>>PLASTIC BATTERY
>>Researchers at Brown University (Providence, RI) have constructed a
>>prototype battery that uses polymers to conduct electricity. Designers
>>took a thin strip of gold-coated plastic film and covered the tip with
>>polypyrrole and a substance that alters its conductive properties. The
>>process was then repeated with another strip of film, but with another
>>kind of conduction-altering chemical on the tip. The plastic strips
>>were then stuck together, separated by a membrane to prevent a short
>>circuit.
>>
>>The battery acts as a hybrid: it can store and deliver a charge (like a
>>battery), but can also be charged and discharged to deliver power (like
>>a capacitor). The design improved upon both concepts, delivering over
>>100 times the power of a standard alkaline battery and having twice the
>>storage capacity of an electric double-layer capacitor. It is as thin
>>as an overhead transparency, and about the size of an iPod Nano.
