Summary on Grant Application Form
Millions of functional rechargeable lithium ion batteries are disposed of each year. Some of these are recycled to recover

the materials they are made of, but this is expensive and the recovered value is low. A better, and more sustainable

approach, is to identify those batteries that have remaining functional lifetimes and to use them in new applications. This

project is developing a process whereby these end of life batteries can be recovered, rapidly tested, and integrated into

portable, low cost, lightweight, solar cell (or grid) rechargeable power supply units that can be used to charge mobile

phones and to power low energy lighting. There are around 600 million people globally with mobile phones that have no

access to electricity at home. To charge them, they often have to walk for many hours to charging stations to connect their

phones to car battery-based chargers; a privilege for which there are high charges. The power supply units developed in

this project will provide low cost energy for phone charging and low energy lighting applications, using a circular economic

approach to the reuse of lithium ion batteries.
