Roland Piquepaille writes "Engineers at Brown University have built a prototype of a hybrid plastic battery that uses a conductive polymer. The system, which marries the power of a capacitor with the storage capacity of a battery, can store and deliver power efficiently. For example, during performance testing, 'it delivered more than 100 times the power of a standard alkaline battery.' Still, it's unlikely that such a device can appear on the market before several years."
