In many ways, we live in a battery-dependent society. But batteries are not just used in consumer goods.
The increasing global demand for batteries is largely due to the rapid increase in portable, power consuming, products such as lighting equipment, cellular phones, video cameras, toys, laptop computers, etc.
Each year consumers dispose of billions of batteries, all containing toxic or corrosive materials. Some batteries contain toxic metals such as cadmium, mercury, lead and lithium which become hazardous waste and therefore pose threats to health and the environment if improperly disposed.
When humans are stuck in an emergency situation, a natural disaster with a loss of power, batteries are still the most usable energy source for backup lighting systems worldwide.
However, batteries can seriously damage the environment and human health.
