Carbon based Cathode materials for Aluminum-ion battery

Despite all the advantages, aluminum-ion batteries (AIB) are still facing a number of challenges that hinder the development of AIBs including the lack of proper cathode materials, low working voltage, insufficient specific capacity and poor cycling stability. Recently an advanced new AIB system with break-throughs in both conceptual cell design and electrochemical performance has been reported. The new AIB system is composed of an Al foil anode, a graphite cathode and an ionic liquid electrolyte. In a typical test, the AIB cell delivered a specific capacity of about 70 mAh/g with a well-defined discharge plateau of about 2 V. More surprisingly, it cycled 7500 times at a super high current density of about 4000 mA/g without capacity decay. Graphitic carbon-based cathode materials show very promising electrochemical performance. However, similar to Si electrodes in lithium-ion batteries, carbon materials also experience a dramatic volume change over repeated charge/discharge, leading to instability and safety issues. This project will explore different carbon based materials, that might enhance capacity and limit volume expansion, as possible cathode materials for AIBs.

Shaikat Debnath is a PhD student at Australian Institute for Bioengineering and Nanotechnology, while he has obtained the UQ-Research training Scholarship to support his research. His research area is carbon based cathode material for aluminium-ion batteries. Before that he did his Master of Engineering Science from University of Malaya, Malaysia in 2015 and Bachelor in Electrical and Electronic Engineering from Chittagong University of Engineering and Technology, Bangladesh in 2009. Apart from it, he holds his position as Executive Engineer of Bangladesh Power Development Board, Government of the People's Republic of Bangladesh, where he had been working since 2010 and is on 'study leave' at the moment. He is a member of Institute of Engineers, Bangladesh.
