The environmental impact of EV batteries has sparked many hot discussions. A report published by the trade-journal 'Environmental Science & Technology' and written by EMPA (Swiss Federal Laboratories for Materials Science and Technology) has revealed that the environmental impact of Li-Ion batteries is relatively small. Extracts: "The share of the total environmental impact of E-mobility caused by the battery (measured in Ecoindicator 99 points) is 15%." "The impact caused by the extraction of lithium for the components of the Li-ion battery is less than 2.3% (Ecoindicator 99 points)." "The major contributor to the environmental burden caused by the battery is the supply of copper and aluminum for the production of the anode and the cathode, plus the required cables or the battery management system." "The Li-ion battery plays a minor role in the assessment of the environmental burden of E-Mobility. Thus, a Li-ion battery in an BEV does not lead to an overcompensation of the potential benefits of the higher efficiency of BEV compared to an ICEV." Full report is attached. Twike 890
