Full life cycle operation mode of injectable/extractable liquid lithium battery

Abstract

The invention provides a full life cycle operation mode of an injectable / extractable lithium battery. With combination of the characteristics of the injectable / extractable lithium battery, no electrolyte is contained in the battery isolation layer when the battery leaves the factory so that no electrochemical reaction occurs inside the battery when the battery is transported to a user end or a transfer station and the battery can be safely transported as a non-dangerous product; meanwhile, the electrolyte in the battery is extracted out through a liquid extraction port and the safety agent isinjected when the life of the battery is terminate and scrap treatment is required so that the scrap battery does not generate electrochemical reaction in the process of transportation to the recycling station and can be safely transported as the non-dangerous product. The full life cycle operation mode of the injectable / extractable liquid lithium battery comprises a series of steps such as "battery leaving the factory-safe transportation-battery activation-safe operation-maintenance regeneration / safe scrap-safe transportation-recovery treatment-regeneration manufacturing" and the like.

Description

technical field [0001] The invention relates to the field of lithium batteries, in particular to a full life cycle operation mode of a lithium battery that can be injected / pumped. Background technique [0002] Lithium batteries have attracted more and more attention because of their 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, only those who have passed the strict review of relevant national functional departments and have corresponding facilities and equipment that can ensure the safe transportation of dangerous goods can be qualified for dangerous goods transportation. In the process of 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 9 types of dangerous goods and marked with the UN numb...

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
