Paper Based Biodegradable Batteries
Nowadays e-waste has been found to be a major concern owing to the increase in pollution level across the world. Conventional lithium-ion batteries used to juice up our electronics is a major component of e-waste. Not only it’s highly poisonous and lethal but also non-biodegradable.
Fortunately, Binghamton University researchers have found a solution to this problem. They have a created an eco-friendly, biodegradable battery made from paper and its claimed to be much more efficient than other proposed designs.
Seokheun “Sean” Choi, Associate Professor from the Electrical and Computer Engineering Department and Professor Omowunmi Sadik from the Chemistry Department have simultaneously worked on this project making sure the design is full-proof and the biobattery is self-sustainable. As per Choi their paper-based hybrid model of biobattery displayed a much higher power-to-cost ratio.
Mechanism of paper based Biobattery
A combination of paper and the engineered polymer has been used to design this biobattery. The key polymers used to maintain the biodegradable property of the battery were poly (amic) acid and poly (pyromellitic dianhydride-p-phenylenediamine). The battery is claimed to be highly cost-effective, lightweight and flexible.
Choi said that “Power enhancement can be potentially achieved by simply folding or stacking the hybrid, flexible paper-polymer devices” .
In the testing phase, the biodegradable factor of the battery was confirmed without the aid of any special factors, such as inducted artificial conditions or any microorganisms.
