Polymer-Based (Polypyrrole) Battery

Brown Engineers Build a Better Battery – With Plastic. ‘It’s thin, light, flexible – and plastic. Brown University engineers Hyun-Kon Song and Tayhas Palmore have created a prototype polymer-based battery that packs more power than a standard alkaline battery and more storage capacity than a double-layered capacitor. Their work, published in Advanced Materials, will be of interest to the energy, defense and aerospace industries, which are looking at more efficient ways to deliver electricity.

Wikipedia – Polypyrrole. ‘A Polypyrrole (PPy) is a chemical compound formed from a number of connected pyrrole ring structures. For example a tetrapyrrole is a compound with four pyrrole rings connected. Polypyrroles are conducting polymers of the rigid-rod polymer host family, all basically derivatives of polyacetylene. Polypyrrole was the first of this key family of compounds to show high conductivity.’
