Portable solar powered Electricity Supplies Using Recovered Batteries (PESURB)

Stage: Round 3

Approximately 600 million people globally lack home electricity but own mobile phones. Charging involves walking to charging stations, connecting phones to car battery chargers, incurring high charges. In parallel, millions of functional lithium-ion batteries are discarded annually. Recycling them for material recovery is expensive, with low reclaimed value. A more sustainable approach is to repurpose batteries with remaining functional lifetimes for new applications.

The project aims to repurpose end-of-life batteries into portable, low-cost, solar cell rechargeable power supply units for phone charging and low-energy lighting. Employing a circular economic approach, these units offer affordable energy for phone charging and low-energy lighting, employing circular economic approach to lithium-ion battery reuse.
