Lithium-ion batteries power electric cars and produce notable CO2 emissions during their production. Each kWh requires about 73 kg of CO2 equivalents. For example, a 40 kWh battery, like in a Nissan Leaf, emits around 2,920 kg CO2. A 100 kWh battery, such as in a Tesla, emits about 7,300 kg CO2 during production.
The energy used during production also contributes to emissions. Factories consume electricity, often generated from fossil fuels. As a result, the carbon footprint of lithium-ion batteries is not solely derived from the batteries themselves but also from the entire supply chain. After their useful life, improper disposal can lead to chemical leaks, further harming the environment.
To minimize these emissions, manufacturers are exploring sustainable practices. Innovations such as recycling programs and more efficient production methods aim to reduce overall environmental impact. Understanding the carbon footprint of lithium-ion batteries is crucial for making informed choices about their use and for fostering cleaner technologies.
