Abstract:
A gradient interpenetrating polymer network electrolyte (56) for a rechargeable electrochemical cell, and a rechargeable electrochemical cell including said electrolyte (56). The interpenetrating polymer network electrolyte (56) consists of a first polymeric material (58) having a first set of electrochemical and morphological characteristics, and a second polymeric material (62) having a second set of electrochemical and morphological characteristics. A rechargeable electrochemical cell is made by disposing the interpenetrating polymer network electrolyte (56) between a positive electrode (54) and a negative electrode (52).
Abstract:
An electrochemical cell (10) includes first and second electrodes (12 and 14) with an electrolyte system (26) disposed therebetween. The electrolyte system includes at least a first and second layer (28 and 30), the second layer (30) being used to absorb an electrolyte active species and to adhere the adjacent layer of electrode material to the electrolyte (26). The electrolyte system further includes a process for packaging and curing the electrolyte after it has been incorporated into a discrete battery device.
