If this technology is really better than the currently prevalent battery technology, then there is e.g. no need to prohibit internal combustion engines in Western countries!
We the people in Western countries do not need our elected busybody lifelong career politicians to dictate our future! Laissez fair, laissez passer!
So let's do more research and engineering! Given the enormous need and demand for better battery technology (e.g. for smartphones, portable computers) there is sufficient pressure on for scientists and businesses to develop it.
The element fluoride is much more abundant in the earth's crust than lithium.
If the price of electric vehicles becomes competitive (not by government mandate), then consumers and businesses will switch voluntarily since electric vehicles have advantages.
"Rechargeable batteries with higher energy densities are fundamental to meeting the ever-increasing requirements of consumer electronics, electric vehicles, and a burgeoning renewable energy economy. Fluoride ion batteries (FIBs) exhibit among the highest theoretical volumetric energy densities of any lithium or post-lithium ion technology under consideration. This potential capability arises from the coupling of highly dense anode (metal) and cathode (metal fluoride) materials through use of an anionic charge carrier (F-). However, at this incipient stage, the discharge/charge mechanism at both electrodes is still poorly understood; furthermore, the design of a liquid electrolyte system for long-term cycling stability has not been fully realized. ..."
