Development of Polymer Batteries
In the Nelson group (Department of Physics, Imperial College London, UK), I utilized organic semiconductors in energy storage devices. We fabricated polymer batteries that could be operated in aqueous electrolytes and studied their properties. The aim of the project was to explore sustainable materials for energy storage applications in safe electrolytes (aqueous electrolytes). See the pictures below for how we fabricate and operate devices, read more about our work in the open-access article (link 1)
Polymer batteries in action:
We developed devices that could power small devices. See for yourself how our developed devices can power a fan, check out the color changes during the charging/discharging of the polymer which we use to monitor the state of charge of the device. This device was used during the Science Festival at Imperial College to explain concepts for energy storage devices.
