Portable solar powered Electricity Supplies Using Recovered Batteries (PESURB)

点击翻译按钮获取中文摘要

Millions of functional rechargeable lithium ion batteries are disposed of each year. Some of these are recycledto recover the materials they are made of, but this is expensive and the recovered value is low. A better, andmore sustainable approach, is to identify those batteries that have remaining functional lifetimes and to usethem in new applications. This project is developing a process whereby these end of life batteries can berecovered, rapidly tested, and integrated into portable, low cost, lightweight, solar cell rechargeable powersupply units that can be used to charge mobile phones and to power low energy lighting. There are around 600million people globally with mobile phones that have no access to electricity at home. To charge them, theyoften have to walk for many hours to charging stations to connect their phones to car battery-based chargers; aprivilege for which there are high charges. The power supply units developed in this project will provide lowcost energy for phone charging and low energy lighting applications, using a circular economic approach to thereuse of lithium ion batteries.
