Membrane change batteries that store energy

The batteries and batteries we handle every day may have their days numbered. A team from the National Initiative for Nanoscience and Nanotechnology at the University of Singapore (NUSNNI) has developed a membrane capable of storing electrical energy . Unlike traditional batteries, which need electrolytes and complex structures, the new material consists of a simple membrane, very thin, which not only offers greater energy efficiency, but also more economical and environmentally friendly .

To manufacture The researchers used a polystyrene polymer that, when placed between two charged metal plates, is able to store a charge of 0.2 farads per square centimeter . This exceeds the standard capacitors, which have a storage limit of 1 microfarad per square centimeter. According to Xian Ning Xie stressed, author of the paper, the effectiveness of the new membrane lets you create simple devices and low manufacturing cost, with superior performance rechargeable batteries lithium ion, batteries lead-acid batteries and supercapacitors. The potential applications of these membranes are hybrid vehicles from solar panels and wind turbines , tla and as they say its creators in the journal Energy & Environmental Science .
