Promotion lecture by Anderson David Smith

Title of talk: Supercapacitors and their role in future technology and sustainability

Welcome to a public lecture by Anderson David Smith in connection with his promotion to the academic title Oavlönad docent. The lecture will be held online. 

Abstract of talk
With the threat of climate change and exponentially increasing energy consumption, humanity is compelled to move toward more sustainable energy solutions. In parallel, the number of electronic devices is increasing exponentially with the rise of Internet of Things (IoT). Not only are the number of electronic devices increasing, but they are requiring ever more functionality, and therefore power to operate. Currently, the overwhelming majority of these devices contain their own internal battery supply – which subsequently requires charging from the grid. These factors not only place increasing demands on energy grid, but also on battery performance - as consumers want to use their devices for longer times between charges and also use increasingly more power intensive applications. These pressures have led to a wide variety of innovative energy storage solutions – each with their own respective strengths and weaknesses.  For example, batteries can store relatively large amounts of energy at the cost of a relatively low power delivery and cycle life (the amount of times the device can be recharged before failure). In contrast, a device called a supercapacitor can store moderate amounts energy but deliver that energy at a far higher power and longer cycle life than batteries. This lecture will focus on developing supercapacitor technologies. Fabrication methods, materials and electrolyte combinations will be explored. Additionally, various trajectories for design improvements will be outlined. The lecture will further chart a course for beyond state of the art development, and explore potential applications which aim to meet increasing energy demands while offering the potential for greater sustainability.
