Paper batteries paper batteries, as the name suggests, a thin paper - like battery can be as arbitrary as ordinary paper. Bending is safer and more convenient than liquid combustion battery, and the cost is also very low. So this novel battery technology is becoming more and more popular in scientific research laboratories around the world, but it is not a new thing to develop paper batteries, and surprisingly, it can also be recharged by water.
the Portuguese CENIMAT laboratory, which recently studied the battery project, said they developed a new technology that could be used to recharge paper batteries by water. Elvira Fortunato, a research member, said that the paper batteries using this new technology can absorb electricity from the water vapor, that is, when the air humidity in the indoor environment reaches 40%, the paper battery can automatically charge it for itself, very miraculous. The principle researchers did not tell, but I believe that if we master this technology, we will be able to use batteries in more special fields.
