Researchers develop battery of biodegradable printed paper


Batteries take up a lot of space and are generally difficult to dispose of. Precisely in this regard, the researchers want to adopt a new approach: they have an ultra-flat approach. Energy storage which can be printed and biodegradable.

A very interesting approach to new types of electricity storage

This is interesting basic research currently being compiled by scientists at Nanyang Technological University (NTU) in Singapore. contribution And at the beginning
Study in advanced sciences Row: She has developed biodegradable thin sheet zinc batteries. Intended field of application: In flexible and portable electronic systems, one could “one day” offer a space-saving and significantly more environmentally friendly option.

The basis of the new battery is “Hydrogel Reinforced Cellulose Paper”. The electrodes are then printed on both sides using the traditional screen printing process. For “anode ink”, scientists want to find a good combination with zinc and carbon, for cathode ink, we are currently trying to use manganese and nickel. According to the researchers, the use of other metals can also be considered here.
New battery design and structure

When the printing process is complete, the paper battery is submerged in an electrolyte. In the last step, a thin layer of gold is applied to the electrodes to increase the conductivity. The current “proof of concept” finished product is 0.4mm thick.

strong and durable

Even at this early stage of the trial, the energy storage system can provide very promising results. As explained by the NTU team, a 4cm x 4cm square can run a small electric fan for at least 45 minutes. In another experiment, more practical features were demonstrated: the power to the LED was not cut even by cutting parts of the battery.

Lee Seok Woo, Associate Professor of NTU and co-author of the study: “We believe that the paper battery that we have developed can solve the problem of electronic waste, because our printed paper battery is not toxic and does not no aluminum or plastic casing required to encapsulate the battery components. This approach is certainly exciting, and now the technology has to prove itself.
