摘要： The present invention relates to the field of battery cells, particularly to a pouch cell comprising a packaging seal, a heating element and a fault switch, wherein the fault switch will activate the heating element to generate heat to make the packaging seal delaminate when the inner space of the pouch cell reaches a predetermined pressure, such that the pouch cell vents. The mechanism and components of these venting concepts can be designed to be fully compatible with existing manufacturing methods and typical cell handling situations. The most favorable configuration has both vent device components outside the cell, with nothing passing through or even into the seal. Such a configuration has the advantage of having no impact on the seal integrity relative to a conventional pouch cell, is easy to manufacture, and has improved safety.

摘要： Herein is disclosed a process for recycling electrode material from lithium-ion batteries, comprising harvesting a mixture of anode and cathode electrode materials from waste lithium-ion batteries, and separating the anode electrode material from the cathode electrode material by means of dense liquid separation. The mixed anode and cathode material is suspended in a liquid that has a density between those of the anode material and cathode material, such that the anode material rises to the top of the dense liquid and the cathode material sinks to the bottom of the dense liquid. The thus separated materials can easily be collected and further purified and regenerated for reuse in new lithium-ion batteries, providing an efficient and low-cost method for recycling electrode active materials from waste lithium-ion batteries.
