As the current collector for rechargeable lithium batteries, a paste is applied on top of the I2B to create the anode to the rechargeable battery.

This specialized Elecfoil’s shiny and matte side has similar and very low surface profile, and is used for the anode current collector in rechargeable lithium batteries for cellular phones, camcorders, and laptop computers.
I2B is available in a variety of thickness to meet product needs (6, 8, 10, and 20㎛) – less than 10㎛ for higher energy density or thicker to increase charge and discharge speed.
