RECHARGEABLE ELECTROCHEMICAL CELL Russian patent published in 2005 - IPC

FIELD: flexible design of rechargeable electrochemical cells using superlight and superstrong conducting and insulating materials.

SUBSTANCE: proposed electrochemical cell has one or more pairs of electrodes. First electrode has flexible shell made of ion-conducting insulating material and flexible conducting substrate disposed inside shell. Flexible conductor can be made of conducting material in the form of fabric or gauze introduced in active material in the form of powder granules. Second electrode is also made in the form of flexible shell made of ion-conducting insulating material that accommodates conductor inserted in electrically complementary active material layer. Proposed cell also has means for applying pressure to electrode assembly, membrane separator, and counter-electrodes for maintaining permanent contact under pressure between each separate particle of electrode active materials, separator, and conductor (substrate). One or both electrodes can be made as sintered, molded, glued, or suspension-like structures.

EFFECT: reduced mass and enhanced strength of electrochemical cell electrodes.
