ENVIRONMENTAL IMPACT:
Li is extracted by hard rock mining which could cause a loss of biodiversity and destructive mining extraction could make the groundwater around the mine contaminated. The process of extraction of 1 ton of Li releases 15 tons of CO2 into the atmosphere which is a Greenhouse gas.
When extraction of Li has negative impacts on the environment then it’s a pointless argument to say that “EVs could replace petroleum engines which are not environmentally friendly”. On the other hand extraction of sodium has minimal impact on the environment.
AVAILABILITY:
Sodium is the 6th common element in the Earth’s crust, the higher percentage of Sodium is found in the form of Sodium Chloride which could be extracted on a large scale from the crystallization of seawater. Sodium is also 12,000 times more common compared to Li. So the high availability of Sodium over Lithium makes it a reliable battery technology.
