Thank you for elaborating. Do you happen to know how much more efficient a vehicle with half a tank of gas vs. a full tank of gas is? It is a negligible amount.

Lithium can be recycled. Coal gets used up. Both have negative impact on the environment. Only one of them can sustain long term energy needs. The focus will eventually turn to large-scale recycling of lithium batteries instead of mining.

Electric vehicle batteries will become safer over time with advancements such as solid-state cells that will be making their way in to electric vehicles within the next 5-10 years.
