Which current collector is best for a lithium ion battery?

Conventional current collectors, Al and Cu foils have been used since the first commercial lithium-ion battery, and over the past two decades, the thickness of these current collectors has decreased in order to increase the energy density.

What is a lithium ion battery?

Lithium-ion batteries are the state-of-the-art power source for most consumer electronic devices. Current collectors are indispensable components bridging lithium-ion batteries and external circuits, greatly influencing the capacity, rate capability and long-term stability of lithium-ion batteries.

What are the different types of current collector materials for batteries?

Six different types of current collector materials for batteries are reviewed. The performance, stability, cost and sustainability are compared. 2D and 3D structures of foil, mesh and foam are introduced. Future direction and opportunities for 2D and 3D current collectors are provided.

Who makes Lib batteries?

In 1998, Johnson and White systematically characterised some commercial LIBs produced by five dominant manufacturers , including Sony, Moli Energy, A & T Battery, Sanyo Electric and Matsushita Electric Industrial.

How much does a carbonaceous current collector cost?

Last but not least, carbonaceous current collectors are cheaper than metal current collectors. According to the online quotation from Goodfellow, carbon fabric with a thickness of 0.15 mm costs $ 440/m 2, which is equivalent for $ 60/m 2 for carbon fabric with a thickness of 20 μm.

What is a commercial current collector?

Commercial current collectors are Al and Cu foils for cathodes and anodes, respectively . Fig. 1. a) Schematic diagram of a typical Li-ion battery, b) the weight percentage of main components in LIBs , c) historical timeline of the development of current collectors for LIBs in both industry (yellow) and academia (red) [13, 16, 19, 20].
