Year Awarded: 2018
Research Lab: Alberto Salleo
Alexander Giovannitti received a Diplom in Chemistry from Karlsruhe Institute of Technology (KIT) and an MRes and Ph.D. in Physics from Imperial College London. Alex is interested in the design of novel electrode materials which will pave the way for the development of safe and sustainable electrochemical energy storage. During his doctoral training, he developed and synthesized novel materials for the field of organic bioelectronics and particularly focused on the design of n-type polymers for accumulation mode Organic Electrochemical Transistors (OECTs). Additionally, as an EPSRC Doctoral Prize Fellow at Imperial College, he worked in the group of Prof. Jenny Nelson (Department of Physics) on the development of polymer batteries which can be operated in aqueous electrolytes.
Recyclable batteries – Towards sustainable and safe energy storage
The goal of Alexander Giovannitti’s research is to develop a recyclable battery based on solution-processable organic materials. To accomplish this, electrode materials will be designed to efficiently store electronic and ionic charges with safe electrolytes. Additionally, all materials used will be non-toxic and environmentally friendly. This will allow Alex to develop a recycling process for the battery and open up new pathways to explore sustainable electrochemical energy storage devices. The key to the development of scalable recyclable energy storage devices will be the ability to allow for processing electrode and electrolyte materials from solution. This will pave the way for the low-cost production of the battery (e.g. printing of batteries).
