Aluminum foil usage for lithium iron phosphate batteries

Can aluminium foil be used as a cathode for lithium iron phosphate composite?

In this paper, aluminium foil with a tunnel structure was used as a cathode to prepare a lithium iron phosphate composite by electrochemical deposition using propylene carbonate as the electrolyte solvent, and lithium nitrate, ferric nitrate and phosphoric acid as raw materials.

Why is aluminum foil used in lithium ion batteries?

High surface area, good electrical conductivity, and low weight. Aluminum foil is used as a cathode current collector for Lithium-ion batteries. It is a critical component in the construction of the battery, as it helps to conduct electricity and acts as a barrier to prevent the electrolyte from leaking.

Can aluminium foil be used as a battery collector?

The aluminium foil can be directly used as a positive current collector, with a lithium sheet as the negative electrode. After mounting into a battery, an electrochemical performance test is performed. The battery test results show an initial discharge capacity of 95 mAh/g, 79 mAh/g and 59 mAh/g at 0.1 C, 0.2 C and 0.5 C, respectively.

Can aluminum foil and cathode materials be separated from lithium-ion batteries?

Efficient separation of aluminum foil and cathode materials from spent lithium-ion batteries was achieved using a low-temperature molten salt, presenting the advantages of low cost and sustainable use.

What is aluminium foil used for?

The composite material is closely combined with the aluminium foil. The aluminium foil can be directly used as a positive current collector, with a lithium sheet as the negative electrode. After mounting into a battery, an electrochemical performance test is performed.

Can lithium iron phosphate batteries be recycled?

In this concept paper, various methods for the recycling of lithium iron phosphate batteries were presented, with a major focus given to hydrometallurgical processes due to the significant advantages over pyrometallurgical routes.
