Abstract

The value of contact resistance between metallic current lead and electrode mass composite is one of the key parameters for determination of performance of energy storage devices, such as batteries, supercapacitors, etc. During discharge process of batteries the resistance of interface between electrode mass layer & the current collector influences on the battery voltage The surface of the aluminum foil, which used as a current collector for positive electrodes in lithium batteries is passivated by Al2O3 film that has a low electric conductivity. As result the energy and power battery are decreased. Our article is connected with technology for Li electrode production that insures the low interface resistance between electrode collector and electrode mass, the increasing the power of batteries, and stability the cycling. We have the strong opinion that the success of technology must be supported by nondestructive testing the initial materials, semi- and final product during batteries production.
