Even while electric vehicles are considered green options (as opposed to petroleum-based vehicles), there has been some valid concern about the nature of the batteries used in EVs. The most popular, the Li-ion battery – let’s face it – is not the most eco-friendly.

The clean energy brigade is, however, working on new battery technologies that would be less harmful to the environment. The sodium ion battery has emerged as the most popular as it is less expensive and greener in its quintessence.
