Scientists from Nanyang Technological University (NTU) have developed a battery.
And not just any old, regular battery, but an eco-friendly battery that’s as thin as a piece of paper, cheaper, and also biodegradable.
What is a printed paper battery?
NTU’s new version of December 14, 2021 described the printed paper battery, or the printed paper battery, as a sandwich.
Like what makes a good sandwich – ingredients plated between two slices of bread – the battery of printed paper includes cellulose paper that is sandwiched between the respective electrodes.
Just like a conventional battery, the printed paper battery also has an anode and a cathode, or a negative and a positive terminal, respectively, between which electrolytes flow.
These are the conditions required for the electrochemical reaction to produce electrical energy.
The anode or cathode are each printed on an opposite side of the cellulose paper, which has been reinforced with hydrogel to plug the spaces naturally present in the cellulose fibers.
The hydrogel also acts as a protective separator which prevents cathodes and anodes from mixing, and prevents short circuits.
According to the press release, the anode ink is mainly composed of zinc and electrically conductive carbon black, while the cathode ink on the other side can be made of manganese or any other metal.
Once the electrodes are printed, the battery is immersed in an electrolyte. A...
