A full life cycle operation mode of injectable/pumpable lithium battery

Abstract

The present invention provides a full life cycle operation mode of the injectable / pumpable lithium battery, combined with the characteristics of the injectable / pumpable lithium battery, the battery isolation layer does not contain electrolyte when the battery leaves the factory, so that the battery can be transported to the user end or transfer station, no electrochemical reaction occurs inside the battery, and can be safely transported as non-dangerous goods; at the same time, when the battery life ends and needs to be scrapped, the electrolyte in the battery is pumped out through the pumping port and injected with a safener, so that the scrapped battery No electrochemical reaction occurs during transportation to the recycling station, and it can be safely transported as non-hazardous goods. In the present invention, the full life cycle operation mode of injectable / pumpable lithium battery includes a series of steps such as "battery delivery - safe transportation - battery activation - safe operation - maintenance regeneration / safe scrapping - safe transportation - recycling treatment - regenerative manufacturing" .

Description

technical field [0001] The invention relates to the field of lithium batteries, in particular to a full life cycle operation mode of an injectable / pumpable lithium battery. Background technique [0002] Lithium batteries have attracted more and more attention due to a series of advantages such as high specific energy, high voltage, small self-discharge, good cycle performance and long life. However, lithium batteries and lithium battery packs are classified as Class 9 dangerous goods. Generally, they are only qualified for the transportation of dangerous goods after they have been strictly reviewed by the relevant functional departments of the state and have corresponding facilities and equipment that can ensure the safe transportation of dangerous goods. During transportation, there are strict packaging requirements: 1) All lithium batteries (groups) must pass the UN38.3 test; 2) The outer packaging must be labeled with Class 9 dangerous goods and marked with the UN number;...

AI Technical Summary

Problems solved by technology

Affected by environmental temperature, air humidity, transportation vibration, shock and other factors during transportation, the battery is prone to problems such as liquid leakage, short circuit, forced discharge, electrical safety, etc., and may even cause the battery to catch fire and explode, affecting the safety of the lithium battery during transportation. Safety; at the same time, the falling off or loosening of electrode materials will also cause problems such as battery capacity decline and cycle life attenuation

[0004] At the same time, when the lithium battery life ends and needs to be scrapped, there are still electrolytes and active materials inside the battery. During transportation, the battery may leak electrolyte, and electrochemical reactions can still occur inside the battery. The battery is isolated due to internal isolation. Layer short circuit, or external electrode short circuit causes flatulence, combustion, explosion and other failures
