Environmental Problems Lithium Batteries Cause
Lithium batteries are now widely used as part of everyday life. You can find them in mobile phones, digital cameras, watches, pacemakers, hearing aids and as portable battery banks. Each year consumers use billions of batteries, all containing toxic or corrosive materials. Some batteries contain toxic metals such as cadmium and mercury, lead and lithium, which become hazardous waste and pose threats to health and the environment if improperly disposed
Consumption Of Natural Resources
Production, transportation and distribution of batteries consumes natural resources, thereby contributing to an accelerating depletion of natural resources. Rechargeable batteries consume less nonrenewable natural resources than disposable batteries because fewer rechargeable batteries are needed to provide the same amount of energy.
Climate Change And Global Warming
The increase in the average temperature of the Earth’s surface is caused by an increasing greenhouse gas effect. The manufacture and transportation of batteries emits exhaust and other pollutants into the atmosphere, thereby contributing to the greenhouse effect. Per unit of energy delivered, rechargeable batteries contribute less to global warming than disposable batteries. This is because less greenhouse gas emissions are associated with the manufacture and transportation of rechargeable batteries.
Photochemical Smog Pollution And Air Acidification
Exhaust pollutants undergo photochemical reactions which produce toxic chemicals including ozone, other harmful gases and particulate substances. The thermal inversions associated with large cities can lead to a dangerous buildup of photochemical smog, which is known to cause human deaths. Air acidification is the accumulation of acidic substances in atmospheric particles. These particles, deposited by rain, have an impact on soil and ecosystems. Rechargeable batteries contribute less to these atmospheric effects than disposable batteries because they contribute less to air pollution.
Ecotoxicity And Water Pollution
Potential toxic risks are associated with emission of battery chemicals into aquatic ecosystems. Improper or careless handling of waste batteries can result in release of corrosive liquids and dissolved metals that are toxic to plants and animals. Improper disposal of batteries in landfill sites can result in the release of toxic substances into groundwater and the environment.
