Thirty seconds of sunlight could boost the battery life of future smartwatches and other wearables by tens of minutes, thanks to a renewable and rechargeable battery prototype developed by the University of Surrey.
Surrey’s Advanced Technology Institute (ATI) has demonstrated how its new photo-rechargeable system, which merges zinc-ion batteries with perovskite solar cells, could allow wearables to spring back to life without the need to plug in.
Jinxin Bi, a PhD candidate at ATI and the first author of the paper, said: “This technology provides a promising strategy for efficient use of clean energy and enables wearable electronics to be operated continuously without plug-in charging. Our prototype could represent a step forward to how we interact with wearables and other internet-of-things devices, such as remote real-time health monitors.”
Surrey’s environmentally friendly, photo-rechargeable system is unique because of its elegant and well-matched structural design between the integrated battery and solar cell, allowing it to demonstrate high energy and volume density comparable to state-of-the-art micro-batteries and supercapacitors.
Dr Wei Zhang, project co-lead and expert in perovskite solar cells from the ATI, said: “This project is an example of how the University of Surrey is dedicated to producing research and innovation that equips humanity with the knowledge, tools and technologies to help us live better and more sustainable lives.”
Dr Yunlong Zhao, project co-lead and expert in batteries for wearables and implantables from the ATI, said: “The unique features in our ultrafast photo-rechargeable system could promote wide applications in self-powered wearable internet-of-things, autonomous power systems and emergency electronics. In addition, it will broaden the perception and insight of designing the next generation of miniaturised flexible photo-rechargeable systems.”

An affordable and sustainable alternative to lithium-ion batteries
Troy NY (SPX) Aug 03, 2022
Concerns regarding scarcity, high prices, and safety regarding the long-term use of lithium-ion batteries has prompted a team of researchers from Rensselaer Polytechnic Institute to propose a greener, more efficient, and less expensive energy storage alternative.
In research published recently in Proceedings of the National Academy of Science (PNAS), corresponding author Nikhil Koratkar, the John A. Clark and Edward T. Crossan Professor of Engineering at Rensselaer, and his team, assert that calci … read more
