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.
Inside a battery, there is a component that is thinner than a human hair, but plays an important role of prompting electrical reactions during charging and discharging the battery. What would that be? It is the current collector. Today, we’ll delve into the current collector. What is current collector?
The current collector, a thin layer of about 10μm, induces electrochemical reactions during charging and discharging by delivering electrons from external circuits to active materials or vice versa. Ingredients of current collectors Ingredients used for current collectors for lithium-ion batteries differ by electrode.
Ingredients of current collectors Ingredients used for current collectors for lithium-ion batteries differ by electrode. The most commonly used material for the anode current collector is copper foil, since it offers high electrical conductivity and good stability against electrochemical reactions within the operating range of the carbon electrode.
58 current collectors, as shown in Fig. 1a. Commonly used cathodes include LiCoO2, 61 such as SiOx to improve the capacity . During discharging, Li-ions stored at the 62 anode move to the cathode, generating electrons and forming current flow. The 63 process is reversed when the battery is being charged. Electrolytes consist of lithium
Main requirements for current collectors in lithium-ion batteries 119 a) Electrochemical stability. Current collectors must be electrochemically stable 120 against oxidation and reduction environments during battery charging and 121 discharging.
By enabling Li-ion diffusion through the current collector, the authors show notable advances in high-rate charging using state-of-the-art Li-ion battery materials.
