Document Type and Number:

Japanese Patent JP2002542574

Kind Code:

A

Abstract:

A freestanding, microporous polymer sheet (52, 56) is composed of a polymer matrix binding an electrically conductive matrix. The polymer matrix preferably includes UHMWPE, and the electrically conductive matrix is preferably in powder form. The UHMWPE is of a molecular weight that provides sufficient molecular chain entanglement to form a sheet with freestanding characteristics. Multiple microporous sheets (30) can be wound or stacked in a package filled with an electrolyte to function as electrodes in an energy storage device (86), such as a battery. Metallic layers (81, 83) can be applied to the microporous sheets to function as current collectors in such devices.
