Zinc is the fourth-most used metal worldwide, behind iron, aluminum, and copper.  Further, the world is naturally abundant in zinc, and resources are available to meet future demand for many generations.  By contrast, lithium batteries depend on raw materials that are too scarce to enable the widespread and rapid transition that the realities of global warming demand.

At the end of its useful life, zinc recovered from batteries can be recycled through well established channels and, unlike lithium, reused in new batteries.  In addition to being sustainable during use, zinc also has recycling advantages over lithium during the end-of-life phase by reducing energy use, lowering emissions and minimizing waste disposal.
