The Recycling of Used Lithium Batteries The low molecular organic matter lithium hexafluorophosphate, heavy metals and plastics in lithium batteries can bring serious harm to the natural environment and human health. If the waste batteries can be recycled, not only can save a lot of natural mineral resources, but also eliminate the various hazards caused by waste batteries. Therefore, in recent years, the recycling of used lithium-ion batteries has become a key research area for various research institutes. The recycling of used lithium batteries is mainly to extract the relatively high value of non-ferrous heavy metals such as cobalt and lithium in lithium batteries. As the positive material in the lithium battery is complex, it may lead to the separation and extraction process of the metal material purity is not high. And lithium battery recycling processing equipment is good for sorting processing, which can improve the recovery rate of valuable metals. Used lithium batteries are physically recycled, the equipment is fast and efficient, and does not cause any environmental pollution. present disposal lithium batteries need lithium battery recycling processing equipment, ternary lithium battery recycling processing equipment, used lithium battery positive and negative electrodes processing equipment, lithium iron phosphate battery recycling processing equipment, lithium battery crushing and recycling equipment, these devices correspond to different lithium batteries for processing.

For cylindrical lithium ion batteries, the cathode electrode uses aluminum strips as the cathode battery tabs, because it needs to be welded on the cap by ultrasonic spot welder, therefore, it is necessary to have good welding strength. NO. Items Specifications 1 Appearance Uniform color, no oil, bright and smooth surface, no burr, no oxidation, etc. 2 Thickness（mm） 0.10±0.02 3 Width Refer to the specification of the specific model (tolerance ±0.05mm) 4 Length Refer to the specification of the specific model (tolerance ±0.05mm) 5 Flexibility 180° fold 6 times without breaking. 6 Welding performance When the surface of the battery tabs welding is covered with aluminum foil, it is qualified. For cylindrical lithium ion batteries, the anode electrode uses nickel strips as the anode battery tabs, because it needs to be welded on the bottom of the battery cans, therefore, it is also necessary to have good welding strength. NO. Items Specifications 1 Appearance Uniform color, no oil, bright and smooth surface, no burr, no oxidation, etc. 2 Thickness（µm） Refer to the specification of the specific model (tolerance ±0.02mm) 3 Width Refer to the specification of the specific model (tolerance ±0.05mm) 4 Length Refer to the specification of the specific model (tolerance ±0.05mm) 5 Flexibility 180° fold 4 times without breaking. 6 Welding performance More than 2/3 of the welded surface of the anode battery tabs is covered with copper foil, it is qualified. TOB New Energy provides customizable battery tabs, aluminum tab, nickel tab for lithium ion battery.
