A freestanding, microporous polymer sheet (52, 56) is composed of a polymer matrix binding and electrically conductive matrix. The polymer matrix preferably includes UHMWPE, and the electrically conductive matrix preferably is 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.

L'invention concerne une feuille polymère microporeuse rigide (52, 56), constituée d'une matrice polymère liant une matrice électro-conductrice. La matrice polymère comprend de préférence du polyéthylène de masse moléculaire très élevée (UHMWPE), et la matrice électro-conductrice se présente de préférence sous forme de poudre. Le UHMWPE possède une masse moléculaire assurant un enchevêtrement des chaînes moléculaires suffisant à former une feuille présentant une certaine rigidité. Plusieurs feuilles microporeuses (30) peuvent être enroulées ou empilées dans un emballage rempli avec un électrolyte, en vue de servir d'électrodes dans un dispositif de stockage d'énergie (86), tel qu'une batterie. On peut appliquer aux feuilles microporeuses des couches métalliques (81, 83) afin qu'elles servent de collecteurs de courant dans de tels dispositifs.
