New Delhi, Oct 21: Indian scientists have developed a re-chargeable conducting polymer-based dry cell battery which is a cheap, safe and compact alternative to the conventional dry cells. The technology, developed by scientists at the Central Electrochemical Research Institute, Karaikudi, has been patented, an official release said today.

The dry cells are highly useful for portable micro-electronic devices and household appliances like radio, transistors, tape recorders and the like.

Currently conducting polymer dry cell batteries are not available in the consumer market, the release said.

Conducting polymers are new materials whose properties can be designed to meet the need of the applications and tailored from insulating to semi-conducting and metallic.
These materials called synthetic metals are slowly replacing many metals and inorganic semiconductors in a big way in many devices like energy sources, display devices, control of electromagnetic radiations, sensors and the like.
