A new approach to battery design could provide the key to low-cost, long-term energy storage, according to Imperial College London researchers.
The team of engineers and chemists have created a polysulfide-air redox flow battery (PSA RFB) with not one, but two membranes.
Our dual-membrane approach is very exciting as it opens up many new possibilities. Professor Nigel Brandon
The dual membrane design overcomes the main problems with this type of large-scale battery, opening up its potential to store excess energy from, for example, renewable sources such as wind and solar. The research is published in Nature Communications.
In redox flow batteries, energy is stored in liquid electrolytes which flow through the cells during charge and discharge, enabled through chemical reactions. The amount of…
