Foam-like, Shock-free Batteries Made From Plants
A team of researchers from KTH Royal Institute of Technology in Sweden and Stanford University in US has invented elastic, foam-like batteries made from wood pulp. These innovative batteries are so powerful that they can withstand heavy shock and stress. According to Max Handi, a researcher at KTH and Harvard University, a lot of such useful materials can be manufactured from the pulp obtained from trees. In the process of preparation of these batteries, the raw products such as tree fibres and cellulose are used to produce a new kind of material, aerogel. The researchers believe that the new wood-based aerogel material can be utilised for making three-dimensional structures that can store more power and require less space for storage as compared to conventional batteries that were quite large, stored less amount of power and were discharged easily.
For making this material, nanocellulose was broken down from trees and was made roughly one million times thinner. These thin layers of nanocellulose are first dissolved, then frozen and then freeze-dried to evaporate moisture from the obtained product, without passing it through the liquid state. After this, to keep the product away from collapsing, the molecules of the resultant material are stabilised. The resultant product is soft, light and strong and has a structure that resembles foam contained in a mattress, but a little more hard and porous.
The aerogel material, which has a surface as that of human lungs, was coated throughout the surface within the aerogel with a kind of ink that conducts electricity. Thus the batteries prepared, are shock free, foam-like and stretchable. According to the manufacturers, the batteries can be deployed in electric car bodies and in garments that have linings.
