A green battery for Sub-Saharan Africa

EPFL startup hiLyte has developed an eco-friendly battery that will allow people in Sub-Saharan Africa to light their homes and charge their cell phones. The technology is currently being tested by families in Tanzania.

hiLyte, a startup founded by two graduates of EPFL’s School of Engineering (STI), has developed a clean, affordable battery using iron, water, coffee filters and carbon felt. With a single charge, the battery can power an LED bulb for five hours or charge a cell phone. Once used, the liquid inside can be safely released into the environment.
