Switzerland has developed a paper battery that can be activated with water

Switzerland has developed a paper battery that can be actuated with water 

Developers from Switzerland have created a battery that can be considered environmentally friendly and completely biodegradable, because it's made of paper carpeted with table swab. 

 Graphite patches are deposited on one side of the paper strip to form the cathode. On the other side is zinc, which allows you to produce an anode. In both cases, a special makeup is used. To start the battery, you just need to drop a many drops of water on the paper, after which the swab will dissolve and the redox response will begin due to ionic conductivity. 


The zinc will oxidize, which will releaseelectrons.However, also the inflow of electrons will go to the cathode, where a reduction response will take place using oxygen, If you connect a cargo to the connections. That is, in fact, it'll be an ordinary battery. As noted, the process will continue until the water dries up or until the end of the zinc force. 

Regarding the power of such a battery, during the first wetting, the voltage without cargo will be1.2 V, with the alternate – about0.5 V. In both cases, the battery worked for an hour. It's also noted that the battery was suitable to power the electronic alarm timepiece for about an hour. 


So far, the result has problems. For illustration, you still need to find a way for the battery not to dry out ahead of time, but this is formerly a purely engineering task. The marketable launch of the product of similar batteries has not yet been blazoned, but scientists believe that they will find operation as provisory power sources.
