BioSolar Claims Record with Low-Cost Energy Storage Supercapacitor

December 07, 2014 by Jeff Shepard

BioSolar, Inc. recently claimed record performance for its low cost energy storage supercapacitor. BioSuperCap, a next generation supercapacitor based on inexpensive conducting polymers designed to reduce the cost of storing the energy of the sun, has demonstrated stability for over 50,000 charge-discharge cycles, which is more than 10 times better than ever reported.

"We have shown that conducting polymers can be successfully employed for stable, high-performance supercapacitors," Dr. David Vonlanthen, a lead inventor of the technology and the company's scientific advisor said. "We fully demonstrated for the first time that the combination of polymers and redox-electrolytes yield supercapacitors that are inherently stable. The technology shows a stable performance over 50,000 charge-discharge cycles, which is more than 10 times better than ever reported for any previous polymer-hybrid supercapacitor designs. Conducting polymers are very promising materials for low-cost supercapacitors, as they are extremely cheap, easy to process, and highly conductive."

Dr. David Lee, the company's CEO commented, "Our eventual objective is to build a new generation of low cost polymer-based supercapacitors employing interpenetrating polymer-networks to give stable polymer-electrodes with very high charge-storage capacity."

Supercapacitors are high power and rapid charge-discharge energy storage devices. By integrating BioSuperCap as the front-end to battery banks, fewer batteries can be used, and daytime solar energy can be quickly and cost-effectively stored for nighttime use at a substantially lower cost. This potentially game-changing technology will allow users of solar energy systems to reduce their dependence or go completely off the electric utility power grid.
