrasonic equipment, at set temperature and pressure, gas, liquid and particles inside the lithium ion battery are sampled through a battery external connection type preparation device and the microwave ultrasonic dispersion crushing technology, the gas, the liquid and the particles inside the battery are sucked away and cleaned away, reactants of metal lithium are input, after the precipitated metal lithium is completely eliminated, the reactants, impurities, water and the like are discharged, a solvent, lithium salt, additives, an electrolyte and the like are input, and the battery is charged and discharged. According to cathode and anode materials of the lithium ion battery and the sampling analysis result, a proper quantity of the electrolyte is added, or the solvent, the lithium salt, the additives and part of the electrolyte are supplemented, the lithium ion battery is repaired, and the lithium ion battery lithium precipitation problem is effectively solved.
Description
Technical Field
The invention relates to a method for eliminating lithium separation of a lithium ion battery, in particular to a method for eliminating lithium separation of the lithium ion battery by temperature-changing, pressure-changing and ultrasonic.
Background
The capacity of the lithium ion battery is necessarily reduced in the using process. Especially, when a plurality of lithium ion battery packs are combined into a high-voltage and large-capacity battery pack to be applied, for example, the battery pack is used as a mobile energy source to drive a new energy vehicle and is used as an energy storage power station to adjust the operation of a power grid, the lithium ion battery packs with large capacity, high power and long service life are essential conditions. During the use process of the lithium ion battery, the electrical property of the lithium ion battery is attenuated and the safety of the lithium ion battery is reduced due to various factors. For example: electrolyte is dried up, is converted into gas phase, and is subjected to short circuit, grain refinement of positive and negative active materials, asymmetric lattice change, less particle disorder, increased micro strain and the like caused by fragments, so that the pore structure in the original battery is changed, the migration path of lithium ions is changed, and lithium precipitation and lithium dendrite generation are caused. Lithium is separated out, dendrite is easily generated in the circulation process, and a diaphragm is pierced, so that safety accidents are caused.
Since metallic lithium, i.e., elemental lithium, is generated, it has a strong oxidizing property and is a highly dangerous product. After the lithium is separated from the battery, the safety of the battery is reduced, and particularly when the battery is extruded, impacted, vibrated and dropped by the outside, the battery is easy to explode and ignite, which means that a battery manufacturer often finds that the battery smokes or even explodes and ignites in the transportation process when the battery manufacturer does not drive out of a factory or transports the battery. The reason why the civil aviation bureau requires that the plane carrying lithium battery and the related portable electronic device are carried along and cannot be stored in luggage for consignment is that the space for storing the luggage in the warehouse is relatively narrow and is easy to collide or extrude, and the lithium ion battery is carried along as much as possible for ensuring the flight safety. The lithium is separated, so that the safety of the lithium ion battery is greatly reduced, the battery performance is greatly influenced, and the cycle, the capacity and the like are reduced.

For common consumer lithium batteries, a butt joint mode is adopted, and only the butt joint part meets the requirements of sealing, insulation and corrosion resistance; however, for the power lithium ion battery, it is necessary to adopt an insertion type, i.e. to select a thin non-metal tube with holes or a gas-permeable ceramic tube which is resistant to electrolyte corrosion, resistant to acid and alkali, not subject to chemical reaction or electrochemical reaction with the input gas, liquid and other substances, and insulated from the shell and positive and negative electrode plates of the lithium battery.
