|Batteries have been around for quite some time. New advancements in science have led to the development of many different types of batteries ranging in size and power. Unfortunately, current batteries contain hazardous materials that are environmentally unfriendly. A new and popular alternative to conventional batteries are fuel cells. Fuel cells eliminate the use of hazardous materials; however, they are rather large and may contain hydrogen, which is very explosive, making this alternative unsafe.
Researchers at Purdue University have developed an aqueous based battery that generates power using a regenerable electron source derived from biological sources. This battery is renewable and environmentally compatible. It is also safer and lighter than current alternatives such as the H2 fuel cell or lead/acid batteries. This technology has been designed for field use and has applications in areas where electronically powered sensors or devices implanted in the human body are used.
-Simplicity of design allows for economic development
-Safer and lighter than current portable energy sources
-Can be readily regenerated using biomolecules or living cells
