Polymer rechargeable battery

Scientists at the Central Electrochemical Research Institute, Karaikudi, have developed a re-chargeable conducting polymer-based dry cell battery. It is a cheap, safe and compact alternative to the conventional dry cells, highly useful for portable micro-electronic devices and household appliances like radio, transistors, tape-recorders etc. Already patented, the technology is poised for commercial exploitation.

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

These batteries give more energy density, and more charge-discharge cycles, with improved features such as longer shelf-life, weighing 25 per cent less than the conventional ones, environmental stability, and a high degree of processability. A unique separator makes it technologically superior.

The new technology is expected to result in the further development of other improved rechargeable polymer dry cell batteries. The new battery weighs 55 gm with a voltage of 1.34 V.
